with. The second set is important. Sometimes the BIOS doesn't auto correctly. Listen to the

HD. If it powers up normally by sound (no strong thumping sound) and the platters seem to

spin up, you still have a chance. If the drive spins up and then down or if it emits a strong

thumping sound, the hard drive is toast and only a professional recovery company with a clean

room can help. If the HD doesn't spin up at all, occasionally you can gently slam it down to get

stuck platters unstuck and it will spin up long enough to back up your data. The HD is toast

physically at this point, and it needs to be replaced before trying the slam technique. There

were also a few older HDs that had the flywheel exposed, and you could nudge it slightly and

they would spin up long enough to back up the data. Again these are last resort techniques

and you ARE planning on replacing the HD anyway. From here, one of several software

products are available to assist you as long as the drive spins up physically to assist the

technician. Most of these products can read drives with damaged FAT tables or missing sectors.

And it could be just a simple matter of losing the Active attribute for the partition! Also, viruses

can cause this by blasting the partition table, and some of the professional revival products can

assist from here.

Good luck!

• If the drive is not spinning up on power-on, I'll lightly rap on the side of the drive enclosure

with the handle of a screwdriver while listening for the platters to begin to spool-up.

• If it doesn’t spin up, I'll increase the pressure of each rap until it does start spinning. I've

gone to the extreme of picking up an externally mounted full height 5.25" disk drive and

slamming it continuously on the desk while it was starting up.

• I did this for over six months until the drive finally died completely, but I did extend its life

and it never had corrupt data on it. Of course, it was all backed up. If the drive won't spin,

then you aren't going to recover the data.

• You can you a third-party utility like RESCUE that reads the drive directly using its own

operating system and saving individual files and directories to another drive. I've recovered

entire drives this way it is time consuming but it works. When all else fails, send it to the

professionals.

Before you do the following, make sure that the controller is not the problem or a cable on

backwards, etc., by taking the drive out of the computer and putting into another one to see if

it’s the computer causing the problem. If the other items have been checked, then do (what

we call) the slam test.

If the drive is dead the only thing you can really do is:

1. Find out if the person needs any important info that you might be able to get off of

computer.

1a. If person has data they cannot live without and the drive is not running, take the drive out

of the computer and slam it down to the desktop to get the motor running. Nine out of 10

times, this will get the motor running long enough to get data. If needed you can also send the

drive into a White Room to have them get the info.

Actually, the solution Isn't mine. We had several Dell PCs and the C drive went out on one

(with no current backup, of course). The Dell tech came out with a new drive but the warranty

didn't include data recovery for which they wanted a $5,000 deposit and offered no

guarantees. I asked the tech if there was anything we could do on our own to get the drive to

spin up so we could get a backup. "Well", he replied, "there is one thing I've done that

sometimes unsticks the drive." He then took the drive out and slammed it flat down on the

desk as hard as he could. After putting it back in the drive, it spun up. I was advised to back

up the data before shutting down the system as "the slam" doesn't always work and seldom

works a second time. Fortunately, once was enough in this case. The data was backed up to a

portable tape drive and the C drive was replaced and restored.

I have used several ways to solve the same issue. The reason is the fact that a hard drive is a

hard drive is a hard drive, or is it? The answer is NO. If a hard drive is failing it’s usually

because it is legacy equipment that often doesn't even support LBA mode. But, sometimes it

isn't even the hard drive that’s causing the problem. Say what? That's right. By in large, I first

approach this situation by asking the user how much hard drive space he/she used to have.

Usually the answer is over 512 megabytes. But, again, you'll be surprised. Secondly, I ask the

user if this is the first time this situation has occurred and whether or not he/she knows if we

are dealing with a new or old computer. Armed with the above answers. I usually solve this

problem by performing a combination of the tasks described below.

