Hi All,

I have recently had a couple of Hitachi Deskstar hard drives go bad on
me. I'm just wondering if anyone else has had symptoms like these and
can shed any light on what my chances are of getting any data
recovered!

When powered up, both drives emit a strange beeping sequence, please
visit the following URL to listen as its quite a bizzarre sound (not
the usual clunks or grinding as with most HD faults I've seen):

http://media.putfile.com/Hitachi-Deskstar-Hard-Drive-Fault

Both drives produce this noise for around one minute then it stops.
Not sure if the drive powers down at this stage or not, I can't hear
or feel any movement.

The drives are both 500GB IDE 3.5" 7,200RPM Models, model number:
HDT725050VLAT80 and were manufactured in Aug 2007.

They were installed in a NAS device, see the following link:
http://svp.co.uk/product/dual_hdd_networked_attached_storage_(ide)_5707

I have downloaded and run the Hitachi Drive Fitness Test by plugging
the drives into a PC, but neither BIOS or the DFT recognise the
drives.

Has anyone had a fault like this before? Anyone managed to get their
data back? I have considered using a professional data recovery
company but could do with any comments/help before I commit to going
down that rather costly road. Suggestions on tools/techniques to
recover data?

Any help appreciated!!

Thanks,

Al.

Hi Paul,

Thanks for your comments.

Apologies for the crappy quality of the recording, the only thing I
had to hand was a very cheap microphone that came with my sat nav. It
gives you an impression of what the sound is though!!

Couldn't access the first URL you posted in reply by the way, access
denied message??

I have just tried what you said, no spinup sound that I can hear of,
the only (small) vibration seems to be what ever is causing the lower
toned of the two noises.

Ranging from £200GBP to £7,000GBP from the ones I've requested an
initial quote off!!

I think it was a power surge although the nas device was plugged into
a surge protector so that *should* have caught it before it got to the
device.

That was my first thought, no obvious damage to ICs and no odd smells
either.

Thanks for your help Paul, you've given me some good background to
search on there.

~AlicGinnis~,

Haha I was wondering when the freezer method would come up!! Have you
had first hand experience of this working? I always considered it to
be an old wife's tale!

That said, I may try it once all other avenues have been exhausted!!

On the gmail comment, I have all my mail and contacts on gmail
luckily, it was mostly music and photos that were on the drive. I may
have to upload the photos to picassa though should I ever get them
back!! The cloud is the future!
