preserve all upper case filenames on vfat?

[jccheng]

Is it possible to preserve all upper filenames on a vfat mount? For example, if I want to name a file "FOO", it gets changed to "foo". Is there a mount option that would allow me to do this? My fstab entry looks like this:
/dev/hdc5 /mnt/win_d vfat defaults,umask=0 0 0 0 0
Any advice would be greatly appreciated.

Right from the mount man page:

check=value
Three different levels of pickyness can be chosen:

r[elaxed]
Upper and lower case are accepted and equivalent, long
name parts are truncated (e.g. verylongname.foobar
becomes verylong.foo), leading and embedded spaces are
accepted in each name part (name and extension).

n[ormal]
Like "relaxed", but many special characters (*, ?, <,
spaces, etc.) are rejected. This is the default.

s[trict]
Like "normal", but names may not contain long parts and
special characters that are sometimes used on Linux, but
are not accepted by MS-DOS are rejected. (+, =, spaces,
etc.)

and

shortname=[lower|win95|winnt|mixed]

Defines the behaviour for creation and display of filenames
which fit into 8.3 characters. If a long name for a file exists,
it will always be preferred display. There are four modes:

lower Force the short name to lower case upon display; store a
long name when the short name is not all upper case.

win95 Force the short name to upper case upon display; store a
long name when the short name is not all upper case.

winnt Display the shortname as is; store a long name when the
short name is not all lower case or all upper case.

mixed Display the short name as is; store a long name when the
short name is not all upper case.

The default is "lower".

Thanks for the tip! Worked like a charm.
