I think you just might be right. This should not be, but different
controllers have different scatter-gather logic. It turns out that
logical sector X on one controller may be logical sector Y on another
controller. It's not the low-level format that's different. A new
file-system has to be built when installing a new controller.

We will see. I have a new Linux file-system and a new MS-DOS file-system
now... The other file system that is a "VMS/Clone" will have to wait. I
will have to rebuild it from zillions of floppies.

I think that a bad "seek", i.e., a read or write beyond the end of the
physical media, caused Linux to be trashed. Therefore, subsequent writes
were to __OTHER__ devices, not even "known" to Linux.

The driver maintainer really should look at the exception handling.



Cheers,
