Great. I look forward to seeing it. I am tracking down a problem now where I can't do alot of disk activity on my new DEC scsi drive when the HP CD-R drive is plugged in. I unplugged it from the scsi bus and everything is fine. Plugging in and unplugging my external cdrom and zip drive doesn't change anything. Keep in mind that there is no activity on the HP CD-R side of things. This is really strange... I think I am going to have to plug in an Adaptec 1542 and use that for the HP CD-R drive. Here's what happened when I tried to copy my entire /user directory (600M) into a partiton on the 2 gig DEC drive: First, here's the stuff on my scsi bus.

I filled the whole 2.1 gig drive up fine when I unplugged the CD-R and rebooted... Any ideas? Fred.
