I assume that the file "Backup Junio 2016" cannot be displayed/edited in both Windows and Ubuntu, and gives an error in both cases.
I assume that the disk is formatted/partitioned in GPT partition table format.
I assume that the disk has a NTFS partition on it, and that it's NOT a bootable Windows external disk. If that's the case, attach the disk while in Windows. Then open an administrative command prompt window, and type
chkdsk /f d: changing the "d" to the correct drive letter. This will correct any errors in the file system.
If it IS a bootable Windows external disk, then do this in Windows:
- open the Power control panel
- click on
change what the power buttons do
- click on
change options that are unavailable
- close the Power control panel
- open an administrative command prompt window
powercfg /h off (turns off hibernation)
chkdsk /f c:
- approve that chkdsk runs at next boot time
- reboot Windows
Attach the disk while in Ubuntu. Open the
Disks application from the Unity dashboard. Select the erroring disk in the left pane. Go to the "hamburger" icon in the top-right corner of the Disks window, and select
SMART Data & Tests. Observe the data, and run the tests, and see if SMART can tell you about the condition of the drive.
Then, assuming that the drive comes up as /dev/sdb (or /dev/sd_whatever), open a
terminal window and type
grep sdb /var/log/syslog* (or grep sd_whatever /var/log/syslog*) and look for disk errors. If you need help interpreting what you see, upload the output text to http://paste.ubuntu.com and give me the URL and I'll take a look for you.
