Hi group,
I already scanned this ng and couldn't find a similar problem, so here
it is:
I have two WD200EB drives, one good, one faulty with data I would like
to recover but no so much that I pay $$$ to a recovery service.
Symptoms:
Repeating clicking sound as soon as the pc is turned on, even with the
data cable disconnected, and every time the drive is accessed.
After a while, using the setup hd detection, the bios detects the drive
with 0 heads, 0 sectors, 16383 cyls in CHS. It should be 16, 63, 38792.
So I tried all the following with no success:
- Swap the electronics pcb's. The good one still works, the faulty
doesn't.
- Swap machines, cables, power connectors, ...
- Used Western Digital utility, works on good, with faulty bangs out
with exception error. Too fast to read, probably division by zero
caused by 0 parameters. If so, congratulations programmer.
- Used mbrtool.exe to backup MBR from good, restore to faulty.
Read/Write error.
- Used Norton diskedit.exe on physical mode to read first sector from
good and write to faulty, sector not found message.
- Used dos debug for same purpose, no result.
- Cried for help to YOU, please help.

Thanks.

This seems unlikely to be recoverable without physocal repair.
Pay somebody that knows how to repair HDD hardware (and spent a
considerable amount of time learning it) or do without the data.

And now you know why backup is a good thing.

Never seen this one before - normally the mechanism that prevents the
r/w assembly from moving off the platters is pretty solid.

Just to clear any doubts you might have, I reassembled the broken head
assembly back on the good disk I had, on the exact position I found it.
Take a look here:
http://us.f2.yahoofs.com/bc/41d14bef_21ec/bc/photos/WD200EB.jpg?bfr.U0BBVtTO3NIC
Watch for inserting the full http address in the browser box, probably
you know this but there are people who don't.
As you can see, the part of the head assembly where the voice coil is
embedded is made of plastic and you can see it broken on the end that
was used as a limit stop.
As to my skills, I just used a trax (is this the correct name?)
screwdriver for all the screws (they all have the same size and type)
and a needle to open the heads fork to put it back on the platter.
For your information, the disk is now completely dead after the head
landed on the platter with that shriiiiinch.. noise due to a dust
particle being caught between the two.

You are very lucky that you got your data back _before_ the "shriiiiinch"
noise.

One should not count on getting away with this. Now, would you have tried
this if the data was worth $100? 1000? 10,000? 100,000? 1,000,000?

It's difficult to tell the value of the data I had on the disk but,
just to be objective, I wouldn't have tried it if it was worth more
than $300.
That's when the professional data recovery services come in, I guess.

O.k., very lucky then ;-)

Sure, if the data on such a disk is not worth much, and if there is a
spare HDD of the same model that also has no significant worth,
anybody may try this. And I agree, that if it works it is very nice.
However it may (and will sooner more than later) fail and can result
in no data recovery at all. And professional recovery from the result
of such an attempt will be very expensive.

So all of you that realy do not want to loose your data, paying for
professional recovery is far, far less risky.

All others: Give it a try ;-)
