Subject: mounting extern FREECOM HD in squeeze
To: debian-user <debian-user@lists.debian.org>


Dear All!

I am having problems getting a stable mount of an extern*FREECOM HD on debian squeeze.
Sometimes it mounts and by running*# blkid -o list -c /dev/null

get*
/dev/sdb1 *vfat * *FREECOM HDD /media/FREECOM HDD 13EC-4051
but it often umounts while copying files and can not mount it again. *Tried

placing the line in fstab
UUID=13EC-4051 */media/Ext-HD vfat defaults,auto,exec,users,rw 0 0
but get
mount: special device UUID=13EC-4051 does not exist


also*/dev/sdb1 is gone.
Any missing mod that I should look for?
Any ideas are welcome.
Thank you in advance,
Filipe
