I've been using an external hard drive tonight,with a USB connection
I ran into a permissions issue: the drive mounted at /media/<user>/<partition name>
but didni't pickup my permissions -- rather -- it was owned by root
I fixed it by navigating to /media/<user/ and then issuing a
sudo chown -R <user> <partition name>
I'll have to do it every time I use the disc -- but -- that's OK -- it's an offsite backup disc
still -- it occurs to me -- on SD chips, and thumb drives -- these are usually FAT32 devices -- and have no permissions
the external hard drive -- the partition -- i formatted it as ext4
when SD chips or thumb drives are mounted -- Debian does not ask for authentication. but when an internal drive is mounted -- it does -- and ends up with the right user
when the ext4 partition is mounted via USB -- again -- the system does not ask to authenticate.
is there a bad test here? i.e. does the system determine not to ask for authentication based on the use of the USB bus -- rather than the type of partition ??
