External Flash Rom-Pin Damaged

[datacare]

While desoldering External Flash ROM there is one pin got damaged, anybody help in this case how to recover the data from that hard disk without Original Flash ROM

MODEL:-ST9320325AS
FIRMWARE:-0002BSM1

It's F3 architecture, so very very difficult indeed

thank you very much for your quick reply

Can you post a picture of the damaged rom?

Not all pins need to be present in order to read the flash memory.

In case the missing pin is a mandatory one:

I have seen emergency repairs been done by replacing a missing pin with fine gauge wire wrap wire. Takes good eye sight and a steady hand while soldering. Probably works best for pins at the end of a row. In case a tiny piece of plastic has to be milled away.

Have to admit I never used that technique myself. I would have started out by trying to read the chip with an Eprom programmer... probably sacrificing the test clip while attempting to get a connection to the missing pin.

I did this allready with good success. Microscope is neccessary.

I had to do this last week, one leg of the ROM chip snapped off when removing it from patient PCB. I transferred it to donor PCB and had to fiddle for about an hour to build up my own 'leg'. I actually used a leg off an old ROM chip I had lying around, worked well.
