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. Here are a few we love:
-
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.
- FileSalvage (OS X, $80):
File Salvage for Mac will set you back some serious coin, but it's one
of the best tools to pull data off of a connected hard drive in OS X. It
can recover virtually any type of file on multiple partition types, and
prides itself on its ability to recover from damaged drives and corrupt
media. If you want an alternative, try Data Rescue for Mac ($100).
- TestDisk (Win/OS X/Linux, Free):
If you're not afraid of the command line, TestDisk is an open source
utility that can run against almost any platform or partition type. It
does a great job of recovering data quickly, and won't do unnecessary
writes against the drive you're trying to recover from.
-
Bootable Linux distros for drive recovery: If you're not interested in messing around with apps (or paying for them), consider burning a bootable CD or USB key with BackTrack, Bart PE, or SpinRite
on it, so you can boot to an OS that's not your primary drive, avoid
writing or touching the drive you want to recover from, and run a host
of recovery and forensics tools against that drive that are highly
effective and completely free. Photo by Roman Soto.
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.
Step Three: 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 lotfor 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. I've had good experiences with
OnTrack. DriveSavers is well known and loved, both because they
came to the rescue with free drive recovery services after September 11, 2001 and more recently helping
Wired's Mat Honan recover from his epic hacking.
Both companies do a superb job at pulling data even off of drives that
have been formatted, overwritten, or even severely physically damaged.
Keep in mind though that these services generally run in the tens of
thousands of dollars and higher.
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!
