- We recently installed a 1.6 GB Seagate drive on the external
- SCSI connector of an Indigo XS-24 (IRIX 4.0.5). The hardware
- inventory is as follows:
-
- 1 33 MHZ IP12 Processor
- FPU: MIPS R2010A/R3010 VLSI Floating Point Chip Revision: 4.0
- CPU: MIPS R2000A/R3000 Processor Chip Revision: 3.0
- On-board serial ports: 2
- Data cache size: 32 Kbytes
- Instruction cache size: 32 Kbytes
- Main memory size: 16 Mbytes
- Integral Ethernet: ec0, version 0
- Tape drive: unit 7 on SCSI controller 0: QIC 150
- CDROM: unit 6 on SCSI controller 0
- Disk drive: unit 5 on SCSI controller 0
- Disk drive: unit 4 on SCSI controller 0 <<<<<--- 1.6 GB Seagate
- Tape drive: unit 3 on SCSI controller 0: DAT
- Disk drive: unit 1 on SCSI controller 0
- Integral SCSI controller 0: Version WD33C93A, revision 9
- Iris Audio Processor, rev 3
- Graphics board: GR2-XS24 with Z-buffer

- When the machine boots up it gives the following error message:
-
- sc0,4,0: cmd=0x1b timeout after 60 sec. Resetting SCSI Bus
- SCSI device/cable diagnostic * FAILED *
-
- If you continue on with the start-up, the computer seems to
- be fine. At least the 1.6 Gb disk seems to work alright. (see below).
-
- I tried fiddling with the Motor On jumpers -- didn't seem to help
- either way (on or off). The drive is NOT terminated so I removed
- the "tp" jumpers.
-
- We are also have some problems with the QIC and DAT tape drives
- on this machine -- they tend to quit prematurely with
- unrecoverable errors. Sometimes they report I/O errors. The errors
- _seem_ to be more numerous since we installed the Seagate. Is
- is possible for the disk to work fine but screw up the tape drives?
-
-
- Senseman's First Rule of Computers says that 99% of all computer
- hardware errors is due to a bad cable -- and I suspect that
- this is the most likely candidate here. However, before I go
- into the cable making business, I wanted to know if anyone else
- might had seen this problem with the 1.6 GB Seagate drive before.
- I had a 140 Toshiba drive in there previously and didn't experience
- any problems with it so maybe the cable not bad?
-
- Thanks.
