Just as a sanity check...
Is the ifs=jfs.ifs line the *first* IFS in config.sys? It must be loaded
before any other filesystem, especially hpfs and fat32.

It is beginning to sound like the partitions have been marked hidden or
something added to each partition that makes the superblocks (FAT) not
readable. He needs to take the data files that the Dfsee author
requires to figure this out.

Yes, I spent many hours with DFSee yesterday and all that I could
see was that after a complete boot to the GUI then in DFSee
Display -> Volume overview
DFsee says
OS Vulume info : D: Not ready, no size info, fs: UNKNOWN
for all the JFS partitions and the FAT one.

If I boot to the command line from the boot blob, then they all
show correctly and are accessible.

It seems that something late in the boot process marks them
not ready, but what & why, I have no idea at the moment.
I presume that most of the dfsee tests display data from the
disk itself, but this volume overview test uses, possibly different,
OS API calls.

Another thing, I took the non-system disk out and put it into
another PC, no problems at all!

Confused,
