It had begun to vibrate badly a few months ago. However, Jasmine repaired it promptly at no charge. It was only 15 months old, and still under warranty. Thus, we are very pleased with their service. However, in the past we, too, have had several instances where we lost the SCSI mapping. These problems occurred when the disk became nearly filled with data. We maintain two 40 MB "hardware" partitions, using the Jasmine Driveware software. One might argue that our disk was clearly faulty, and that these lost SCSI mapping problems can be blamed on intrinsic weaknesses with our particular unit. Yet, the SCSI problems occurred twice before the vibrations became noticeable. Your tale of woe sounds so familiar, that I begin to worry about a recurrence of the problems. Even when one maintains backups, it can be very painful and time consuming to restore 80 MB. Has anyone else experienced similar problems ? Is this a known disease, with a documented cure ? Thanks for any information... Dave Blockus dxbra@slacvm.slac.stanford.edu
