I don't have time to investigate the status output in detail, but at first glance the output looks consistent with hardware failure. I've had this so many times with tape drives, in particular DDS, that I have given up using them altogether: not a single one survived its guarantee period. If it's not the drive, it could be the tape, though I've seen far fewer problems in this area. Does this drive (and tape) work in other systems? I don't think it's termination; you say you only see the errors during reading, and that doesn't fit. What does the drive do when you try to read it? A lot of back-and-forth is usually an indication of hardware read errors. Greg -- When replying to this message, please copy the original recipients.
