Hi Jim,

You could try as the root user changing the permissions of /media/backup.

# chmod 777 /media/backup

and see if this works.

so there must be a reson why it is only mounted read-only

again:
what does "dmesg" say or what appears in /var/log/messages
after trying tou remount RW - it is laways the same: without
providing any information nobody can help you








mount -o remount,rw /



sda3 is /

well so what let you come to the conclusion it is MOUNTED read-only?
what says "mount | grep sda3"?

i doubt you are only kacing write-permissions
this has nothing to do with read-only

is this still the same computer of your freind
where you trying to rescue data since days?

if yes - PLEASE be a friend to him and consult someone which
is knowing what he is doing - appearently you are only shooting
in the dark which sooner or later ends in data finally lost!

as said , the disk is NOT read-only
why are you ignoring the hint to lacking permissions?
why do you not provide any useful outputs?

WHAt is the error-message you get?
what is the uncutted input and output in your terminal?
as which user you are calling whatever commands?
what are the permissions of what ever you trying to access?

WHY IN THE WORLD DO YOU NOT PROVIDE ANY USEFUL INFORMATION
WITHOUT SOMEBODY GIVE YOU EXACT COMMANDS?

really, we are not here to guess what you are doing

if you think you do not need provide informations
without requesting them you are wrong on a mailing
list - this way you can act with a book but not with
people wasting their time trying to help you!

This extra thread is sort of ridiculous. In the previous thread you've
shown already that /media/backup is a separate mount point:

> mount | grep sdb1
> /dev/sdb1 on /media/backup type ext4
> (ro,relatime,seclabel,errors=continue,data=ordered )

Now you try to remount /, which makes no sense because you would need
to (re)mount /media/backup properly. Not /. You could avoid confusion
like this if you provided enough details in all your posts rather than
letting list members do the tedious guess-work.
