VERY OLD Maxtor 86480 D6 Recovery Advice

[ddrecovery]

I have a Maxtor 86480 D6 which has a burnt out PCB (client connected the power plug upside down). This model pre-dates the PC3000 manuals. I have a donor drive and have swapped the PCB but the drive clicks. Do you know if this model needs a ROM swap? (firmware on both drives ID's are the same). I have attached a picture of the board. If it does need a ROM swap, which chip is it??

I have put the donor onto PC3000 to get a feel for the drive, but many of the usual functions in the utility do not work with this model and occasionally makes the utility freeze. It could need a head swap (damaged pre-amp) but wanted to explore every avenue first.

If you apply 12V to the 5V input on an unprotected drive, then you have to wonder whether the preamp survived.

To answer your question, U303 is a Flash Memory. Searching for its part number turns up plenty of hits for the datasheet.

Thanks fzabkar
In case anyone searches for this drive model number - I completed a ROM swap this morning and the patient ROM worked on the donor drive so the ROM's are compatible on these drives (at least this one was with the same firmware). This is a preamp issue.
