From your link it looks like it is unformatted.
Have you used it before ?
Is it new ?
Has it been used on another o/s ?

Open synaptic package manager and search for
"ntfs-3g'.

If it is not installed then install it.
It will give you read-write capability for ntfs(windows) formatted drives.

You may need to reboot after installing but try logging out and back in first.

The reason it appears unformatted in your link is probably the lack of ntfs-3g in your ubuntu install and thus not being able to see the drives file system.


Edit. I just saw that you have used it on Ubuntu before. (was it this install /)
It is possibly that it was not cleanly unmounted at some point. (like removing the usb connector without unmounting first)
Try accessing it in Windows then use the 'safely remove' option in windows to cleanly unmount it and then try it in Ubuntu.

So the last time you used the drive was under Windows.
Does sound as though it was not unmounted cleanly there so re-attaching it to a Win box and then unmounting seems the best and simplest option at this stage.

Other things I would try would be to do an update on your Ubuntu box, especially as
haven't used this comp in month .
Reboot and see if that helps.

link to Ubuntu Community Documentation.
https://help.ubuntu.com/community/Mount/USB

and scroll down to "Manually mounting" Then "troubleshooting" and read the whole document before doing anything so you are aware of what you are doing.

I would be trying the Windows access and safely remove first and that would also see if there are problems with Win too and if the drive may have problems being seen by both o/s.

Still a no go :( sadly. Do you suggest formating it?(Hard for me to even type that, with all of its important contents)

No.


What did

sudo fdisk -l
and

mount
return ?.

and after plugging in your drive run

dmesg
and post the last few lines of that too.

(I am preparing for guests so will be checking intermittently, hope someone else can jump in to help too)

Did you try plugging in to Windows ?
