Dear Sirs,
my Seagate DiamondMAX 21 - STM3250820A PCB has gone, as you can see in the attached pictures.
Luckily I have another identical HDD and I tried PCB swap, but with no luck: BIOS won't recognize it. I hear the HDD spinning, but....
I would like to know:
- Should I swap ROM too?
- Which of 8-pin IC is in PCB?
- A "live PCB swap" could solve the problem?
- Is there something other to do (software mode) to make my hard disk be recognized like "HDD Scan and Restoration Program", BIOS indipendent?

Thank you alot in advance for your precious time you will spend to help me.

Best regards

Alex

BAD HDD




GOOD HDD

I can't see its part number, but the 8-pin chip near the bottom LH corner of the MCU appears to be the serial EEPROM. Does the part number start with 25P?

First of all thank you for your help and for your interest in my problem.
The chip in question have this number, if I'm not wrong: 25P0SVP.

First of all thank you for your help and for your interest in my problem.
The 8-pin chip, if i'm not wrong, has this serial number: 25P0SVP.

That's an M25P05VP "512 Kbit, Low Voltage, Serial Flash Memory" by ST Microelectronics:

According to you could I try swapping the 8-pin IC?

Hello
Unfortunately I damaged my DiamondMax HDD. Two little components on the controller are destroyed, the little round one in the top center and about 4cm right of it, the other round, small device.
I guess it is possible to repair by replacing it with new ones, but I need to know the kind of device.

does anybody can help me?
thanks a lot

Can you upload a detailed photo?
