How to Recover Data From a USB Hard Drive

With the amount of media that people like to carry around with them these days, a USB hard disk has become a nearly essential piece of equipment for computer users. However, because these kinds of disks are carried around so much and subjected to so much use, they are vulnerable to breakdown, which can lead to an irretrievable loss of mountains of data. But with the proper techniques, it is possible to retrieve precious data from a broken USB hard drive provided It is still being detected by your computer.

First Thing First: Determine the Cause

Hard Disk External

If you suddenly find your hard drive malfunctioning, it may be for reasons that will fall under two categories: mechanical or logical disk failure. Mechanical failure is happens because of wear and tear that can be brought about by any number of things. When trying to figure out the cause of your hard drive's failure, try to remember whether you have recently dropped, hit, shaken, wet or heated (overused, left in a car on a hot day, etc.) it. If you have, then the problem is probably mechanical. If not, then it's possible that you're looking at a logical disk failure. You'll know this is the case if your computer recognizes the hard drive but simply cannot read the files. You should be relieved because recovering your data will be much easier than if your drive had failed mechanically.

How to Recover Data From a USB Hard Drive

What to Do in Case of Mechanical Failure

If you plug your hard drive into your computer through the USB port and your computer doesn't read it, don't panic just yet! Stay calm, and try attaching your drive internally, like a regular hard drive. If the computer is then able to read the drive, then your data should be intact. All you need to do, then, is transfer your files to a backup and then have your hardware repaired.

But if your computer can't read the drive even when it is internally connected, then you should turn to professional data recovery services (unless you happen to be experienced in this kind of thing, in which case you wouldn't be reading this article).

What to Do in Case of Logical Failure

An example of logical disk failure is when the Master File Table or MFT in Windows has been corrupted. In this case, your disk still retains your data, but is unable to properly access it. If this is the case, then follow these steps to recover your files:

Don't load any more data. This may seem obvious, but is nevertheless important to say. You might be tempted to just accept the "loss" of the files and start using your hard drive again without fixing it, but this will only lead to more problems for you. Prepare another hard drive. You will use this to store your recovered files. Purchase or download for free any reliable data recovery software. Normally, this will get the job done. All you need to do is, scan your USB hard drive for deleted files and the software will show you a lit of files you've deleted before. You just need to select those files and start the recovery process.

If you've done all this, and are still unable to recover your files satisfactorily, then you should think about availing of professional services.

Definition of a Hard Drive

The computer hard drive, which is simply a component within your system, stores your data for you permanently. When you want to locate a document or look at your pictures, your computer operating system locates them on your hard drive and then displays them on your monitor. A simple definition of a hard drive is a sealed device which has the ability to store digital data on self contained magnetic disks, called platters, which are written to and read by a special head at the end of an arm which operates very similar to a household record player. If you picture in your mind a record player, also called a turn table, it has a needle at the end of an arm that plays the music as the record spins. The part in your fixed disk which reads the data is positioned extremely close to the spinning platter and moves very quickly to different areas of the platter where the data needed at that moment in time is stored.

When you are using a laptop or desktop computer, and you double click on a folder you want to open, the operating system, such as Microsoft Windows XP or Vista, actually tells the fixed disk that it would like to see the contents of the particular folder which you double clicked on. The platter within your system must spin around to where the head is able to retrieve the data which is magnetically stored on the hard drive and then send it to the operating system so that Windows can display the contents of the folder on your computer monitor. Now, this is a very basic definition of a hard drive in action because in reality there are many components involved in this process such as the CPU (Central Processing Unit), RAM (Random Access Memory), the motherboard, etc.

Hard Disk External

Basically the hard drive stores all of the computers information such as documents, pictures, and movies for example. When the computer itself is powered off, and eventually powered on again, the data on the hard drive remains intact exactly as should be expected. This is called permanent storage. The data will remain intact on the hard drive until the computer user deletes the permanently stored data. Without this important system component there would be no way for us to permanently store large amounts of data.

