[USB disks] FAT: invalid media value (0x01)

[USB disks] FAT: invalid media value (0x01)

[Paweł Sikora]

Hi,

I have two usb devices: photo camera (nikkon d70s)
and mobile phone (motorola e398). Both have worked perfect with 2.6.14.7.
With recent 2.6.16.18 none of them work, e.g.:

I've checked the FAT table and everything looks fine.

Any ideas?

It would help if you narrowed it down a little bit.

Ohhh, It was a typo in my /etc/fstab.
s:/dev/sdc:/dev/sdc1: and everything works fine.
Thanks :)

Well, it depends what "it" is...

                                                ^^^

Shouldn't it be looking on sdc1 for the filesystem?

This could be some kind of hal/udev screwup.
