Okay...you all saw my diagrams of my A4000 Power Tower MKII and its
SCSI setup with the new Compaq hard drive I put in it.
A very brief recap:
- As per the recommendation of many of you, I added SCSI-3 terminators
to both ends of the SCSI chain. Didn't work. Couldn't boot at all.
- SCSI chain: internal active terminator --> Cyberstorm PPC [DCE, not
phase5] --> hard drive --> unused port --> unused port --> external Zip
100 --> external Yamaha CD burner --> external active SCSI-3
terminator.
Now...a few of you suggested that I set the "force single-ended mode"
jumper. I hadn't done that the last time I posted about my SCSI
troubles. Soooooooo, I did it, and here's the result:
- Nothing.
- Removed the internal terminator, and....ALMOST nothing! Here's what
happened:
Please keep in mind that the following happened both with the hard
drive was on the SCSI by itself as well as when the SCSI setup had the
other two devices. If I enabled "force single-ended mode" and removed
the internal terminator, the drive would spin for about 30 seconds,
stop, and then the Amiga would continue through the boot process.
Excellent! Except...the "setpatch" command in the startup-sequence of
course would reboot the machine. Upon the warm restart, nothing would
happen. The SCSI drive started to spin and wouldn't stop at all. [The
activity light remained on, and I heard the heads clicking and whirring
as if they were being accessed.]
I did a cold boot and the same thing happened -- eventually the
startup-sequence would start, but on the warm reboot I'd again be stuck
in that endless loop on the hard drive. Tried "Boot with no
startup-sequence" but got stuck in that loop again. Thinking maybe the
hard drive was just trying to validate itself after I tried
partitioning it a while back, I just let it run for a few
hours....nothin'.
Anyway...I disconnected the SCSI drive and modified my startup-sequence
[commented out both Oxypatcher and SetPatch so it wouldn't try to
re-boot]. Reconnected the SCSI hard drive, computer booted like normal.
Tried running HDToolBox but immediately got a guru. Rebooted, tried
HDInstTools, which loaded up and recognized all my SCSI devices. Tried
partitioning the drive -- only set up a 10-meg partition on FFS as a
test, as someone here suggested I do. I went to save and got "Error No.
1001." Tried the "format" option and got "Error No. 29." Basically, I
couldn't do a dang thing...
Soooooooooooo...while I'm still nowhere, I'm at least further than I
ever was before...
Clues??? :)
