scsifmt from scsitools should work to low level format the drive.
I bought some AS400 drives from ebay last spring. Wouldn't work until I low level formatted them. I did the format from the AIC controllers bios though. Never used scsifmt, but it should accomplish the same task.

or similar. There used to be a command for low level format of scsi discs. You don't need the controller's utilities.
Have fun :) Ionut

Hi, I have an UP2000 motherboard with an on-board AIC-7891 SCSI controller. I'd like to attach a disk which has a block size different from 512 bytes. Is it posible to start the controller's scsi utilities before or from the SRM console to modify the block size? cheers dino

I can't really use scsitools bacause the drive has an unusual block size. The kernel gives the following message durng bootup:

and I can't reach the second disk with scsitools (there's no sdb device). I was told that a low level scsi format with the controller' disk utilities can modify the block size.
so the question remains: how could I start the controller's utilities before bootup?
