Please CC me, thank you.
I can write just fine to the tape, but reading gives me the following
error:
# tar -tvf /dev/ht0
ide-tape: ht0: I/O error, pc = 8, key = 5, asc = 2c, ascq = 0
A search on deja.com shows that I am not the only one to have
experienced this and that it did not occur with previous versions of
ide-tape.c. The same error occurs with a non-modular kernel build.
The machine is a i386 redhat 7.0, kernel compiled with egcs 1.1.2.

I experience the same with OnStream DI30 - but these errors occure in 2.2.17 as
well. In my oppinion they show up in fewer cases with 2.4-test10.
The error is not quite"stable" because it occures on different tape positions
(filenames) when I retension the tape three aor four times befor writing to it.
I checked the tapes on a Windows machine and they seem to be o.k..

I reported this a few weeks ago or so, it seems that HP 7/14's are not exactly
standard. First is the proprietory tape size. Second is that the drive doesn't
support locking the tape in, but reports it as possible. At least, that's what i
gather from Jens's posting.
To be honest, I'm not sure the drives are worth fixing <grin> Unreliable media,
unreliable tape drives. I've got two dead out of 10, in under a year. And half a
dozen tapes or so. Plus, under 2.2.17+ide, the tape drive wouldn't restore tapes.
Something weird about the tape drive again. Had to boot up under plain 2.2.17 to
read my tapes.

I'm very much interested in what is the cause for this error.

In my case the driver tries some error-recovery three or four times before it
gives up.
On of the problems is - that these errors occure after having written several
GB to the tape - and that takes some hours. It also happend that with a tar
-cvM the first tape was ok but the second was unreadeable.
