Hi,
I just bought an usb-stick/mp3-player (Medion pro2 (MD40838), 256MB).
This is (summarized, I put a lot of detailed info below) what happens when I
try to use it with my SuSE8.1 box:
When I plug it into my hub, it's obviously recognized as a mass-storage device
and I can mount it using the following fstab-entry
/dev/sda /media/mp3player auto rw,noauto,user,sync 0 0
or directly (as root) with:
mount -t vfat /dev/sda /media/mp3player
Doing so will let me copy mp3-files to the stick and after cleanly unmounting
and removing it I can listen to the files on the player. Fine.
Now comes the strange part (besides the mount-command above, which I don't
understand, because I should mount one of the four partitions and not the
whole disc, right?):
When I plug the stick into the hub again, wait for the affirmative beep from
my box and then unplug it, all the files are gone (the player shows "no
files" on it's display). This happens _without_ mounting it, just plug in &
plug out! If I mount it, it'll be empty, too - of course.
If I recorded sth. using the built-in voice-recorder or put sth. on the stick
using a windoze box, it'll stay on the stick. Meaning those are the only
files I ever get to see (using linux) on the stick after mounting it, all
files added by the linux box vanish.
I have no clue what's happenin' here or what I could do about it. I added all
the details I could think of below, if you need any more information to point
me in the right direction, I will happily provide it.
And yes, I read the thread "Packard Bell Audio Key w/ Linux *and* W98". I
think his hardware is the predecessor of mine, but mine won't even work using
"only" linux (see above).
At the end of the thread he is advised to reformat the stick with more than
one partition. I thought about reformating mine with one (or more) partitions
because of the strange messages "fdisk -l" gives me (see below), but I'm not
sure if I can just do that using fdisk. Is that save? Could I wreck the
player?
thanx for any hints on how to continue,
Johannes
PS: My system is a standard SuSE8.1, standard meaning: as it installs
automatically without tweaks.
