I found a pretty good Win32 ASPI specification at http://www.google.com/search?q=cache:www.rad.kumc.edu/share/dos /ADAPTEC/ADAPTEC/ASPI_W32.TXT+SC_HA_INQUIRY+maximum+target+coun t&hl=en It seems that at least part of the problem is the "maximum target" field, i.e. byte 3 in the HA_Unique array. I simply banged that up to 8 in SS_HA_INQUIRY, and now the Polaroid software at least takes a closer look at the SCSI stuff. In the end, it still comes back with the same error message, but as someone famous once said "we are now confused at a whole different level" ;-) I'll have a look at the traces now, and see whether I can work out what goes wrong now. Just wanted to get this information to you in case it will also help your problem. I'll keep you posted, Bernie
