I keep my PC on and booted 100% of the time. After reading the above postings I thought that I could just do some of the pallitives mentioned. In particular I thought I could use some Gunslick, a conductive graphite based grease from Outers. So I took the drive out and much to my surprise the whole tab had worn off and disintigrated. The story has a happy ending, however, I had a spare 20 MB Miniscribe. Right now I'm looking for the newest hot ticket in half-height, ST506, 5 1/4" drives. I've heard good things about the Tandon 740 a 30msec, 40MB drive. Think I'll get a few. Joseph L. Wood, III AT&T Information Systems Laboratories, Middletown (201) 957-5475 titania!jlw
