Hello.
I have a 1TB USB external hard drive, to which, I had been making
backups from different computers, and, to which HDD, I had also moved
some data, to free up system storage.
I unplugged the HDD from one computer, after having shut the computer
down, to get some hardware work done on the computer.
When I reconnected the HDD to the computer, the HDD could not be read
- I got an error message
"Error mounting: mount: /dev/sdb1: can't read superblock"
I get that error when I try to read the HDD, using the file managers,
and, when I try to mount the HDD, using the file managers.
I have tried to access the HDD from different computers (plugging it
in before booting, then, booting the computer, and trying to access
the HDD via the file managers, which each return the same error), with
both Debian 6.x, from which it was last successfully accessed, and,
this installation of Debian 7.5 xfce; each is Debian amd64.
The device still shows in lshw; giving, on Debian 7.5,
"

"
Is a utility available in Debian Linux, to overcome the superblock
problem, so as to allow me to resume accessing the data on the USB
external HDD?
Thank you in anticipation.
