So this was a performance raid, not a backup raid?

Music and Anime? Lol. No wonder you're trying to recover it all.=20 I'd suggest a data recovery company, all the same, before you damage your computer completely. And maybe consider using e.g. a backup - two drives; while you have to store data twice, at least if one fails, you'll have a backup [how in the world did you end up with two drives dead anyways?!?]. > Similar drive, if it'd work.

You'll be hard pressed to find a e-bay listing that lists the PCBs and Firmware, per the components, though? *shrugs* --=20 ~Mike - Just my two cents - No man is an island, and no man is unable.
