I'm running Debian 2.2, tar (GNU tar) 1.13.17. Hardware is a celeron 300, Abit BH6, but repeats itself on all hardware i've tested(old dataexpert 8551/8661's, abit be6, some via686a box at home, gigabyte mb's, you name it) I'm currently running 2.4.0test10, running backups onto an IDE HP 7/14 gb drive. Using tar -cpvf /dev/ht0 myfiles backs up fine, no errors. But.. promise:~# tar -tf /dev/ht0 tar: /dev/ht0: Cannot read: Input/output error tar: At beginning of tape, quitting now tar: Error is not recoverable: exiting now and from dmesg: ide-tape: ht0: I/O error, pc = 1e, key = 5, asc = 20, ascq = 0 ide-tape: ht0: I/O error, pc = 8, key = 5, asc = 2c, ascq = 0 ide-tape: ht0: I/O error, pc = 1e, key = 5, asc = 20, ascq = 0 (normal, i get those cause of the lock drive/unlock drive, which the drive doesn't support) If i bounce back to 2.2.17(18-18 as well), and do the exact same command, I can read my tapes again. But I lose support for the Promise Ultra/66 in the machine. So. I go back to 2.2.17, put in the ide patches. I can't read my tapes again. Take out the patches. Tapes restore fine. So I'm wondering what changed with Andre's patches, and also with 2.4.x? I also ran into the same issues, back when i was playing with 2.2.17, using taper 6.9b, leading me to suspect it's not tar's fault. Just tried dump, aside from it not agreeing with my /dev/md0 device, it backs up fine, can't restore. I get the same results with a Seagate IDE 10/20 drive. ide-tape is compiled as a module, but IIRC it does the same behaviour as built in. Yes, the proper solution is buy a DDS-3 drive and a handful of tapes. But my cheap employer doesn't want to spend the money to do it right.
