GSOS File copy error: System Error ($0040). Thoughts?

[Warren Ernst <wernst@gmail.com>]

All,

Just thought I would ask about this error I'm getting:

Under GS/OS 6.01, when copying multiple files in the Finder from one
partition of my CFFA to another, I usually get this error partially
through the copy process:

System Error ($0040). This operation can't be completed.
Invalid pathname syntax.

I can then copy the files one or two at a time  without troubles. The
partitions are named CFFA1 and CFFA4, and the foldernames and
filenames are perfectly legal.

I can copy whole groups of files with 8-bit software like Copy II Plus
without troubles. This happens with and without Dave Lyon's CFFA
driver installed. I have a ZipGSX 8/64k and I get the same error when
the accelerator is enabled or disabled. This GS is otherwise very very
reliable, as I am able to compress and decompress large shrinkit
archives without errors.

So, can anyone shed any light on this error, what it means, and how I
might solve it if possible?

Thanks,
Warr
