I asked the same question a year ago when I was writing HDSCAN. Had
the same problem, but since HDSCAN wasn't really intended to do much
heavy work FROM the floppy, I decided to hold of on the workarounds.
I tried LOTS of permutations with doing FSFIRST, etc. It would work
sometimes, but not reliably. I just got through writing a new program
that has to read the floppy subdirectories, but now I can't get the
problem to pop up at all. I am using MWC 2.xx (I originally had the
problem on MWC 1.x and OSS Pascal 1.xx both of which are dust now).
The file open calls I am currently using to open the files for access
are Fopen and fopen (don't ask...) and I do try to open a file at the
root level (either a direct file or the volume name...doesn't matter)
before any access to the sub-directories on the disk.

This is one of those problems that makes it so fun when I port my code
back and forth between the ST and Unix...

(Yes, Jim S...DISKSCAN is now done and you really will get the first
copy!  And the TOOL-WARE version will be in the Snail Mail to those
of you patient people who liked DISKTOP enough to send in $$. Note
that I am hesitant to use the 'S' ware word on the net after all the
strange arguments that pop up when people see it :-). Oh, BTW, DISKTOP
is shelved until OSS Pascal 3.00, or whatever version, fixes the
flakiness in 2.xx. I don't expect any future for DISKTOP with DISKSCAN
available, anyway...)
