ipod (read only file system)

hi guys,
i am getting a problem with my ipod.

I have reformated my ipod in order to have an hfsplus without journaling file system. The ipod has been working fine since May 2009 (for 3 months) and i have al my music there, but now gtkpod reports problems when trying to transfer files to the ipod.

From root i have checked it and it suposse to be a RW file system:

Code:

mount

/dev/sdc2 on /media/iPod type hfsplus (rw,nosuid,nodev,uhelper=hal)

however, when i try to write into the ipod, it looks like a read-only filesystem:

Code:

chmod 777 /media/iPod/

chmod: changing permissions of `/media/iPod/': Read-only file system

i wonder how it happened?

any ideas ?

thanks in advance,

Hector

pd. i have fedora 10.

hi guys,

it looks like the Filesystem was not cleanly unmounted:
