Re: ide tape drive that thinks its a hard drive

[Danny Sauer <sauer@cloudmaster.com>]

Just out of curiosity, have you tried using /dev/ht0 anyway?

What about treating it as a removable device?  "taper -T", etc :)

Look in ide.c and see if maybe there's an option to force that
device to be a tape drive.  I know you can do "hdc=cdrom", but
I don't think that works for tapes...  When I looked, I didn't see anything
in ide.c or ide-tape.c, but maybe you'll not be reading it as you fall
asleep at the keyboard. ;)

Have you tried ide-scsi emulation for that tape drive?

Oh, and look at the actual /dev/hdc and /dev/ht0 files, making sure the
major and minor numbers are right.  Mine are
brw-rw----   1 root     disk      22,   0 Mar 11 04:12 /dev/hdc
crw-------   1 root     root      37,   0 Mar 11 04:12 /dev/ht0

--Danny, just some stuff to think about
