I did mention that I tried that as well. (but I just re-tried it anyway)
and it didn't have any changes.

Out of curiousity, I just tried to copy a file using an xterm (instead
of using nautilus) from DIsk 2 to disk1

disk2/partition2 - VFAT
disk1/partition6 - XFS partition (/home)


$ ls -lah WinXP-000001-cl1-000001-cl1-000001-s002.vmdk           
-rwxrwxrwx  1 root root 620M Aug 29 19:10
WinXP-000001-cl1-000001-cl1-000001-s002.vmdk

$ time cp WinXP-000001-cl1-000001-cl1-000001-s001.vmdk ~/Desktop/
real    0m37.353s
user    0m0.157s
sys     0m5.445s


Transfer rate ~16.8MB/s

Using Nautilus (I don't know of a good way to measure throughput using
this, so it's basically what I see in the progress bar
~5min
gkrellm2 notes transfer rate ~2.0MB/s


However, doing the same thing to my /tmp directory (ext3 partition) the
same file copies in ~30secs and w/ ~17MB/s transfer rate.

What gives??


BTW, what's the difference between mc and mc-mp??
