I am copying files from an e3fs to VFAT. Both should have filename case, as far as I can see. The VFAT FS is currently mounted as:
mount -t vfat -o utf8 /dev/disk/by-label/Elements /mnt/tmp
however, I think that it is immaterial, I have tried several combinations, to no avail.

The source has rather mixed cases:

sorry for the formatting, I hope you can read it. You have a capital F, then a sequence number, then the extension, which may be TIF or tif.

Now I see that, if the extension is TIF, the initial F, as well as the extension become lower case:

root@linuxserver:/mnt/tmp/backup/museum/foto-collectie/F-09000-F-10000# ls -l f-0999*
-rwxr-xr-x 1 root root 20224000 2008-04-06 15:04 f-09990.tif
-rwxr-xr-x 1 root root 11627574 2008-04-06 15:04 f-09991.tif
-rwxr-xr-x 1 root root 20573132 2008-04-06 15:04 f-09992.tif
-rwxr-xr-x 1 root root 14203458 2005-10-07 11:59 f-09993.tif
-rwxr-xr-x 1 root root 20216940 2008-04-06 15:05 f-09994.tif
-rwxr-xr-x 1 root root 19641726 2008-04-06 15:05 f-09996.tif
-rwxr-xr-x 1 root root 12977074 2008-04-06 15:05 f-09999.tif

and if it is tif, then the F remains upper case.

root@linuxserver:/mnt/tmp/backup/museum/foto-collectie/F-09000-F-10000# ls -l F-0999*
-rwxr-xr-x 1 root root 21504168 2008-04-06 15:05 F-09995.tif
-rwxr-xr-x 1 root root 21269692 2008-04-06 15:05 F-09997.tif
-rwxr-xr-x 1 root root 12744736 2008-04-06 15:05 F-09998.tif

Somehow this makes no sense to me. Is there any way to do anything about it?

Odd indeed.

Don't know what's causing the weirdness, but try adding 'case=asis' to the mount options and see if things get a little more sane.

Unfortunately mount won't accept case=asis for VFAT.
