I have an old DLT drive that is slowly going south... and a new replacement
unit does not register at the SCSI POST. Can any SCSI Guru help? (sorry for
the long winded description)
Any help would be appreciated.

Base: Computer with a SCSI controller card connected to an internal boot hard
drive, and an external Quantum DLT4000S DLT tape. The tape drive is
connected with a 1 meter (3 ft.) long cable, 68 pin SCSI connector on the
computer side and a 50 pin Centronics SCSI connector on the tape end. A 50
pin Centronic style terminator is on the unit.

1. When the system is all plugged in, the computer POSTS, the SCSI card
initiates and detects itself on SCSI ID#7, the hard drive on SCSI ID#0, and
the tape drive on SCSI ID#6. The system boots-up and everything works OK.

2. When the tape drive is unplugged from the system, the computer POSTS, the
SCSI card initiates and detects itself on SCSI ID#7, and the hard drive IS
NOT detected. The system asks for a boot diskette in drive A:.

The tape drive started to make some 'noise', so a replacement unit was
purchased: HP DLT4000D that is set to SCSI ID#5.
The new tape drive requires a cabling with a 68 pin SCSI on both ends and a
68 pin terminator, so a 2 meter (6 ft.) long cable and a terminator were
purchased.

3. When the new HP tape drive is plugged in the system, the computer POSTS,
the SCSI card initiates and detects itself on SCSI ID#7, DOES NOT detect the
hard drive, and DOES NOT detect the new tape drive. The system asks for a
boot diskette in drive A:.
After replacing the new terminator wirh the old Quantum drive and its
terminator: same result.

4. When the new HP tape drive is plugged in a different system (System 2),
the computer POSTS, the SCSI card initiates and detects itself on SCSI ID#7,
DOES NOT detect new tape drive and then boots-up and hangs at the splash
screen.

5. When the new HP tape drive is plugged in a different system (System 3)
using a different cable (50 pin to 68 pin), the computer POSTS, the SCSI card
initiates and detects itself on SCSI ID#7, DOES NOT detect new tape drive and
then boots-up. The operating system deos not see the tape drive.

You bought a High Voltage Differential tape drive.
It's not compatible with any current SCSI
You need a HVD SCSI card for it like Adaptec 2944.
