Anyone use thsfs to mount DOUBLSPACE CVF's?

I tried using it today, and am curious if anyone had better success.  I
was able to mount the CVF.  I proceeded to do an ls, and it took a long
time, but it worked.  I switched into the WINDOWS directory, did an ls,
and top showed that 'ls' was taking about 99% of the CPU!  It didn't
appear to do anything, but I made myself a cup of coffee, came back, and
it had actually listed the directory.

Then I did a "cd ..", did an ls, and it listed the same WINDOWS directory
again, despite the fact that the present working directory in my prompt
showed that I was not in the WINDOWS directory.

At work I tried mounting a DOUBLSPACE partition that was actually using
DOS 6.2 (as opposed to 6.0 on my home one) and it seg faulted.

I realize this is just in testing phase, but has anyone got any decent,
useful behavior out of thsfs?  Seems like a very useful module, if only
it worked a little better.

I had a lot of problems with thsfs as well. I got it to work on my Dos
6.2 doublespace drive after lots of work and kernel recompiling and such
and it is slow as hell.... I would almost call it unuseable. It's great
if you want to copy a little text document from DOS into unix but as soon
as you start dealing with any real quantities of data you can forget it.
I was going to copy my zipped up 4MB doom wad to my Linux partition and
at the rate it was going it would have taken well over an hour and a half
for four megs. I suspect the decompression algorithms thomas used in
thsfs are slow and very processor intensive. Theoretically it should be
possible to make a much quicker double space file system for Linux but
it's a matter of using the right algorithms I believe.

1. THSFS anyone?

: Dear All,

:       I've fetched Thomas Scheuermann thsfs package that allows to
: mount DoubleSpaced fs. It easily compiled on 1.3.59 but I didn't test
: it yet 'cos I'm still deciding whether or not to DoubleSpace my DOS
: partition. Is anyone using it? Does it works...? ;) What about
: EVENTUAL write capabilities?

:       Thanks in advance for any clues...

: PS: The author is no longer reachable at ai-lab.fh-furtwangen.de

I have actually used it some time ago. It did work but very slow.
I guess the original author does not maintain the package any more
because it is still the same then over a year ago.

I use DOSEMU to access my DoubleSpaced DOS partition.

Bye
