SCSI, FFS & SFS

[Cass]

I`ve got a real serious problem recently:
My system was based on a standard A4000 IDE HD, but I wanted to try the CSPPC`s SCSI.

Before everything was all right, with a 2.1GB HD FFS & BSD partitioned, and another 1.1GB HD SFS. No problems so far.
After removing the 1.1GB IDE, and adding a 4GB SCSI (2 FFS partitions & 3 BSD partitions) there were no problems. I`ve tried to format one of the 2 FFS SCSI partitions as SFS. I even managed to copy some files in the new SFS partition.

And then after a reset the AMiGA wouldn`t boot. Some disk activity, black screen, and a reset. The early ss menu wouldn`t work.
I managed to get to the early ss menu by deactivating the SCSI controller. There must be something preventing the system from normal boot sequence.

Is there anyway to restore the scsi rdb, or reformat as ffs the SFS partition?

1) Deactivate the unit (set to zero LUns) in the CSPPC early boot menu
2) Boot as normal
3) Use the unitcontrol tool (or is it the scsiconfig tool - I always get the two mixed up) to activate the scsi unit previously deactivated in step 1.
4) Run HDtoolbox
5) Change the filesystem back to FFS and save changes.
6) Reboot, and use the early boot menu to reactivate the scsi unit with 1 lun.

Has worked for me in the past. :-)

Obviously, you will lose the data on the partition for which you are changing the filesystem.

Exact same problem here!
Thanks to your prompt response and instructions, I`m now copying the backup data to the reformated partition. The system is up and fine, just like before! Thanks Boot_WB, here`s a  :pint: to you :-D.

P.S. I`ve lost the P5 disks, so I found handy the SCSI Tools DMS images here.
The util needed is UnitControl (v2.17 worked fine for me). I pressed "Rescan", the drive appeared on the list, I selected it, and pressed "Start" (not "mount" because it crashed!). Next, HDToolbox, and removed the SFS partition, set it as FFS.
