200 ways to revive a hard drive
This is a situation that every tech support person has faced or will face at least once: a failed
hard drive .
In this particular case, a user was getting errors like "disk 0 error" and "invalid drive specification."
Here were the other facts in the case:
• The data wasn't backed up.
• The problem came out of nowhere.
• The user had accessed Setup and tried to manually enter the settings for the drive type when
"Auto" didn't work.
• There was no startup disk made by this machine.
Reviving a drive like that one—even if only long enough to copy its data before you throw the
drive in the garbage—is a tough challenge.
When this document was first compiled back in 2001 data recovery was (and still is
for many) a very expensive option.
While the Freeze it, Hit it, and Drop it options are still experimented with by some, the current
size and sensitivity of the newer larger hard drives makes these options extremely risky
and definitely NOT recommended for hard drives with a capacity that’s greater than 1
gig. And even then some of the operation suggested here should be approached with caution.
Getting it wrong by trying to save some money will only end up costing you more if you then
decide to pass on your hard drive to a data recovery company...
If your hard drive does work and you are attempting to recover a FAT or NTFS file
system, then this FREE step by step guide could help you get back your lost files.

These tools or tips will work. But we thought you'd enjoy reading what your fellow IT Professionals
use and had to say on this subject. Enjoy!

When this document was first produced back in 2001 data recovery was (and still is for many)
a very expensive option. While the Freeze it, Hit it, and Drop it options are still employed by
some, the current size and sensitivity of the newer larger hard drives makes these options
extremely risky and definitely NOT recommended for hard drives with a capacity that’s greater
than 1 gig. And even then some of the operation suggested here should be approached with
caution. Getting it wrong by trying to save some money will only end up costing you more if
you then decide to pass on your hard drive to a data recovery company...
There are, broadly speaking three classes of data recovery, Logical, Electronic, and Physical.
Logical
Where the FAT, NTFS or other file structure has been corrupted either by accident
or on purpose or individual filed or folders have gone missing. The hard drive has
not suffered damage to the components of the hard drive itself.
Electronic
Component failure on the PCB (the circuit board on the bottom of the hard drive)
in the motor or internally.
Physical
Internal damage to the hard drive, damaged platters, head crashes, damage to
the motor, or head rack signal amplifier. You need a clean room and plenty of
experience to have any chance of a successful outcome here.
Logical recoveries are becoming an affordable option for those people who are familiar with the
risks involved with data recovery. Software tools that are now available for this task vary
greatly in their capability, complexity and cost.
Careful research should be done before any work is done on the damaged hard drive. If you
are able, get another hard drive and experiment. Format it, Fdisk it, delete files and partitions
and learn how the data recovery software operates under these various conditions.
Before to start work on your own or your clients hard drive back it up, the backup mantra is
one that you all should be familiar with by now! There are tools available to backup (or image)
a hard drive that has been fdisked!! Use them. Ghost software is not suitable for this task,
then perform your recovery attempts on the image not the original.

Some electronic data recoveries are also within the capability of many technically minded
people who spend much of their time working around computers. Remember your static strap
when removing PCB boards.
A repair of this nature can be as simple as swapping the PCB board. With a board from a
matching working hard drive. Data recovery companies keep an inventory of many 1000’s of
hard drives for events such as this.
If a PCB swap does not work then the most common problem is that the match was not close
enough. In any production run of a particular model of hard drive there could be as many as
several dozen changes in firmware upgrades, components on the board, etc.
To have the best possible chance all of the code numbers and letters on the top plate of your
drive and its parts donor should be the same. If you have no success then find a reliable data
recovery firm near you as you has done as much as you can.

Freeze it
From: Travis Standen
One trick I have learned as a technician, when the problem is data-read errors off the platters
themselves, is to freeze the hard drive overnight. It makes the data more 'readable,' but for a
one-shot deal. If this data is critical, and you have a replacement hard drive (which, if it's a
drive failure, you probably do), then you can hook up your frozen hard drive and immediately
fetch the data off before it warms up.
From: Thedeedj
If the problem is heat related, I put the drive in the freezer for about 15 minutes to cool it
down... sometimes this gets the drive up long enough to copy any critical files...
From: Itguy1
Put the drive in a waterproof sealed bag, put it in the fridge for an hour or so, then have
another go.
From: Kelly Reid
Well, I won't start playing with your specific situation, too many steps or possible solutions
where everything starts "If that last thing didn't work try..."
But I'll give you one for free that was a nice hero moment for me. Had a drive where it
sounded like the drive motor was engaging but not getting anywhere, so we stuck it in the
office freezer for an hour! I'll be darned if it didn't work. The drive was up long enough to get
the data ghosted to another drive and we turfed it, even though it sounded fine at that point. I
can't really take credit for it though—I had heard it in some geek bull session but I thought it
was some jedi-geek urban myth. Goes to show you that you know you're really screwed when
you say something to the effect of "Okay, hold on tight, I'm gonna try something I saw in a
cartoon once but I'm pretty sure I can do it"

