Dear IT Solutions Support Team, I have a hard drive with valuable information on it, but I can\’t seem to access it—the drive is either damaged or erased. Is there any way I can see what\’s on the drive and get it off? By the ways, I living in locally – Warrington, please help. Sincerely, Manish Kiran
Dear Manish Kiran,
Don’t worry, we’re not going to ask where you got the drive, but there are plenty of ways to examine it and see if any of the data is recoverable. With a little time, the right tools, and some care, you may be able to get some data off of that drive.
Step One: Assemble Your Tools and Examine The Drive’s Condition
The first thing to do is make sure you have the tools required to connect this drive to another computer safely. Ideally, you’ll have some kind of SATA/IDE to USB cable or USB drive enclosure or sled that you can mount the drive into and connect it to your computer easily. Sure, if you have a desktop and like getting your hands dirty you can try to install the drive as an internal one, but an external connection is faster and easier.
Next, take a look at the drive itself. Is it damaged in any way? Are the pins bent or broken? Make sure that the drive is in good enough condition to actually use before you try anything in the first place that may damage it even further. If the drive is too physically damaged to attempt recovery, you may need more drastic measures that we’ll get to later. If everything looks good and you have the equipment required to connect the drive to your system, we can proceed.
Step Two: Grab Some Data Recovery Software and Connect the Drive
Before you do much else, make sure your antivirus and antimalware tools are up to date. You don’t know what you’ll find on this drive, and you don’t want it to start misbehaving once the drive is connected to an active system. Once you’ve done that, it’s time to download and install some data recovery tools.
Recuva (Windows, Free): Personally, Recuva has been indispensible. Made by the same folks behind CCleaner, Recuva makes data recovery simple and easy. if you’re only interested in browsing and restoring selected files off of the drive, Recuva is a great option. Alternatively, check out Undelete Plus for Windows.
A number of these tools can recover from formatted drives, especially if the data hasn’t been overwritten. We’ve tackled this topic before, and used Knoppix as our bootable linux distro, but the steps apply to the ones we’ve mentioned as well. For more reading, check out this old but still largely accurate guide at Linux.com to recovering from formatted drives.
Remember, the less you work with the drive you want to recover data from, the better. As you read from the drive, you run the risk of exacerbating any damage it may have. The more you write to the drive, the more likely you are to overwrite something you want to recover. Bootable linux distros—many of which have tools like TestDisk pre-installed (among other, more advanced tools)—are the best way to go if you’re familiar with the method and if you’re interested in recovering entire partitions, or making a non-bootable drive bootable again. If you’re just looking for files and you know the drive was in a Windows system or a Mac, a stand-alone app is an easier way to go.
You can try the freezer method – If the drive won’t spin, put it in a plastic sandwich bag, seal it up and leave it in the freezer overnight, this will cause the metal platter to hopefully shrink just a tiny bit (I didn’t believe it until I tried it, but it works!). Remove from the freezer the next day (at least 24 hours later) and give it one or two hard taps on the side (the thinner, longer side) against a table or counter top, then plug in and give it a try right away, if you wait too long the platter will get back to room temp and may re-expand so you have to be quick when you do it. Also everyone asks me wont tapping a HD on a counter damage it? Well if its already dead you cant make it any more dead so it either works or it doesn’t!
Finally, Get Out the Big Guns (and Your Wallet)
Okay, so the drive is physically damaged, has been wiped and overwritten, or nothing else you try works and you really, really need the data off of it. You’re even willing to pay a lot for it. We’re not going to ask why, but at this point it’s time to call in the professionals.
Pick up the phone and call the folks at DriveSavers and OnTrack to see what they can do for you.
If the drive is yours, or the data you get from the drive is valuable, we’d strongly suggest you make sure your data is backed up, both locally and online. After all, it’s better to be able to get the data back quickly than have to jump through these hoops every time a drive fails. Remember, every hard drive will fail eventually, it’s just a matter of time. Now go forth, use this knowledge for good, and recover!
