good evening ,

i had this maxtor diamond max 21 ,,st3250310as with fried pcb ..

i found a donor drive seagate 7200.10 st3250310as

the patient ( and the donor) doesn't seem to have a flash component to be transferred , when the pcbs are swapped , the patient identify correctly , but at very high latency , and imaging is almost way to slow ..

any ideas ?

the photo is taken for the donor PCb , the patient one is just identical , but with burn spot near the crystal , and no way to reuse it ..

thank you

Try cleaning the pcb.
HSA and spindle contacts seem to be full of oxidation, you can use a pencil eraser to clean those.

Unless there is a hole in the PCB, then it should be repairable ... if the damage is what I think it is.

tried cleaning up the contacts , same effect ..

acutally the burn mark is just like the one in your photo Frank , who r u ? the PCBs God ?

but the MCU has a burn mark too , + user "that i think never used a hot air soldering system " has removed the regulator near the cach chip ... the pcb is a total wast to try to repair ..

any ideas ? thank you very much
