Its an IC35L The site has a nice util called the drive fitness test :- http://www.hitachigst.com/hdd/support/download.htm Fits on a floppy and tests your SCSI drive. I did this because my supplier told me to ; I was complaining about the noise :) They said - run this thoro - if it doesnt throw up any errors - your fine ! They also put this :- (FYI, you'll normally find ~1% of a disk is actually dead from the factory, but that there's actually 109% of the available disk space there. Over time, the drive will invisibly map bad sectors to unalocated ones (called spanning sectors). when you run out of spanning sectors, (ie, its spanned out) THEN it's time for a new one, as that's normally the point at which the drive packs up) Anyways, mine seems to have survived the minor drop without any probs :) Crazy to think ~ VLSI has come so far yet we are all so dependant on spinning discs motors and magnets :) Custom PC North West Open Source Solutions http://www.cpcnw.co.uk
