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

Improper termination confusing the SCSI chain?

[Oldsmobile_Mike]

Not at present. My external CD-R/W is not connected, and an examination of the SCSI chain just shows 0 for the HD and 6 for the internal CD-ROM

I think you're misunderstanding the concept of "SCSI termination".  Check all of your jumpers.  In general, the last device on your chain should be the one with the jumper.  I.e., if a jumper currently is installed on your optical drive and you're adding an additional device on the chain, then you'll need to move that jumper to the (new) last device.

[Oldsmobile_Mike]

Yes, I knew that. I was just adding it to illustrate that I had no SCSI conflict.

You keep giving us the ID #'s, but you haven't said anything about if you've checked the device termination.  We're trying to help, really we are, but you're not giving us much to go on! :confused:

[Oldsmobile_Mike]

What else should I do?

Check. Your. Termination.

The way I have it connected right now is the way I've always (successfully) connected it in the past

If this is the case, and nothing else in your system has changed, you might try a different cable?

When is the last time it worked successfully for you?

[Oldsmobile_Mike]

Careful!! the 4000 desktop does NOT have a built -in scsi port!

Lol.  I wonder if he's connected it to his parallel port by mistake?

[Oldsmobile_Mike]

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:

[Oldsmobile_Mike]

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.

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

[Oldsmobile_Mike]

well, I clicked on HDToolbox (not CybSCSI Toolbox) and it appears the 2nd internal SCSI HD

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:

[Oldsmobile_Mike]

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

With HDToolbox

[Oldsmobile_Mike]

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

But is the drive physically connected to the SCSI chain? You mentioned it showed up, earlier. Regardless of if it's been partitioned and formatted it still need an appropriate ID and termination (or not, depending on where in the chain it's connected).
