Fujitsu MK2714TAM 1Gb I have eats 5V 450 mA. Not too bad. But it's a sick drive (RMA'ing it.) My old Toshiba MK1722 130 Mb drive OTOH eats 5V 700 mA. Ack! I've noticed that many laptop web sites have no easy guide to average power used by their drives, "Oh, you'll just cope with what we give you if you don't know any better", I guess. I know one other thing on drives; Some Maxtor drives (at least the 3.5" units, probably other manufacturers do this too) use conductive plastic contact strips to connect data from the Drive's PC Board to the drive heads & etc inside the drive. A friend who repairs drives just detests those drives, says the conductive plastic tends to become non-conductive with age & thus the drive fails prematurely - and he can't fix it. (Anyone know how to fix said plastic strips? That knowledge would give me temporary godlethood status with this guy <G>) Maxtor used to use conductive plastic for drive POWER connectors as well, but quit (high failure rate, maybe?) I've tended to stay with drives that have a ribbon or metallic-contact socket connection, since talking to him. I've had to pull PCB's & clean contacts twice total (about to do so for a friend's 1Gb FH SCSI drive, but that doesn't count! <G>) Mark Willis
