e Hi, I'm running out of space on my TP750C... Big Blue's prices disqualifies them, so... I know that some of you have put in IBM-OEM drives, how do they work? Can I put a 540 MB drive in my machine? And, do you have some info like part # and prices? (I also might be interested in buying a drive 2nd hand... >170, if the price is right..) Regards, Erik
