after reboot system my mounted external hdd will be internal device

Thanks for your bug report, however I am not really clear on what the bug is that you are reporting. Could you give us more information about how the USB hard disk becomes internal? Could you also add /etc/fstab before and after your changes to the bug report? Thanks in advance.

i'll trying :-) i have only 'normal' /etc/fstab .

# /etc/fstab: static file system information.

i have not currupted fstab. but i can tell what partition of external USB hdd was added in this file . it's a simply add in file like this

/dev/sdb1 /media/some vfat defaults,utf8,umask=007,uid=0,gid=46,auto,rw,nouser 0 1

it can thinking what i run disk management utilities and manually add partition of this HDD.
after loading os i disconnect my usb hdd and run this disk manager. in normal sutiation my external disk will not be here. i see only internal hdd. when i plug usb hdd he will be in this manager. after unplug he will not see here. but here i see: hdd is not present(it's ok) but record about this disk is present. and when i run konqueror then normally i can see my hard disk devices as "hard disk <volume>Gb" (or some thing. i dont know what is like in english version). but here i see names of this partiton "sda1", "sda2"... i correct manually /etc/fstab by deleting wrong string (only external hdd) and reboot. my computer after it was good :-) and all ok