1) Test the motherboard BIOS/CMOS battery. Often, the hard drive is just fine. But, the

internal battery is dead. Some computers like a few Packard Bells I have dealt with have LBA

and 32-bit mode turned off by default. Those settings may have been enabled during

assembly, but now that the battery is dead they are set back to factory settings (when the

user turns his/her computer off) rendering the hard drive inaccessible. Solution: Change the

internal battery and enable CMOS LBA/32-bit mode.

2) Ask if the computer has been moved recently. Often, when computers are moved, data

cables are detached from hard drives and/or motherboards. Obviously, without a data or power

cable, a hard drive will never work. Solution: Reattach cables and be prepare to actually

replace them.

3) Worst case scenario. It is the hard drive that does not seem to respond. Then, replace the

hard drive with a new Master drive and install the faulty drive as a Slave drive. Make sure you

install the same Operating System used by the Slave on the Master. Then, proceed to probe

the Slave drive. Ideally, at this point you should use diagnostics tools such as Micro-Scope

from Micro2000. If you have experience, you should not close the computer box making sure

that the Slave drive is within reach. Twice, I have been able to restart a hard drive after

gently banging on it (once as Slave and once as a Master.) Don't miss the boat. Even if you

happen to restart the faulty Slave drive, you must copy your info to the Master so that you are

not placed in the same situation again because the next time you may not be as lucky. The

above procedure works whether the drive is an IDE or SCSI drive. However, when using SCSI

hard drive, you may have to test the SCSI card as well. I am leaving now to fix a drive that

belongs to a RAID

When a drive is really gone—cannot be read at all—due to a physical failure, I employ a trick

that has yet to fail me.

1. Install the replacement as an additional drive.

2. Remove the bad drive and smite it firmly on both edges (bang it on something solid)!

3. Reinstall it, reboot, and it will work long enough to get the data copied to the replacement

drive.

4. I haven't had the opportunity to check this step yet but I think it should work. If it's the

boot drive that's bad, mirror the boot partition to the replacement drive, then break the mirror,

remove the bad drive rejumper, and boot to the new one.

The rest of the solutions

From: Scott Wittell, MCP A+

I had to laugh when I saw this easy fix, and it does work. We were able to bring back a failed

drive in an older HP server running NetWare 4.11. First step is to remove the drive from the

machine. Second, hold the drive flat in your palms. Third, shake the drive a few times in an

up-and-down motion, like you're trying to hammer a nail. Don't let the drive hit the floor

though. I've used this technique on numerous occasions, works every time.

The Hair Dryer Method

For the last resort (when the drive really did die, it-is-not -even-spinning type crashes), there

is a possible solution that comes from the early days of hard drives. Back then you were not

supposed to turn them off—I don't know why but IBM said never turn them off unless you are

standing there. One of our main computers was housed in a closet where I could not hear it

well and had a power supply failure that apparently took days to complete. I happened to open

the closet for some other reason and discove red a warm box and immediately went through

the shut down sequence to take it off line for a new power source. Several days later, the unit

was shut down again for a long weekend of downtime on a routine maintenance schedule and

upon restarting the system the hard drive would not work. I am pretty good at

backing up everything but could not find the backup disk anywhere. Panic. I am the author of a

newsletter that goes to hundreds of subscribers everyday, and the mailing list was on the dead

drive. I replaced the drive and reloaded everything but was going through sobbing spells as I

looked for solutions to recover the lost data. Data recovery companies wanted over five

thousand dollars to try to recover the data. A client of mine told me he once possessed an old

286 that required a hair dryer to get it running every time he turned it on. The fellow who had

built it for him was an IBM technician and gave him the hair dryer idea because that is what

IBM used to do to restart the drives in down machines. So on the bench machine with the drive

out where the dryer could get to it and still be hooked up, I began the process. Lo and behold,

it worked. While it was running, I downloaded all the missing data and immediately uploaded it

to the new drive. Don't laugh, I got my outcome and can now say I recovered a fully dead hard

drive with my wife's hair dryer.

From: John B.

As for me, I have had good success with this method (about 50-50). I take the drive, and

suspend it 4" over a plastic carpet tool (one of those things you see in an office to help the
