Bug#697327: installation-reports: Can not write on usb flash memory

[jswmb01x <jswmb01x@mobistarmail.be>]

The problem appeared after the installation, when I tried to use the USB flash memory.

In fact the question is more "Why were those three lines generated in the /etc/fstab file".
Commenting them out fixed the problem, without any addition of package (one can find a lot of opinions when browsing the web about similar problem !) As mentionned in the first mail, I most probably left some USB flash connected on their ports while installing wheezy from the CD.

As a first approach I tried to change the access rights and ownership of the files on the USB flash, but could not, even under root (!?); maybe I did something wrong.
Here below the access rights :
root? 
root? ls -l /dev/sdb*
brw-rw---T 1 root floppy 8, 16 jan  4 16:46 /dev/sdb
brw-rw---T 1 root floppy 8, 17 jan  4 16:46 /dev/sdb1
brw-rw---T 1 root floppy 8, 18 jan  4 16:46 /dev/sdb2
brw-rw---T 1 root floppy 8, 19 jan  4 16:46 /dev/sdb3
root? 
root? ls -l /media
