I stand corrected. I have the Z8603 and format ROM/jumper for a 5MB Profile and a Z8613 plus format ROM/jumper for the 10MB Profile but haven't had to format my 10MB Profile. In my case three 5MB Profile drives wouldn't complete the low-level format properly with BLU. BLU did low-level format a Widget drive but it doesn't need any special chips or ROMs.
Celgen, it sounds like you need a low-level format.
I have been thinking of using the earlier version of BLU to see if that makes a difference. One of my drives was a IBM compatible Seagate ST-506 drive that I switched the boards on and this is one of the three drives I couldn't format. Unfortunately, I don't have a PC that has the proper MFM card with BIOS that will allow me to low-level format in DOS to see if the drives would work on a PC.
I'm losing hope on them but the failure in BLU is consistent. Unfortunately, I don't have a Apple /// Profile card in my Apple /// and special software to try that route.
