I ran into this problem about a month ago, but am a little fuzzy remembering
the details. Seems as though I saw the problem after TML Pascal would abort
on me. (I don't know why, but TML Pascal [APW version] usually aborts the
second time I try to compile!) After I got that error, I copied the files
to another disk with no problem...until the compiler aborted again.

I believe the problem occurs when the directory entry does not match the
"sectors in use" bitmap. When I took a directory listing (via APW) on the
"bad" disk, the total of used and unused blocks did not match what I
expected.

Perhaps your directory also is somehow damaged. Try copying the files one
at a time, then seeing if the number of blocks totals up correctly.
