IODATA IDSC21E SCSI bridge - this device is not supported by HDToolbox

I'm trying to use a recently acquired IODATA IDSC21E SCSI to IDE bridge to connect my CF card to my Taifun accelerator.... but I'm not getting anywhere with it.

I've tried with both the CF adaptor and an IDE disk, but neither of them will boot. If I instead boot from the CF disk via the motherboard IDE port and add the IDE disk on the IDSC21E, then when I load up HDToolbox I can see an IODATA device hanging off the ematscsi.device chain... unfortunately clicking on it gets the error: "This type of device is not supported by HDToolbox". So there's no way of knowing if the disk is actually there or not.

Has anyone successfully used these IODATA bridges to attach non-optical devices? I'm beginning to think I should have hung on for an Acard AEC-7720 instead.

what os? and which version of HDToolbox are you using bud?

I believe the first rule is don't use HDToolbox, use HDInstTools.

You should be able to get HDInstTools from Aminet, although I'm struggling to find it right now. I can always send you an LhA if needs be.

It's OS3.9 with BB1 and 2. KS 3.1 roms.

The main issue is that my CF card won't boot - the IDE disk was really just a test to see if the thing was actually picking up anything that is attached... which it doesn't appear to.

indeed Andy is correct, the version of HDToolbox makes a big difference, try updating it or take up Andy's kind offer of the LHA file he has :)

OS3.9 has the newer HDTools preperation software, so there should not be a need to change that.

I suspect the fault your having is in the SCSI termination and or Bridge setup.

can you post a pic of the bridge setup I have a setup chart thingy here.

If it's the PDF document, then that's what I used - jumpers 5 (SCSI-2) and 9 (enable termination) are set. No SCSI ID jumpers are set (ID 0). Jumper 8 is also currently set (though it made no difference to being open).

I've also tried with the termination between the two SCSI chains on the accelerator active and inactive (other than a global enable/disable accelerator setting, that's the only jumper on the Taifun). No difference.

There are no other devices on the chain (at the moment).

I've added an image of how the device appears in HDToolbox.

@ Megatron-UK

Both the controller and the hard drive will need a SCSI ID set. I would change the SCSI ID on the bridge and see if if makes a difference, as device 0 could be being used by the controller itself. All SCSI devices need an ID, including the controller.

Also, what are Termination and Termination Power options set to on the Taifun? Both ends of a SCSI chain need to be terminated, so they should both be set to on.

I've attached a SCSI CD to the chain as device ID 1, changed the IODATA bridge to device 2 and I still don't get anything useful from it - although the termination must be working ok as I can access the CDROM device.

Has the ide harddrive been set to master and not cable select before connecting it to the bridge? Just throwing that out there.