If this drive isn't spinning up, putting it in the freezer for about an hour will usually get the
drive spinning again so you can copy needed files before the drive warms up again. The first
thing you want to do is run a disk utility like Norton disk doctor or wddiag (if it's a western
digital drive) to verify whether the drive is working mechanically or not. If it is a master boot
record problem, sometimes running Fdisk/mbr will correct the problem. It could also be a
virus, and a program like F-prot will look at the drive as a physical unit. As an A+ PC
technician I have seen this problem many times. Usually if the drive is not making a clicking
sound I am successful in recovering the data.
From: Scott Greving
I've run into this scenario numerous times. One time it involved the main Novell SYS volume
on our HP File Server. I was really sweating as the server would not boot. I took the drive out
and put it in a freezer for 30 minutes. I then reinstalled it into the file server and Presto! I was
up and running. Needless to say I quickly mirrored the drive onto another and got rid of the
bad drive. In stand alone client systems, the method I've had the most luck with reviving
drives from death has been removing the drive, firmly tapping the top of its case several
times, and then re-installing it making sure all cables are secure. I've had a better than 60
percent success rate with this method.
From: jphillips
If the drive is spinning and you are experiencing these kinds of errors, my experience has been
that you are out of luck.
If the drive is not spinning, I have been able to remove it from the computer and 'spin' the
drive on a flat smooth surface (much like spin the bottle). This will usually free the drive and
when placed back in the machine, it will boot. You should immediately back up you data after a
successful boot, because the problem will return. The next 'fix' was actually given to me by a
Compaq technician several years ago. I had a drive that would not spin and he told me to put
the drive in a plastic bag in the freezer overnight and then install back in the computer. Believe
it or not, the drive booted. I have only tried this the one time.
From: John Turcotte
In the past, when a drive has failed after it has been running for a short period, I have
removed it from the machine and placed it in a freezer for a couple of hours, then hooked it up
again. It sometimes will run long enough to remove the data to another safe storage medium.
From: David Furlow
One of the methods I have used before (sometimes even successfully) is to actually remove
the drive from the PC, place it in the freezer for a day, then quickly put it back in the machine
and try to access it. Why does this work? Who knows, but I heard about this tactic years ago,
and it has saved my behind on a couple of occasions. (Of course, if it comes back up, back up
the data immediately.... Guess that should go without saying.)

Hard drive revival:
A technique I have learned is if you bring the temperature of the hard drive down to the
freezing point by putting it in a freezer first and then taking it back out, somehow the
condensation from bringing it back to room temperature helps revive it for about 20 minutes.
It can be repeated about 5-6 times tops. Long enough to get out any important files that need
to be backed up. It has been proven to work a number of times.
From: Christopher Post
How do you bring a hard drive back to life?
My situation:
Half of a volume set goes south on a WinNT server, no good backup and an angry boss
screaming about the data being mission critical.
My solution:
** A bit unorthodox but, it has saved my butt! **
• Turn off the server.
• Take out the failing hard drive and wrap a static bag around it.
• Throw it in the freezer conveniently located in the break room.
• Pray for 1 1/2 to 2 hours.
• Leaving the hard drive in the bag, quickly plug the drive back into the server. (Just plug the
in cables and go.)
• Cross fingers, turn it on, and move all data off the drive as fast as you can! Then add a tape
drive and start backing the dumb thing up!
My so-called logic:
Metal contracts when it is cold.... so the platters shrink and increase the clearance for the
read/write heads.
From: Chris Poole
Put the drive in the freezer for about a week and then you can usually get one last read off the
drive.
From: Cheyenne Robert Alspach
Here are some drive recovery tricks that have worked for me, in the order that I do them. Try
booting the drive and copying the data off after every step.
1. Hold the drive upside down, making gravity change the head geometry ever so slightly.
Vertical is also another option.
2. Slightly rap the drive with your knuckle, (but nowhere near hard enough to damage the
drive).
3. Try the drive in another machine, (slight drive voltage change assumed to be the miracle
worker here).
4. Rap the drive just SLIGHTLY harder than you did above in 2.
5. Freeze the hard drive in the freezer for two hours, and place in a plastic zip lock bag to
prevent condensation from forming on the drive when you plug it back into the system, (head
