While making my USB bootable for the installation of UBUNTU using Disk Startup Tool in Ubuntu 12.04 LTS, the process was cancelled and disconnected my external hard disk from the laptop(The source file (.iso) was in the external hard disk). When connected back, it shows neither files nor folders which was already in HD, but only few files with unknown format. Its names are seen as Greek letters.

When I checked in Windows, the total used memory space of the Drive shows unchanged, but memory of files show ‘zero bytes’.

For information:- External HD: 1 TB My Passport Ultra OS: Ubuntu 12.04 LTS Laptop: Dell Inspiron N4050

Please help me to solve the issue.

  • specify the filesystem type, whether it is ntfs or fat32 or something else.

  • This may be a corrupted file system. What does fsck have to say about it? Nov 12, 2014 at 16:26

It seems as if the data has been corrupted somehow.

From your Ubuntu 12.04, try running a fsck on the external drive.

Install Dosfsck with the following command:

sudo apt-get install dosfstools

Find the partition you want to 'repair' with mount. Then unmount the partition by running
sudo umount /dev/sdc1
(replacing /dev/sdc1 with the mount point of your device).

Then you can verify and repair the partition with
sudo dosfsck -t -a -w /dev/sdc1
(replacing /dev/sdc1 with the mount point of your device).

If this fails to repair the partition, you can try recovering the files from the partition with a utility such as TestDisk. Which you can read more about here: http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step

  • I get these messages when I run the above commands:"fsck from util-linux 2.20.1 -t and -w require -a or -r". What does it mean?

  • Basil, did you run 'sudo dosfsck -t -a -w /dev/sdc1' (with the correct device of course)? The message you're getting means it's missing the -a argument.
