1. what is the rom? 01 or 02 Please look photo. pcb donor is compatible? (=model= fw=p/n)

100536501

(=model= fw=p/n)pcb bad 100536501 rev A = pcb donor. different processor

2. Hard drive failure: I had purchased a Seagate Barracuda 1TB drive last June which had functioned perfect until this Tueday – the drive had initially displayed a blinking light, with no recognition in Windows or the system BIOS. However, after removing the hard drive enclosure and connecting it to my motherboard via a SATA data/power cable, it had emitted a crackling-like sound, with some burning smell and wasn’t recognized by the system BIOS either. I’m assuming that the drive’s PCB board is damaged and was wondering of whether a replacement is possible – I had a lot of very important data stored on it (and in before "should have backed it up", I was about to purchase another 1TB drive and haven’t been able to acquire one since to back up the data stored on this drive).

The drive is a Seagate Barracuda 7200.12 1TB external HDD with the PCB ID 100536501 REV A

3. Seagate Barracuda burnt circuit board – DIY Fix?

This is a friends external Seagate drive that stopped working. I’ve removed the drive from it’s enclosure and removed the circuit board. On inspection the circuit has been burnt below the SATA power input.
See attached Pics:
As you can see two small transistor fuses ( I think thats what they were ) are totally destroyed. The two TVS diodes are intact but I think one of them is dead. The left diode gives a multimeter reading on the 2000 OHM setting of 481 with no buzzer alarm the right diode gives a reading of 001 with alarm sounding.
My question is can I somehow bypass the fuses if thats what they are?
Can I make some kind of temp repair, so the data can be backed up?
