I know for a fact that there is a problem with partitioned USB disks and a certain kernel configuration. I had a simillar problem with my iPod.Hi List,
have been wrking on this for some days now...
i have an external (powered) usb disk (macpower icecube,200G), which i need to attach to my pismo running 2.6.11, Debian testing.
After connecting the drive to the computer, i see the partitions in /proc/partitions:
8 0 195360984 sda 8 1 32764536 sda1 8 2 32764567 sda2 8 3 32764567 sda3 8 4 97064730 sda4
The first three partitions are FAT ones.
but as i try to mount them:
mount /dev/sda1/ /mnt
i get:
/dev/sda1 is not a valid block device
and the partitions disappear from the /proc/partitions file, i have to power cycle the disk, and the whole thing starts again.
I had success mounting and using the disk on an x86 debian box.
I am able to mount my memory stick on the pismo.
Any help would be, oh so appreciated!
regards, Peter

Long story made short: I used the ubuntu config as a starting point to make my own kernel that can mount partitions.
More info is on www.linuxquestions.org at the end of a thread called "ipod mini - usb on a SuSE system". Google for : "recompile the kernel and make sure u do this" to find the thread ( I haven't checked if Google returns results, but the forum supports searching ). The last 3 posts explain how to make the stuff work. If you need a config i will send you mine.
