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

[garyg]

I've connected the SCSI cable to both connectors on the back of the Jaz drive. What else should I do? The way I have it connected right now is the way I've always (successfully) connected it in the past

I'm thinking of using a SCSI-2 to SCSi-1 cable and connecting the Jaz drive to the built-in SCSI-1 port on the back of the Amiga 4000.

Check. Your. Termination.

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?

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?

The OP has a Phase 5 Scsi board.

I located the manual today and noted the termination positions
and set the termination correctly, resulting in the termination light going on!

However, even though the A4000 %&$#?@!%&$#?@!%&$#?@!8220;boots%&$#?@!%&$#?@!%&$#?@!8221; the Commodore %&$#?@!%&$#?@!%&$#?@!8220;insert WB disk%&$#?@!%&$#?@!%&$#?@!8221; appears again!

You said it worked before...

WHAT did you change?

I changed the termination to ON (there are three options: ON, OFF, and AUTOMATIC, which turns the termination on or off depending on the rest of the SCSI chain)

I also set it to AUTOMATIC and got the same result, the "insert disk" animation.

No, what else did you change before this term thing. (you said it was working before?)
Was it always external, always connected, only connected for back up?

If always external, do you power on the ext box first, then the computer?

I haven't used it for a long, long time, but the configuration was the same. It's a stand-alone (i.e. external), SCSI device. I think the power switch was always set to ON, so I never thought much about turning it on or off before now.

I didn't change anything else, so it really puzzles me to get the Commodore WB 3.1 animation, as if it can't find a HD (and invoking the Early Startup screen displays df0:, and the three partitions of a second internal HD, none of which are bootable).

[SACC-guy]

Okay, It might be that the system drive is slower then the jaz. Is the jaz drive set up as a bootable disk? Does the ext box have a termination block on the outside?
It might be double termed now?

But the conflict is with the system drive being read first.
Try removing the cartridge, then first power up the ext box, power up the amiga, after it's booted, insert the cartridge, let it spin up and...hopefully be accessible...

[garyg]

Thanks for the insight! Most of the time I haven't had a cartridge in the Jaz drive, and doesn't have a termination block on the outside.

OK, I'l disconnect the Jaz drive, go into the Early Startup window and make sure the HD boo priority is set to zero (that's the lowest, right?)

No...
from amiga hard drive book, page 4-11
"It is suggested that you set your boot partition's priority to 1 and any other bootable partition to a priority of 0."

BTW, df0: has the default setting of 5.

[garyg]

I can't find my Amiga Hard Drive book. I went into the Early Startup Screen and saw that the boot HD was indeed 3 (and df0: 5). However, when I clicked on the entry it just toggled between bootable and non-bootable. How do I change the boot priority?

[Thomas]

Boot priorities only matter if there is more than one bootable device. The disk animation indicates that there is not even one bootable device.

I still suppose it is a hardware problem. Connecting the JAZ disables the HDD.

Does the JAZ drive have a power supply? If not, maybe there is not enough power for all the JAZ, the HDD and the Amiga from just the Amiga's power supply.

[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?
