Successfully replaced PCB, but one problem remains

[ranman]

All,

I had a visibly burnt out PCB on a 300 GB Seagate drive as a result of a power supply gone bad. The good news is that I was able to find a perfect match to replace the PCB (Part Number, firmware, model, etc). I installed the PCB and the drive is now detected by my BIOS and OS. I can even backup the drive using Ghost and run Seatools on it to look at the drive information.

However, I can not access the file system. When I try to open the drive in Windows Explorer, I get a "the parameter is incorrect" error message. When looking at the drive in Disk Manager it shows multiple partitions on the drive, but I did not have multiple partitions. Is it possible that the new PCB came from a drive with multiple partitions (is that information even stored on the PCB board? Is there anything else I can check? After looking for 6 months for the PCB, I am oh so close. Any help would be appreciated.

You need to swap the eeprom chip as well.

Is there any alternative? The eeprom was damaged on my old PCB. Now that the drive is detected, will some software based restoration programs work?

Answer to the last question : I don't think so.

Answer to the first question : yes, there's a way

If disk is identified correctly in BIOS, does MHDD scan disk with grey blocks? If so then simple DR software should be able to access and recover your data, then you can either format the disk to use again, or replace it.
