Greg, The two 4-mm drives I have are Connor DDS-2 drives, and they're probably about 2 years old. Neither gets a lot of use. I clean them more often than the cleaning light comes on (which is usually after an older tape gets read). Is it "worth" overhauling the DDS-2 drives? I've avoided 8mm because I'm not fond of the wear caused by helical scanning. If this is true, I figure my choices are: - Overhaul my existing drives - get new 4mm drives - get DLT drives (*Much* more expensive) If I could find a writable DVD drive I'd consider that as my backup medium. CDRoms at 600M are just too small. Suggestions? The "second" machine (ah controller and my primary amanda server) is where I first noticed the problem. Lately, certain filesystems refuse to be backed up and end up on the holding disk, and I cannot amflush them to tape. I noticed a rare disk sector I/O problem, and reformatted the disk. Even so, when I would try to read or write a tape on this system, I would frequently get a system SCSI lockup that required hitting the reset button. This is when I tried reading the tape on the "first" system (bt controller) and eventually discovered that I had to do this from vt0 to see that the kernel was trapping to the debugger. On the second machine (ah controller) I just get SCSI bus lockups, but no debugger traps (and when this happens I can't use the vulcan death grip to get in to the debugger).
