Hack 41 Determine Your Filesystem 
How do you tell what type of filesystem your
disk is partitioned with?
In
Windows, open My Computer,
right-click on your hard drive icon, and then select Properties.
You'll see a dialog similar to that shown in Figure 5-2. Within this dialog will be a designation of
the hard drive's filesystem, in this case NTFS. With
NTFS under Windows NT, 2000, or XP, we are assured of significantly
more efficient use of available drive space than with FAT-16 or
FAT-32 under DOS, Windows 3.x, 9x, or Me.

The
mount command under Linux will also
show you filesystem types, as in the example below, which shows an
ext3 filesystem type:
[root@rh9-lt root]# mount
/dev/hda2 on / type ext3 (rw)
/dev/hda1 on /boot type ext3 (rw)
