I've a hard drive that began to fail, sometimes bios recognised it and SO
began to boot, but next to it system reboots.

Now none computer find it. I'm think that hd don't spin, because i dont
listen noise.

any tool could access to hd without bios support ?

the hd is a western digital caviar 40gb ide.
 
is possible change the hd electronic board for other (same hd model)?

i want recover data and after it i will buy a new hd

You need another hard drive or another entire system with a
HDD already in it, that other HDD having enough free space
to hold all the data you need to get off of the failing
drive.

The other hard drive or entire other system is used to run
the operating system you will use to copy off the data and
your failing drive is only used passively- as storage, not
to boot the operating system.

If the bios can't detect the failing drive AND you are sure
it is the drive failing and not a bios or motherboard
problem, then no other readily available tool could do it
either as they would have to do the same thing the bios
does, communicate with the hard drive which is not
functioning correctly.

You would try to boot the system and if/when you get the HDD
to detect, you then copy off as much data as you can as it
might fail at any moment. You should refrain from trying to
use the drive at all, don't even have it powered at all,
until you have the other system or hard drive set up and
working.

You can also use a recovery operation like www.retrodata.co.uk,
the price isnt as bad as the worst of them.


If it doesnt spin up, no software can access the data.
 
I have some question about the hd electronic part:

the bios communicate with hd trough mainboard ide controller, its possible
send commands to ide controller or view the process of detection of hd?

are there cmos or flash or other rewritable chip?

Always i hd a bad hd it made a "klok noise when spin up" but make no noise.

Today i going to try put another electronic board from other hd.

thnks

Not unless you write the code to do that.

Npe.

Yes, there drive is usually flashable, or at
least has the firmware on the the platters.

Thats the drive recalibrating.
but make no noise.

Thats not usual if it doesnt spin up at all.
 
I 've changed the electronic board with positive result.
Now the hd is running and i'm copying important data to other hd, and after
it i will send the bad hd to vendor.

My hd is a western digital WD400, and in the bad board i don't see any fuse
or chip burned...my good luck is having another same model hd :)
 
Thanks for the washup, too rare in my opinion.

Yes,
Seagate, Toshiba - easily, with built in TMOS, other brands - more complex

There are serial, parallel flashes, firmware is on the platters, HDD`s
microprocessor and inside flash

??????

HDD recalibrates when powered on, later it constantly recalibrates according
to working temperature
Thats not usual if it doesnt spin up at all.

You will need to solder an adapter for monitoring through TMOS. One of many
variations of the cable:

http://hddguru.com/content/en/articles/2005.10.01-Seagate-RS-232-adapter-schematic/

Then connect via terminal program (windows hyper terminal, ZOC, st_mem,
Norton Commander, etc.)

on power on, Seagate will give you the starting log, like this:

Interface task reset
1024k x 16 buffer detected
ALPINE - 1_Disk S.15 01-16-03 11:51

Buzz - Head Mask 000F - Switch to full int.
Spin Ready
3.04 03-10-03 14:57
(P)PATA Reset
OVERLAY FAILED

and thats exaclty what the problem is - OVERLAY FAILED, so ovl needs to be
rewriten to firmware on the platter
