Can't write on my usb pen drive from 2 days?!?

hi, from 2 days i can't write on my usb pen drive (Transcend JetFlash Flash  16gb with FAT32 partition)

if I do a manual mount in a console by root, I can easly a do cp command and copy files over.

if I open dolphin and mount by hal the drive,  I can read but not copy files, and if I open a console and do a cp command, I have this error:

cp: cannot create regular file `/media/OZETA/ownage.png': Read-only file system

what the... is going on? i used my pen 4 or 5 days ago

on the contrary, i can mount my sd card (fat32) and my 2 usb disk (fat32 and ntfs) and i can write on them.

help

What does your /etc/mtab say when you have mounted your usb pen drive? Maybe it's ro not rw <shrugs>

/dev/sdb1 /media/OZETA vfat rw,nosuid,nodev,uhelper=hal,uid=1000,utf8,shortname=mixed 0 0

I'm sorry, but I don't know what dolphin is, what it does and how it works - I don't even have HAL :-) I mount from the console so I don't have such problems, but unfortunately that also means I'm unable to help you. Good luck.

Have you tried running dosfsck on the device? Of course, be sure that you unmount the usb drive and verify the dev file of the relevant partition.

Something like:

dosfsck /dev/sdb1 <----replace with correct dev file!!

to see what the problem is and then

dosfsck -a /dev/sdb1

Of course, I would strongly encourage you to backup all data on the drive first.

@ozeta
Could we do a little test? Create a new partition from Arch and please set your fstab to

/dev/sdb1 /media/OZETA vfat user,rw,umask=111,dmask=000 0 0

(edit device name and mount point accordingly).
Please write if you can write to it as a user.
