Ive got two Jaz drives. The first is a 1GB internal and is installed in my 3000T. On the SCSI chain I have a SCSI2SD - v5.2; the JAZ and then a SCSI CD-ROM; on the external SCSI port I have a SCSI CD-RW. The CD-Rom and the CD-RW are both terminated. This drive is the less probematic of the two.

The 2nd JAZ is a 2GB external drive I couldnt it get to work with the 3000T. Took ages to boot. I did manage to install a 2GB disk using HDToolBox (OS3.9 version) with PFSAIO. Problem I had was after partionitiong and then formatting the disk showed as blank after a reboot.

To check the drive was ok I tried to use it with my 3000D. Seemed to work ok last night. I managed to copy my boot drive to a 2 GB disk and thought all ok. This morning the A3000D wouldnt boot at all. Disconncting the JAZ - booted ok. Reconnecting the JAZ without a disk - booted ok. Inserted a disk and no boot.

Thinking it was a problem with the SCSI chain I put the JAZ as the first device; 2nd device is a SCSI2SD; 3rd CD-RW and 4th Iomega 100MB ZIP. The ZIP drive is terminated. With this set-up it has been working but I get write errors. File system is PFS AIO V3.2 (beta).

I do wonder if Ive got bad 2GB disks. I got the drive with four used 2GB disk - possible they are bad disks.

Yep. Have had plenty of issues with PFSAIO with Jaz and Zips. I’m finding the version 20.0 BETA that Toni Willen has for download sorted that out. If using 19.2 then recommend making sure that you stick to the basic givens that HDToolbox comes up with. A lot of my issues are with booting on the Jaz and Zip. But if you stick to 512 max transfer with v 19.2 you are good. With BETA 20.0 you can go to 4096. Also dependent on SCSI and what tools you have. Play around with async and sync modes.

Thank you very much for your reply,
I thoroughly cleaned every sign of oxidation, removed it with a fiberglass pen and reapplied the solder-mask, as in the images below



I also did a recap of the power supply and now the voltages when the computer is on are 4.88v / 11.67v / -11.40v / -5.08v

I also noticed something. If I restart the Amiga 2000, when it's hot and has the graphical glitches, it doesn't load the Kickstart but goes directly into guru meditation, but if I insert a Buddha IDE, which has a small RAM expansion on board, it loads the kickstart, but still full of artifacts. So I'm starting to think that there's some ram module that doesn't work well or at least some track related to memory management. Unfortunately I don't have a DiagROM to be able to test.

What do you think?

Hi all,

Whats the difference between the various versions of HDToolbox? I'm running OS3.2.2.1 with KS 47.111. It takes ages 'checking scsi.device address 2 unit 0'. The device is a iomega JAZ 1GB drive. I have the same happen with a 2GB Jaz connected to the external SCSI on my A3000D, also running OS3.2.2.1.

If I run HDToolbox OS3.9 I dont have the same issue. Its asks to select the scsi.device then opens up without issue.

Whats the difference between the versions?
