Hello folks,

After mounting a fat32 partition, the directory listing shows
everything in capital letters. This is very annoying. Does anyone know
how to solve this?

Thanks,
Mark

I believe there is more than one way to mount an FAT-32 partition. Could
you please give us some sample output with which to work? Have you tried
using both the msdos FS and the vfat one?

I tried mount /dev/wd0i /mnt/data, mount -t msdos /dev/wd0i /mnt/data,
and mount_msdos /dev/wd0i /mnt/data. I think they all boil down to the
same thing.

I tried mount /dev/wd0i /mnt/data, mount -t msdos /dev/wd0i /mnt/data,
and mount_msdos /dev/wd0i /mnt/data. I think they all boil down to the
same thing.

Look in the man page for "mount"

There is an option "-o" for passing options to the actual
filesystem-specific mount program.

Then look at the man page for "mount_pcfs", and you will find
the following:

================================================== ====================
foldcase|nofoldcase

Force uppercase characters in filenames to lowercase
when reading them from the filesystem. This is for
compatibility with the previous behavior of pcfs.
The default is nofoldcase.
================================================== ====================

Note that this means that *all* characters will be lower case.
The FAT format directories don't handle mixed case filenames, or
anything other than the 8.3 format. (And all filenames are all upper
case, which is why you are seeing what you are.)

There are other tricks which will read some metadata saved
invisibly on the filesystem to display in mixed case and with more than
one '.' among other things. I'm not sure that FAT-32 supports this,
however, the best you can be sure of doing is using the "foldcase"
option to render it in lower case.

However, I don't know how to specify this for a FAT filesystem
mounted on a Sun. (I think that the same trick is used in some other
things, like the hsfs (the standard filesystem on a CD-ROM), but I don't
know how to get this to apply to a FAT filesystem.

Good Luck,
DoN.

Thanks for your elaborate reply. The problem is that I don't want all
characters to be lowercase, but just the ones that really are
lowercase. Windows is showing me the directory listings correctly, and
that means OpenBSD should be capable of doing the same thing (at least
in theory). I noticed something else. If a filename contains a
combination of uppercase and lowercase characters or the extension is
not 3 characters long, it does show the filename correctly. Anyone?

FAT32 actually has two places it stores filenames. This was to
facilitate going beyond the 8.3 limitation. It sounds like in this case
it is deferring to the extended name under some circumstances.

This shouldn't matter, but did you try mount_msdos -l?

I tried, but it doesn't help.

Well, it shouldn't, but that was about my last idea. You might want to
retry on misc@openbsd.org. (If you already did, I'm sorry; I'm a bit
behind, and did not see any subject that looks like it would relate to
this query.)
