I'd look for the most trivial reasons first:
o Did you check if the drive's dip switches are in the positions
   recommended for your OS (I told you already)?
o Apply a cleaning cartridge twice or thrice.
o Try different tape media.
o Check proper termination at the "outer" end of
   your SCSI bus (no termination stuff at the drive itself
   is necessary)
o check if your 50-68 adapter is appropriate,
   iirc when going from "wide" (that's presumably what
   your controller is) to "narrow" (your drive) it must
   terminate the "upper 8 bits".
   You may also consider getting an 68-pin DDS-4 instead.
o Consider the possibility that your drive is simply broken.
   When I purchase cheap used DDS drives I'm prepared to
   trash about half of them immediately.
o Contact your HP representative for a copy of their brochure:
   "Success with DDS Media", HP Part No. C1500-90911 June 1993
