The ID selectors on external enclosures are normally connected to jumper banks on the drive itself. Possibly the Zip drive could be changed to a different ID that way. You should certainly be able to change the hard drive's ID by locating its jumpers. If you need spare jumpers, they are often included in computer-builders' toolkit sets, along with spare screws, washers and standoffs. I have such a set made by Belkin, and I believe iFixIt also sells some. You should also be aware that SCSI buses are typically very sensitive to correct termination. If you don't have a terminator on your Zip drive, that's a really good candidate for why it doesn't work, regardless of ID settings. Some drives have a termination switch or jumper built in, but some need a dongle attached to the bus itself. - Jonathan Morton -- -- ----- You received this message because you are a member of the Vintage Macs group.
