  Hi!  I checked the Hardware HOWTO at linuxdoc.org, and (in section 15)
  it doesn't list HP Colorado 5GB as a drive supported by ide-tape.

  (Then again, that HOWTO does make contradictory claims (in sections 15
  and apendix C) about what parallel port drives are supported.
  Interestingly, my tape drive probably would be usable if only it was
  parallel instead of ATAPI interfaced...sigh...)

  But it "mostly works."  Here are the results I have so far.
  The kernel can see my tape drive; here's what dmesg says:

hdd: HP COLORADO 5GB, ATAPI TAPE drive

  When I try "mt -f /dev/nht0 status," that outputs

SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 512 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (0):

  and adds to dmesg:

ide-tape: hdd <-> ht0: HP COLORADO 5GB rev 2.05
ide-tape: hdd: overriding capabilities->speed (assuming 650KB/sec)
ide-tape: hdd: overriding capabilities->max_speed (assuming 650KB/sec)
ide-tape: hdd <-> ht0: 650KBps, 16*32kB buffer, 6336kB pipeline, 100ms tDSC, DMA
ide-tape: Reached idetape_chrdev_open

  Unfortunately, it seems that the tape drive is write-only.  That is,
  while stuff like "mt -f /dev/nht0 rewind" and "tar cf /dev/nht0 foo"
  seem to work just fine, "tar xf /dev/nht0" writes to stderr

tar: /dev/nht0: Cannot read: Input/output error
tar: At beginning of tape, quitting now
tar: Error is not recoverable: exiting now

  and adds to dmesg:

ide-tape: Reached idetape_chrdev_open
ide-tape: ht0: I/O error, pc =  8, key =  5, asc = 2c, ascq =  0

  Help is appreciated!  - Carl

If you really really want to we can try and hack together a driver for it.
It would not be high on my fun list but I would be willing to try.
