Hi moto,

I thought the unitcontrol program automatically mounted the scsi drive for you, rather than having to manually edit a mountfile?  It's been a while...
IIRC aren't there some configuration variables at the bottom of the mountlist, telling it to use diskchange interrupt, scsidirect, etc - perhaps these may need changing from the previous settings?
Either that, or you could re-install IDEfix97 and get it to mount your 1230scsi.device during the scannow section.  

The termination on the Blizzard scsi controller is hard-wired (a set of resistors soldered to the board).  These look like, erm.. skinny little caterpillars?  It's be fairly obvious if they'd been removed, as there would be a couple of lines of empty holes around here.

Hi moto,

Have you tried increasing the number of buffers (eg to 150) in teh CDFS prefs on that drive?

If you've got the original IDEfix97 program somewhere I'd seriously consider reinstalling it and allowing the program to pick up the drives when scanning the 1230scsi.device during installation.
I seem to remember having a similar problem on IDE - turned out I'd installed the CDrom as a scsi device rather than an atapi device.  Don't suppose that's much help here though.

Hi moto, don't worry, I've not gone IDE-SCSI loony :crazy: I suggested IDEfix as it seems to scan all devices on all buses, and seems to do a good job of mounting them OK (imho) - including PCMCIA and scsi.

Looking at your mountlist though, there seems to be no entry for STACK=xxxx .  THIS could account for your errors on larger files.  If Amigakit was using stackattack in his startup-sequence it wouldn't hav required it in the mountlist (AFAIK) but if you don't have stackattack in your startup this would make a difference.

I suggest you try putting a line in for "stacksize      =3000" (3000 is the recommended minimum) - on my CD mountfile it is after the "dostype     =" line.
