I bought a widely-advertized Erasable-Optical drive from <deleted, send mail for details> which was touted to work on a VS-3100 SCSI. WARNING- it does not work. At all. It turns out it worked with earlier 3100's but not with recent models (the manufacturer says). Something to do with SCSI protocols. I don't want to give these guys all bad marks - they are sending me a substitue magnetic drive until the problem is solved, and I think this was as much a surprize to them as it was to me. That's why I'm leaving their name out of this note. But if you must know, send me mail. Ed Mills Harris Semi Melbourne, FL

I talked to a tech guy from American Digital Systems who suggested that I wait until the OD vendors had some experience with VMS 5.3 before buying. His explanation: there are at least 4 SCSI firmware revs in the VS3100, the ADS product works with two of them under 5.2. The SCSI firmware reports incorrect information about the optical disk. The drivers (PKN?) in 5.2 accept this info and cannot handle the disk. Ultrix drivers seem to ignore this information, and it is hoped that the 5.3 drivers will as well. If anyone knows the real story behind this, I'd love to hear it. I have racks full of software on tapes and several large chemical databases that I need to have on optical disk.
