i'm new to linux in general and especially to Slitaz.
i've booted to ophcrack slitaz and my usb ( FAT32, 2GB )
is also is in read only mode.
i'm logged on as root.
tried to change the usb fs to FAT and NTFS.
when formatted as NTFS it's not listed in the PCmanFM
when formatted to FAT , same issue as with FAT32.

without mounting it i can see it's already mounted after boot in the PCmanFM.
when i try to unmount it , the following error is given :
"Error org.freedesktop.Hal.Device.Volume.UnknownFailure"
in the PCmanFM console the usb appears to be in /mnt/sdb1

in the mountBox i can see a mounted fs :
/dev/root 1.8GB ...
in the Umounted dev section nothing appears.

when i ran the "dmesg" command as suggested else where,
i got a lot of things but at the end of the output it says :
..
..
usb-storage : device found at 2
..
sdb: sdb1
sd 2:0:0:0: [sdb] Attached SCSI removable disk
sd 2:0:0:0: Attached SCSI generic sg2 type 0

also tried to run :
"mount /dev/sdb1 /media/usbdis"
mount : mounting /dev/sdb1 /media/usbdisk failed: Device or resource busy.

in other forums people suggested to check for information in /etc/fstab
proc /proc proc deafults 0 0
sysfs /sys sysfs deafults 0 0
tmpfs /dev/shm devpts deafults 0 0
#/dev/hfa3 /home ext3 deafults 0 2
#/dev/hdb1 /mnt/data ext3 deafults 0 2
/dev/cdrom /media/cdrom iso9660 user,ro,noauto 0 0

i would really appreciate any help.
thanks,