Definition of a Hard Drive

The hard drive is also often referred to as a fixed disk because once it is mounted inside of a desktop, external enclosure, or a laptop computer, there is no need to remove it. If you think about a CD (Compact Disc) or a DVD (Digital Video Disc), they are each capable of storing digital data but they are obviously not fixed in any fashion. Also, they are dependent on an optical drive in order to have their data be read by a computer. In the case of a laptop computer or an external enclosure, the hard drive is certainly portable, but the disk itself stays securely fixed in the laptop or the enclosure.

Secure Hard Disk Delete

Secure Hard Disk Delete is important for all. Some of us consider sending back the disk back to manufacturer for removing the data the most secured way. But it is not. There have been instances reported where data of some one's get transferred on your disk and vice- versa. To avoid being in such a situation people thought it is wiser to buy a new disk and totally destroy the existing disk. Okay it would be wiser but when there is already so much e waste, then you think it's a wiser option. No would be the answer but then what are the other ways for securely deleting hard disk. Well you can either try for a disk degauss.

For degaussing the disk there are special machines that help in creating the magnetic fields that help in deleting the data completely. If you don't have the machine, then take the help of a data deletion company.

Hard Disk External

Another inexpensive method for hard disk erasure is to buy a safe data deletion software program available online. These programs are available at economical prices online. The step by step easy to understand procedure helps you to delete the data permanently without any problem. For PCs this is something good & as a safe option as well.

Secure Hard Disk Delete

Many small and big business houses badly require hard disk delete program to protect the interest of the customers, and employee. For them it is recommended to use the help of professional. This will highly eliminate the chances of data leaving any imprint on the disk and ultimately help in secure hard disk deletion.

A Quick History Of The Floppy Disk

Even though there is a lot to be said about floppy drives, these forms of data storage are mostly mentioned in a historical capacity. While you can do a data backup to a floppy disk (assuming your computer even has a floppy drive) it is definitely not recommended. There are many other methods of backing up your information that are far more reliable and offer far higher capacities.

The floppy disk was the first truly portable form of information storage for computers. Sure, you could move tape drives around at risk of severely damaging the tape, and you could move punch cards from computer to computer, but both of these storage options were unwieldy. When they were invented, floppy disks could store up to 1.44MB of data.

Hard Disk External

As you can probably tell already, 1.44MB of storage space is nothing in the world of today where most of the files you will be saving are several or even several hundred megabytes in size.

A Quick History Of The Floppy Disk

The floppy disk was invented by Dr. Nakamats, who apparently did most of his thinking at the bottom of his swimming pool. The floppy disk drive was just one of the many things that he invented while sitting on the bottom of his pool. Almost as soon as it was invented, the floppy disk made punch cards obsolete - they were just so portable, reliable, and easy to use.

The first floppy disks were invented in the 1960's by IBM. The disks were 8" across and were used during the 1970's on the computers of that time. However, it was the smaller floppy disk drives that were commonly used in people's homes.

There were two sizes of these commonly used floppy disks, the 5.25" and the 3.5" floppy. If you did not have a computer during the early 1990's or 1980's, then you probably only know of the 3.5" floppy. These typically came in sizes between 720KB and 2.8 MB - though the 1.44MB floppy disk was by far the most common size.

The 5.25" floppy was the older version and was a bit floppier than the 3.5" version. These could only hold between 100KB and 1.2MB of data.

Most computers do not come with floppy disk drives anymore. The reason for this is that they are no longer in wide use, and most of the important information that was on computers that only had floppy disks for data storage has since been moved onto newer computers or storage media.

You may still need floppy disks if you need to communicate with older technology. Some lab computers at certain schools are so old that they need floppy disks to retrieve data from and store data to.

If you need a disk drive and do not already have one on your computer, you can purchase an external drive at most computer stores. Hurry, though! This type of data storage is so out of date that it is likely that these external drives will not be available for much longer. These drives can be connected to your computer through USB or alternatively with a parallel port.

Unless the computer that you are using is too old to have USB connections, you should not be using a floppy disk to bring information to and from school or work anyway. Instead, you can just use a USB flash memory drive, which is much smaller and harder to damage.

Do not try to back up your computer on floppy disks! The number of disks that you will need will quickly make this into a time consuming and expensive task!

