Hey guys, my 160 GB SATA Hard Disk is not working . It just happened
when i connected to older
PC due to low watt from SMPS, than a Brilliant White Smoke came,
immediately i switched off the power supply. when i check the Hard
Disk the Capacitor has Burnt, Assuming it should not cause any damage
to the hard disk. Now i want that PCB of 160 GB Seagate Hard Disk in
order to replace the burnt one . Can you help me ? where do i get that
PCB ? Please............

Not an option, there is information about the drive platters, heads,
etc, stored on NVRAM on the card. Any other card won't hve the right
information.

Why not if the heads and the platters are the same which they should be in
an identical drive. Critical data is stored on an engineering track on the
media itself, not nvram.

Any specific drive is never generic. It, and all others made in the
same batch, with exactly the same hardware, were caused to scan
themselves and note each bad physical spot on each platter. The number
of such spots is sometimes zero, more often not. Depending on the
specific manufacturer, this info is stored in NVRam on the PCB
(possibly on the disk itself, somewhere, as well). The bad physical
spots are mapped-around in the drive's firmware so that normal disk I-
O does not attempt to use them.

The (**VERY**) expensive data recovery services have created hardware
and software capable of getting around these drive-unique
characteristics for possibly thousands of sets of drive hardware (and
production block changes). That is why they are expensive. It may be
worth your time to substitute a new drive PCB and try it...but don't
get your hopes up.

Good luck!
