	Mine was the "D3000000" serial, not the "M0000000000000000000" serial. 
and the drives are not 100% identical, tho they are the same capacity, 
hooked to the same PDC20265 IDE bus, on a ASUS A7V266-E.

	I'd submit the /proc/ide/hd[gh]/identify but atm /proc seems to be 
blocking on that request. I'd submitted it before anyway.

	The drives worked previously before the ide-probe patch, and have not 
been a problem before. and as I believe they only have a 1 year Maxtor 
warranty, i'm not sure i can RMA them, tho i'll keep it in mind.

	Well... if i can't RMA them, and I do replace them, I offer to send 
them to you via UPS or FedEx.