The Maintenance of HP Hard Drive

The workhouse of the computer is the hard disk. Therefore, it is important to know the functions and working of the hard disk. The files that we save are magnetically recorded onto the platter. The platter is placed inside the hard disk. The platters in most of the hard drives are usually mounted on a spindle. With the help of this spindle, the platter is able to spin faster and the speed can reach up to 15,000 times/ minute. The platter is two sided, and is mounted on a single arm which has a slider.

The head can move across the surface with the help of the platter is two sided. In this way the head can read and access the data. The unit of data held by the platter is tracks/inch. The track is equal to 1 concentric ring around the disk. The track is further divided into sectors, and the sector is equal to approx. 512 bytes. The saved data on the disk is referred accordingly to its sector and track.

Hard Disk External

The process of data collection can be made faster by de-fragmenting the hard disk periodically. The de-fragmenting can be done with the help of Windows Disk Defragmenter, which reorganizes the scattered data on the hard drive. Once, the de-fragmentation is done, the files on the hard disk run faster and more efficiently. The de-fragmentation process shifts the files to the beginnings that are used most often. This shifting of files is done so that the hard disk can load these files immediately when they are accessed.

The Maintenance of HP Hard Drive

The SATA (Serial ATA) hard drives are the next generation of ATA (Advanced Technology Attachment) hard drives. The HP SATA hard drives have been developed and designed to offer its users the best and optimum prices for the entry level servers. The HP SATA hard drive also offers its customers the affordable solutions for external storage deployments in the environments with low workload.

The hard disk Cleanup

The Windows Disk Cleanup application sorts through the disk and deletes unused and temporary files. In this way space can be made available on the disk which speeds up the operations.

The ScanDisk utility

The files in normal daily routine are regularly read from and written to the disk, often in small chunks. The ScanDisk utility runs when the computer had to restart after a crash or is turned off without properly shutting down the system.

The ScanDisk scans the disk to detect if there are any errors on the hard drive. If it finds any errors on the hard disk, the ScanDisk marks the cluster of sectors containing the error as unusable. In this way no data can be written to or read from that portion of the disk.

ScanDisk should probably be done after every two or three month's time. The ScanDisk can also automatically repair some of the detected errors. If the errors are more severe, then these errors can be repaired by reformatting the drive. The bumps or scratches are known as the hard errors, which are the physical damages to the disk. These hard errors cannot be repaired. If the number of hard error increases, then the hard drive needs to be replaced. The hard drive can run smoothly well past the time it has become obsolete with the help of simple maintenance.

5 Tips For Buying An External Hard Drive

So you've finally decided to buy an external hard drive as a backup option for your computer. This is a great choice for you because you're making backing up your data faster and easier than you could ever have imagined. You're also making your data far more portable in larger quantities than before.

You'll no longer be limited to storing a few hundred megabytes or even several gigabytes. Nope. Now you can look forward to portable and reliable storage capacities ranging into terabytes. That frustrating desktop computer or network file server backup job just got a whole lot easier.

Hard Disk External

If you've never bought an external hard disk before then there's a few pointers here that may help to have on your shopping list before you go and make that final purchase.

5 Tips For Buying An External Hard Drive

1. Buy A Brand

Do yourself a huge favor and buy a brand name that you easily recognize. Sure these may cost a little more than brand x but with computer accessories like this you really do get what you pay for. If a Western Digital 100GB external drive costs 0 and another brand x 100GB drive costs why do you think that is? Because the company likes you? Because they like making smaller profits? No it's because it's a cheaper drive made with inferior parts that's going to break a lot sooner than you might expect.

The other aspect of sticking with a brand is your warranty. For example Maxtor, Western Digital and Iomega are all reliable companies and well known for their external hard disks. If something goes wrong with your drive you can have it fixed. With brand x you'll probably not even be able to find an email address that you can contact the parent company on. Is saving a few dollars worth that risk?

2. Google It

Whatever brand or model you decide on make sure you do some research before purchasing. Always, always Google the exact brand and model of the drive you're considering buying. Look for reviews and especially any feedback on how reliable a drive is. You'll be very surprised to find that some companies have particularly bad reputations in terms of equipment reliability and what's known as the "click of death" in the external hard drive industry.

Spend time in Google checking out your prospective purchase. You'll be glad that you did.

