<< ... I checked the termination and cables on the chain and 250 Zip one more time. Since the drive was the last in the chain, the slider switch on the back had been moved to termination. The slider is small and hard to get to and I had changed it when re-arranging my scsi chain and checking addresses in an attempt to make things work. Apparently the switch was not moved to the full extent of its travel. Once I did this with the help of a pen, the Zip drive worked with absolutely no problems! No more problems burning CD's either. The main thing I wanted to share is to use the rule of Parsimony...that is, always do the simple things first when attempting to solve a problem. Works for me. >> Usually, the internal CD-ROM, which is SCSI ID 3, is the drive which is terminated at the factory. It is a bad thing not to terminate at least one drive. It is a very bad thing to terminate two drives. The SCSI chip is only designed to "sink" 48 milliamps, and that is about the load presented by two terminators ... the one at the "host", which is always required, and the one at the farthest "target", which is also required. It is better to terminate an intermediate target, such as the internal CD-ROM, than it is to double terminate the SCSI bus (thereby presenting THREE terminators to the SCSI chip). -- G-List is sponsored by <http://lowendmac.com/> and...
