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

[polyp2000]

I'm trying to back up my HD to a 2GB Jaz disk, but after attaching it to the SCSI-2 port of my A4000's Phase 5 SCSI-2 port I get the Commodore "insert WB disk" animation, yet the computer starts up normally if the Jaz drive is disconnected.

Anyone have any idea what's wrong and how to fix it? The Jaz drive's SCSI ID is 4, the internal CD-ROM's ID is 6, and the HD is of course 0. That's all the SCSI devices.

Is backing up data to a format that hasnt been in production since 2002 actually a sensible idea?

Yes, the Jaz drive has its own power supply. The Amiga boots with an external CD-R/W attached (which has its own power supply). Its boot priority is unknown.

Unfortunately, the CD-R/W model seems not to be supported by the CD-R software. So it does seem to revolve around the boot priority

[garyg]

Yes, I use it almost daily

You should boot from floppy with both drives attached and use Phase5's UnitControl program to check whether the JAZ drive is recognised. The program can also rescan the SCSI bus. Until now you only said that the HDD is not recognised, there is no information about the JAZ drive yet. Maybe the YAZ drive is faulty and the whole SCSI chain is disabled because of some malfunction.

It might be dangerous but it might be a possible test to boot without the JAZ drive and connect it later (or have it connected but power it up later), then use UnitControl to get it recognised.

Could it be that it's not the JAZ drive, but the HDD? Maybe you changed some options on the HDD after you disconnected the JAZ drive last time "in the past".

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.

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

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.

"SCSI Systemdisk" on this page: http://phase5.a1k.org/

invoking the Early Startup screen displays df0:, and the three partitions of a second internal HD, none of which are bootable

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

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

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

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.

Right, nothing external

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

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

Okay, let me see if I got this..

Your 4000 has a Phase5 scsi controller..
which has a hard drive inside the 4000 case and an ext cd and an ext jaz drive. (2 boxes)

Do you have the cd attached first and then daisy chain to the jaz? Or the other way?
If so, make use the first ext device is NOT terminated! Only the last scsi device should be terminated.

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).

I still don't have a clear idea how many devices you have connected, lol.  :lol:

For simplicity sake, why don't you change the numbering so that the one furthest away is the highest one?  For example:

A4000 --> Internal Phase5 SCSI controller card --> Internal hard drive (set that as ID 1) --> Internal CD drive (set that as 2) --> External CD drive (set that as 3) --> External Jaz drive (set that as 4, stick a termination jumper on it, and remove the termination jumpers from all of the prior devices in the chain).

That's making a lot of assumptions, but you know, gotta start somewhere. :laughing:

[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?

As you're swapping those external devices around you're swapping the termination jumper, right?

[Oldsmobile_Mike]

You didn't include that in your previous list.  What ID is the 2nd internal SCSI HD?

Again I suggest you simplify a bit.  Start with one device (for example, your main hard drive).  Remove everything else for the meantime and make sure your system is working 100% correctly.  Then add a second device (for example, your second internal HD).  Make sure your ID, termination, partitioning, and everything else are 100% correct and that the system works well and is stable with these two devices.

Next add the third device (this would probably be that internal CD-ROM you mentioned).  Swap the termination jumper, triple-check that there's no ID conflict with the previous two devices, etc.  Make sure all works well in this configuration and then go on to the next device.

You get where I'm going at with this, right?

If I understand your posts correctly you have a total of six devices (two internal hard drives, one internal CD-ROM, one external CD-RW, one external JAZ drive, and one external ZIP drive).  That's quite a lot.  It'll be a lot easier if you start at the beginning and work your way up.  Or you can make it harder on yourself, your choice!  Lol. :lol:

[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?
