Hello,
I was trying to backup some data from a Ubuntu 12.04 linux
installation when all of a sudden the external hard drive I was using
(My Passport 300Gb) changed to read only.I have spent about 2 hours
trying to set the permission back to read write without success.For
example I have tried the following command
sudo chmod 755 "/media/My Passport"
and
sudo chmod 777 "/media/My Passport"
the message given both times was
chmod: changing permissions of `/media/My Passport': Read-only file system
I'd also like to mention that I do not recommend Ubuntu 12.04 to anyone
as it has far too many bugs to be usable.Linux Mint is much better for
example.
I hope someone can help me to get my external drive back to read write mode.
regards Peter
hi
I need some help with this simple bash script, I ran the script twice,
the first time it failed on some bash arithmetic, I then ran it again
without changing anything and it worked, so I slightly puzzled as lines
8&11 are the same and sometimes it evaluates it and sometimes not.
