Getting Commodore "insert WB disk" animation after attachng Jaz drive

[garyg]

Yes, I use it almost daily

[garyg]

The Amiga boots fine with nothing attached, so it can't be the HD (yet).
Where is the Phase5 program you describe? I don't recall seeing it on my HD.

[garyg]

By "nothing" you mean nothing external, right? The Amiga cannot boot well without the HD attached :-)

Right, nothing external

There are several SCSI options which can be set in the HD's Rigid Disk Block, like Synchronous, Reselection and so on. Some of them influence the whole SCSI chain. If one of the other drives does not work with one of these options, it might be the reason for the failure.

Didn't see this before. Is that second internal HD on the P5 SCSI bus, too?

I'm pretty sure it is (I didn't install it).

Are you sure that the boot HD has a different SCSI ID than the JAZ drive? Have you checked it?

Yes, 0 and 4, respectively.

Are you sure that the internal SCSI config hasn't changed since you used the JAZ drive last time?

Pretty sure. I'd been prettty careful about altering it. If I knew how.

IIRC the P5 SCSI kit has the internal devices on one end and the external ones on the other end with the controller in the middle, forming one long SCSI chain. If the termination of the internal devices changed, it might be a reason why adding an external device causes the whole chain to fail.

Well, as I said, the system boots with a CD-R/W drive connected externally to the Phase5 SCSI-2 port.

[garyg]

There is normally NO external device connected, and no other external device connected when the Jaz drive is connected. There IS an internal CD-ROM drive (SCSI ID 6).

[garyg]

By default, NOTHING is connected externally.

SCSI numbering:
HD 0
internal CD-ROM 6
external CD-R/W (when connected) 2
external Jaz drive (when connected) 4

I also have an external ZIP drive, whose SCSI ID is 5.

[garyg]

well, I clicked on HDToolbox (not CybSCSI Toolbox) and it appears the 2nd internal SCSI HD was added without an "update" in HDToolbox, so I chose Update.

Now I need to know just how to change the boot priority because the options that HDToolbox gives me are something like add a new drive or to partition, both of which destroy data.

I get the impression from the Harddisk manual that I have to choose Partition to get to the Change Boot Priority screen. Is that right? If so, I want to avoid destroying data at all costs.

Is it as simply as choosing Partition, then going to a Change Boot Priority screen, not getting in danger of erasing something?

[garyg]

Well, since I just updated the HDs via HDToolbox I don't know the ID of the 2nd internal HD. It shows up in the Early Startup menu, though.

I only add one external device at a time and make sure it's terminated (though I'd forgotten how the Jaz drive was terminated with a switch until recently)

Any idea on how to change the boot HD partition's boot
priority?

[garyg]

I don't think so. I didn't install the 2nd HD, and there's nothing else in the A4000 except Zorro cards

[garyg]

Yes, but with Partition or the other option?

[garyg]

Yes, it shows up on the Early Startup screen. I'm about to check

BTW, I have not only HDToolbox, but also CybSCSIHDToolbox, and SCSIToolbox on my Workbench.

[garyg]

Well, I went into HDToolBox, changed the boot prioritiy from 3 to 1, saved, and exited. Then I rebooted with the Jaz drive connected and turned on (and the light at the back was lit, indicating termination).

Nope, I still got the Commodore "insert WB disk" animation.

Early Startup did not show the boot drive (HD0:), although it did show all three partitions of the second drive (all non-bootable).

SysInfo soon froze while trying to find the SCSI ID of the 2nd drive. I wonder if perhaps it isn't connected to the IDE drive, since I vaguely recall now that the original 120MB IDE drive was removed when the 2nd drive was installed, so it wouldn't be a SCSI drive after all.

[garyg]

Just FYI y'all: I attached my SCSI ZIP drive, checked the SCSI ID (5) and termination, and everything booted up fine, and the ZIP drive works perfectly.

[garyg]

I'll try and check that theory by attaching it to another Amiga

[garyg]

You were right about that! I got a different Jaz drive with the same settings (SCSI ID, termination, SCSi connection) and it booted and worked fine!
