'[OT]: Failed HD Recovery'

Preface: I'm concerned of the leaving of James Newton and all that lead
to that unfortunate decision. I wish things could be different but
accept his need for some separation. Good luck, James. I hope your leave
isn't permanent.

My Problem: My pc was unable to boot from an older Western Digital hard
drive. I have replaced it and reloaded the OS, but I need some of the
data on the old. <grin>

I've tried to switch it as a slave to the now current boot disk, but
the system doesn't "see" it as a drive. Even tried a WD utility and it
doesn't see it.

This happened suddenly. One Monday morning it would not boot. The drive
does spin up.

Anyone with some insight for me to try recovery myself??

Peter

Get it from your backups.

Does the BIOS see it?  Have you checked both ends of the
interface cable?  Have you tried the drive in master mode
on a different (I assume IDE) interface card?  Have you
checked +5V & +12V levels at the drive power connector?

It's a failure mode I've seen before.  Interface portion of
drive has failed while motor controller is working OK.  It
is probably just a failed drive.

> Anyone with some insight for me to try recovery myself??

If the motor spins up the platters and it sounds "normal",
then it might just be the electronics card.  Get another
identical model drive (that's working) and swap controller
cards between the two drives.  It will void any warranty
but you _might_ be able to recover your data.

Or contract with a data recovery company to try and get
back your data (but that's expensive).

Been there...  recently, in fact, but with SCSI disks (which I am now
convinced are the work of the Devil, by the way).

That sounds bad, like a servo or board failure.  Do you have access to an
identical drive from which you can swap the logic board?  I've done that
on older drives.  It seems the newer the drive the slimmer your chances
for success, though.

-OT- I don't like western digital.  If it's older than 3 years, toss it.
-OT-

If the drive isn't clicking, and you've made certian that bios does not
recognize it, then you try changing the controller board with an
identical drive, or send it to a hard drive recovery place.  If it is
the controller board they would charge you less than $1000 to recover
much of the data.  If it is the servo or a portion of the drive interior
to the case, you can expect a fee of $2000 to $5000.

Hope your data isn't worth that much.  If it was, you'd have backed it
up, right?  :-o

Helllo:

Another thing to try is to power up the drive and let it run for a day or so.
Some of the older drives had poor temperature stability and would not work when
cold.
I have seen people put blankets over their older computers to keep them from
getting too cold!

73,

Peter, when u re-configured your original disk as a slave (presumably using
the on-board jumpers), did you redifine it in the BIOS setup? Not all
motherboards default to autodetect (some default to no drive)

Another possibility, althogh more remote: your new boot disk is now
configured for primary master. But, it might also have a jumper to say
'slave present' on the IDE chain.

Regards,

Anand

Western Digital are bad....

My friend had a 20 gig and the head froze...
It wouldnt spin, so we ripped of the cover and tried to spin the
platters....
It was froze solid..

I have a WD 10 gig and it makes clicking noises and says when its in my new
PC: "HD Error: SMART Capable drive detects imminent failure."

I use it to store all my data (~3 gig)

Here's some feedback for those interested on my HD problem. I appreciate
your interest and help.

The OS is WIN95 w/ SR2. The MB supports autodetect and is currently
supporting a new HD combination of a master (jumper set) and a slave
drive, also jumper set, all connected on a fresh IDE cable. This
configuration works fine.

My testing used the above as a base setup into which I switched the
slave units. The old, failed WD is not recognized during boot in Win95,
nor when booting from a utility floppy and using FDisk.

Feedback to your ideas:
1. I don't have a similar HD to swap boards. The HD is dated 1995.
2. The MB autodetects, so I didn't change CMOS settings by running
Setup.
3. Only one IDE cable is used, a new one now.
4. Mentioned by Brooke, the unit temperature may be noteworthy. Fact,
the pc would
not boot on a Monday morning. Weekends here are sometimes very cool in
the office. Therefor, the pc was the coldest, being off for 2 days, when
I turned it on and it would not boot then.

Right now I heating up the old HD, using the heat from the top on the
monitor, and will leave it there all day. In the evening I'll try the
hotter drive as I did before.

Thanks again, Peter

I must have deleted the first post of this, but I have seen the problem
before in Western Digital Cavier drives. When cold, the hard drive would
spin up making a chimmering noise and would not be recognized as
being a boot device. When the hard drive warmed up to about 85 degrees
Fahrenheit then the computer could be rebooted and the drive would be
recognized. Once recognized I ran all sorts of utilities on it and they all
said that the drive was fine - but it still wouldn't work when it was cold.
I had a spare drive so I replaced it, but I kept the drive to play with when
I had some time.

Eventually I found that some of the traces on the controller board didn't
make full contact when the board temperature was below 80 degrees.
And since I was especially bored on that rainy day, I tacked wirewrap
wire between the traces and the controller chip pins that were affected
and it worked even when cold. Of course the wirewrap fell off a week later
shorting against the controller chip pins and cooking the traces.

My best advice would be to warm the drive up, copy all of the info off of it,
and throw the drive away (or salvage parts off of it :-) ).

Here's the "post mortem" on that &@%$# failed WD 21000 Caviar HD I've
been talking about. I think it's sick beyond help. I'm stopping for
now.

Today, as I said I'd do, I heated the drive for 7 hours on top of my
monitor. Next I switched it into my Win95 SR2 system as a slave drive
and boot to the recovery floppy. To my excitement it and the master were
recognized in POST. Then quick disappointment. I try the dir D:\ cmd and
it doesn't see a D:. I run the WD Diag pgm. It sees the slave but errors
on an extended test, rasing two dif. error codes that both say in effect
"drive shot, contact WD."

I repeated the above but using it as a single master, same.

Oh well .... Unless I find another like drive for swapping the
electronics, I'm dun w/ this turkey.

Cheers, Peter

Well, look on the bright side.  When yo're done taking out your
frustrations on it, you'll have two REALLY STRONG magnets, good for
holding chuck keys to drill presses and stuff like that...  oops!!  Wrong
thread, sorry!  8-)