3. Connectivity

When it comes to external hard drives you'll need to choose carefully when selecting your connection types. Your external hard drive will support either USB or Firewire. Firewire is the fastest option available at the moment but your computer may not support this. The vast majority of modern computers will, however, feature a USB port.

The next question now is what type of USB port do you have - USB 1.0 or 2.0? If your computer only has a USB 1.0 port then your external hard drive is going to transfer data VERY slowly. USB 2.0 is the minimum you should consider as connection options for both your computer and your external hard drive. If you don't have a USB 2.0 port (also called HiSpeed USB) on your computer you may need to get a USB 2.0 card fitted.

4. Speed

Now of course we need to talk about speed. The faster your hard drive operates the faster data will get transferred to your computer and vice versa. Without boggling you with comptuer jargon there's a couple of technical things you need to include on your shopping list.

Seek time - this needs to be 10ms (milliseconds) or less

Buffer size - more is better. Get a drive with at least a 4MB buffer.

RPM - higher is better. 5400rpm as a minimum. 7200rpm being preferred.

Stick to the above basic pointers and you'll do just fine.

5. Size

This is the simple part of the whole "buying an external hard drive" equation. Buy as much as you can afford. If you can afford 100GB then get it. However if you can afford 200GB then get it. Then again if you scraped together a few dollars more you could afford 300GB then do it.

This isn't a sales pitch. Far from it. There is simply no such thing as having too much data storage space. The 160GB drive that I have here was filled up in a little under a month. Currently a terabye option sounds good for my future needs.

Always add 50% to your data storage requirements. Honestly. You'll thanks yourself within the first 90 days of buying your external drive.

Hopefully now you'll be better prepared for purchasing your new external hard drive. It's one of the best purchases you'll ever make.

Primary Master Hard Disk Failure IDE Hard Disk Error and Recovery

IDE (Integrated Drive Electronics) is a commonly used hard drive interface. Motherboards are generally provided with two IDE connectors, IDE0 (Primary IDE) and IDE1 (Secondary IDE). To each of the IDE connector, we can attach two devices at the maximum, where one is given the highest priority and referred as Master Drive while the second one is given low priority and is referred as Slave drive. But sometimes, system prompts that it can't recognize the IDE hard drive as it has failed. These are the cases when Hard Disk Recovery becomes necessary to retrieve lost data.

One of the symptoms that it shows, while hard disk failure is the occurrence of error messages as:
"Primary Master Hard Disk Failure"

Hard Disk External

As the error message suggests, system is referring to failure of primary master hard drive. It is also sometimes denoted as drive 0, which is entirely dependent upon number of drives installed and BIOS type.

Primary Master Hard Disk Failure IDE Hard Disk Error and Recovery

Cause of Error Message:

Hard disk has failed to correctly communicate with the system, most likely due to physical failure. The corresponding causes could be: read/write head crash, actuator arm failure, spindle motor crash, disk controller problems, firmware corruption or electronic issues. In few cases, bad cabling could also be a root cause for this error message. These cables may turn faulty due to issues like heat, wear and tear etc.

Solution

Users are required to consider following solutions:
o If hard disk has gone physically bad, system user should immediately turn it off. The hard drive should be replaced with a new one and data can be restored from a recent backup on the new drive. If backup is unavailable or faulty, Data Recovery service can serve the purpose of optimum recovery.

o If bad cabling is the issue, user can replace the faulty cables with new ones.

About Data Recovery Service

½ Terabyte Notebook PC Drive

Seagate's 2.5-inch half-terabyte 5400 and 7200 rpm drives - Momentus® 5400.6 and Momentus 7200.4 - deliver the best combination of capacity, mobility and durability for mainstream and high-performance notebook computers, external storage solutions, PCs and industrial applications requiring small form factor.

Technical Details

Momentus 5400.6 and Momentus 7200.4 hard drives are the fourth generation of Seagate's laptop family to use PMR. The Momentus 5400.6, a 5400 rpm drive, combines a powerful Serial ATA 3Gb/second interface and capacities ranging from 120GB to 500GB with an 8MB cache. The Momentus 7200.4 hard drive, with its 7200 rpm spin speed and a Serial ATA 3GB/second interface, delivers true desktop performance.

