SubjectProblem with 'mount -t vfat' on PPC
Hi,

I have a problem, when mounting a DOS-File-System with "mount -t vfat":
Most (long) file/folder names are corrupted.

I actually mount a Compact Flash card via an USB card-reader.
My secondary device, an "Ericsson MC218", is equivalent to a "Psion MX5".
This PalmTop computer uses EPOC as os and I try to exchange files
via Compact Flash card (to get Linux running on the MC218...).

On the Linux-side every character in a name is replaced by a "?" (question-
mark), on the MC218 alle names appear empty.

I can exchange data CONTENT with no problems. I tried to USE files
transfered from Linux to the MC218. This worked fine.

When I use "mtools (1)" all works fine!

As I mailed with the maintainer of the card-driver he thinks, that the
driver is OK. He thinks, that mtools uses its own FAT-handling
and the problem is in the kernel...

I had sometimes problems with byte-ordering (big endianess) before when
I used relatively new modules...

My configuration:

Hardware: Apple PowerBook G3 (bronze keyboard)
System: SuSE Linux 7.1
Kernel: Self compiled kernel 2.4.12

Reader: DataFab DSCFSM-USB
Dual Storage
Compact Flash
Smart Media
USB

Card: /dev/sda1
FileSystem: FAT16, Linux

I would prefer to mount the CF-card as Linux file-system...
