  Stupid question (I am not a SCSI expert): Is this a wide harddisk?

  Sorry, same as before I am not an expert here. However, it seems strange
  that both programs refuse to work. Maybe they have a hardcoded unit
  check.

  I guess using "scsiconfig" was the mistake. Which program did you use
  initially to partition the disk?

  This seems to indicate that you used a different tool to setup the disk
  in the first place...

  Can't you use HDToolBox to restore the RDB? I guess using the FORCE
  option of rdbread won't do any harm. You will only loose your new
  scratch partition. Hopefully, you haven't written anything to disk
  after you played with "scsiconfig".

  You do only need this if you want to use FFS on a partition beyound or
  crossing the 4GB limit.

  The problem is that SCSIConfig has a different opinion than other tools
  used to partition a disk. I think if you create partitions with SCSIConfig
  and then format these with the AmigaOS format command, everything will
  work under AmigaOS. You will quite likely still have problems with NetBSD.
  However, I always thought that the warnings from the NetBSD amigaos FFS
  code are harmless...

  Thats not necessary.
