I can no longer read or write or even unmounted a USB flash drive.
Something happened during the last two weeks. I am using squeeze and
regularly upgrade on a daily basis. The only change to the system I can
recall was debfoster run during that period where I deleted some 4 or
five libraries.

Hello,
Please provide more info, i.e. what does mount says when the USB stick
is plugged in? fdisk -l output would be helpful too. The ouput of tail
-f /var/log/messages when plugging in the USB stick can be informative
too.
Regards.
here is the aditional information.:
john@debian:~/Desktop$ umount /media/usb0
umount: /media/usb0 is not in the fstab (and you are not root)
john@debian:~/Desktop$ fdisk -l
bash: fdisk: command not found
john@debian:~/Desktop$ su

This doesn't look like a partition table
Probably you selected the wrong device.
