I did that.

I used a Win XP machine as client / server.

Also did this.

It's the only drive it has, I meant the second machine is all new, not
just the disk.

The fsync() problem seems to be related to that, but the rest could be
be a different thing. Also I only got it twice. Maybe the filesystem
issues were only derived from the crashes.

I was unable to reproduce the problem in the first machine, maybe it
was fixed on FreeBSD 6.2 as you said. The only things I also did when
testing was unloading fuse.ko (unused) and linprocfs.ko (after
umounting it). However I will test it a few times more, and let you
know the results.

The strange crash in the new 6.2 machine when using atacontrol is still
unexplained and I couldn't make it happen again (it now refuses to
switch to UDMA100 mode when it is SATA300, maybe they aren't supported
in SATA drives, but the other time it just crashed without advise).

Thank you for your help with this.
