Tryed to directly change serial with BAD results...

November 10th, 2009, 10:19

Maxtor DiamondMax Plus 8 40Gb [6E040L0 - NAR61590].

With HDD Repair 2.0 I dumped and modified 4 modules in which I found the HD serial:

Begin UBA 45a2
Begin UBA 8 (there the serial bytes are swapped)
Begin UBA 2bf
Begin UBA 4660 (there the serial bytes are swapped)

The modification was ONLY in 2 bytes of the serial, to see if that software was capable of changing the serial itself.
After each change I send Disk ID command but the serial was always the original.... while dumping the modules I modified it was modified !

After a few time (1-2 minutes) pc hanged and then the hdd is no more recognized by the pc even at the startup...

Is there any CRC control after changing serials in maxtors ?

Any way to recover the hdd considering that it is no more recognized by the pc ?

Thank you in advance !

You simply don't know how Maxtor firmware works. Editing modules without arranging checksum will render the module corrupted.
If you want to restore functionality of the drive you are working on, restart it SAFELY ( 8) ) and revert the changes done. Can't tell you more.

Can I only ask you WHICH module is the "incriminated" one ? 8 o 4660 ?

0008 (0001 in length) : AKA "DISK"

Thank you both ! So 4660 is the "backup".

A problem:
the pc won't boot with that bad-modified hd attached... is it safe to connect IDE cable AFTER windows start and re-try to modify the module with HDD Repair 2.0 ?

You asked about CRC - you got answer about checksum,
This "DISK" module (like most, but not all) uses checksum.

Google should help you to find method of calculating checksum for this drive, I think.

Then you can change Serial Number to anything suitable, but you must then
do a recalculation of the checksum for this "DISK" module, then the drive will work just fine
with modified S/N.
