I am currently using an Amiga 500 system with one 3 1/2" drive internal
and a 5 1/4" drive external, which I generally use for IBM programs when
using my emmulator. With Amiga Dos 1.3, however I would like to be able
to set up my 5 1/4 to run under the FastFileSystem as an Amiga drive.
The drive is an Amiga one and I was able to use it for Amiga files under
1.2 with no problem.
NOW THE PROBLEM
---------------
When I mount it as a FFS device it formats fine, validates fine, but does not always store data. It messes up ASCII files saved to it and often makes object files unexecutable for apparently no reason. When I INFO the system it reports no disk errors or other problems, but diskdoctor reports that several files haveblocks used more than once. Since I could not safely write to my 5 1/4 under FFS I was unable to transfer data from my old 5 1/4 s to the new format so I
wrote my mountlist to make my external drive think it is both DF1: and DF2:
DF1: is FFS and DF2: is standard. This setup allows me to read my old disks by calling DF2: and to try to use FFS by calling DF1: as long as the proper disk is
in the drive when I do a Diskchange this works fine.
I would like to know if anyone knows why I am having problems with FFS and how
to fix them. Below is a copy of the mountlist I am using for DF1: and DF2:
(with both the same physical drive) incase it is a problem with the mount
entry.
Any help would be appreciated.