Shock Resistance

Both Momentus drives are built tough enough to resist up to 1,000 Gs of non-operating shock and 350 Gs of operating shock to protect drive data, making the drives ideal for systems that are subject to rough handling or high levels of vibration. For added robustness in mobile environments, the Momentus 5400.6 and 7200.4 are offered with G-Force Protection, a free-fall sensor technology that helps prevent drive damage and data loss upon impact if a laptop PC is dropped. The sensor works by detecting any changes in acceleration equal to the force of gravity and parks the heads off the disc to prevent contact with the platter in a free fall of as little as 8 inches and within 3/10ths of a second.

Power Efficient

Seagate's new Momentus drives are low on power consumption, allowing notebook users to work longer between battery charges, and are virtually inaudible thanks to Seagate's innovative SoftSonic(TM) fluid-dynamic bearing motors and QuietStep(TM) ramp load technology.

Warranty

All Momentus and Barracuda drives are backed by Seagate's leading five-year warranty.

Data Recovery: Hard Drive Failure

La prima cosa da fare è determinare se un problema meccanico o logica. Problemi logici sono quando il file system è danneggiato e il computer non riesce a leggere il disco. Il costo del recupero dei dati non può essere troppo alto per la logica fallimento che spesso è possibile utilizzare il software per eseguire la scansione del disco per vedere se è possibile trovare i file. In questa situazione, il disco rigido è simile ad una cartella di lavoro di grandi dimensioni che conteneva tutti si strapazzate e il computer non è possibile aprirlo. Voidon't need a data recovery expert at this point, but just some software to reorganize that filing cabinet and get your data out.

If it's an external hard drive that needs data recovery, the process is the same - download some data recovery software and test to see if the data can be recovered. Mechanical problems are of a different sort altogether. These are usually accompanied by obvious evidence of clicking or other strange sounds. The procedure involved here is to power down your computer, remove the drive and plug it into another computer, usually using a USB cable adaptor.

Again, you'll use data recovery software to see if the contents of the drive can be read. If you're lucky you'll be able to transfer all of the content to another drive. If you're not, it's time to find a hard drive data recovery expert. At this stage data recovery prices can vary wildly, so picking an expert should be based on how valuable the content is to you. If the drive was in a work computer you should calculate the cost of lost productivity -- how much time, resources and energy will be spent trying to re-do work, gather information lost on the bad drive, etc.

Data Recovery: Hard Drive Failure

Personally, in 15 years of full time computer work I've seen about three or four hard drives go bad. The first one I lost was tragic. The later occurrences didn't bother me so much because I had by this time (fueled by the first bitter experience) learned to have more than one back up drive! These days I now use three different backup drives (in addition to my main computer drive) to save work files, music, photos, emails and other important files. The great news is that hard drives are cheaper than ever so it's easy to spend a little money in the short term, for some assurance in the long term that your data is safe.

Best Laptops for Personal Use

Laptops are great for on the go work and play. They come in a variety of sizes with features that can accommodate different tastes and styles. When purchasing a laptop it is good to know exactly what you will be using it for. This means you need to decide if you want a laptop that can write and record DVDs or one with a lot of internal space or a killer speed for watching and downloading movies or playing games.

Size matters in the laptop world. Some say the bigger the better while others want smaller screens so that their laptop is even more portable. Smaller laptops are known as netbooks and are just as good as their larger competitors. We will start with a small sized screen, which is one Toshiba. Its screen measures 11.6 inches and it comes pre installed with Windows 7 Home Premium. This laptop also features a 2GB CPU and a 250 hard drive, which is adequate space for your internet and computer needs. This netbook is great for on the go use.

For a larger screen, but not too big you can always pick up a Toshiba Tecra that features more than style and space. This laptop has a 15.6-inch screen with a 3GB CPU and 320GB of hard drive space. What sets this one apart from others is that it offers DVD+/-RW, which means that you can actually burn movies from it, and add them to your home collection. It is like your own personal entertainment machine.

Picking out the perfect laptop or netbook can be a daunting task. There is research to be done and numerous choices that do not end once you have chosen the perfect screen size. Be sure to know what you want and don't settle for less. Computers can do a lot these days. You just have to know exactly what you are looking for to get the one that matches your wants and needs.
