Maxtor drives tend to accept PCB swaps, making data recovery when it's only a burnt chip (ST 2DPS20V, in this case) nearly effortless.
I had some worthwhile* data in need of recovery.
In 2009, 80gb donor drives were still expensive ($75 to $100).
Now, they're under $30 on ebay (the one that worked for me was $26.99 with shipping.)
See references for what's (probably) needed for a donor match.
PCBs and Shells
After switching boards, I simply booted Hiren's on a diag system and copied the data off to a network share.
If you find yourself in similar circumstances, perhaps consider this much cheaper (and brainlessly easy) route before sending it into the pros.
