Re: VFAT: Very stupid question
Hi -
Using debian x86_64 2.6.8-9-amd64-k8, I think I see the same problem
that greg reported in
http://lists.debian.org/debian-amd64/2004/10/msg00315.html
It gets stranger, though:
1. The same memory stick reads and writes fine on my x86 sarge
laptop.
2. When I check to see if VFAT works, using the method
described by Harald Dunkel in that thread, it does work.
3. fdisk /dev/sdb works fine, I see a 128Meg partition as sdb1
4. I get one more message out of the failed mount command
when I run it on the console:
FAT: invalid media value (0xb9)
5. After upgrading to 2.6.9-9-amd64-k8, I can no longer access
the partition table on the memory stick. /var/log/messages
cut-and paste appended.
Test conditions:
Kingston DataTraveler 2.0 Rev: 4.10
MSI K8T Neo2, MS-6702E
AMD Athlon64 3500+
This motherboard has four USB controllers, each one shows up as
VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller
This uses the memory stick with its out-of-the-box partition table.
Don't tell me to put a new partition table on it, that approach would
leave me in the dark when someone gives me their memory stick with
useful files on it.
I haven't recompiled a custom kernel for this box yet, but I will if
someone suggests a useful experiment.

P.S. I really like debian-amd64 on this computer. For an unstable
distribution, it's really very clean. This is one of only a handful
of warts. And the performance is phenomenal!
