I am using Ubuntu 12.04 with the Xubuntu Desktop package installed and am having problems with an internal NTFS hard drive.
Entire directories seem to be emptied without warning or going to the waste basket. This has been happening for at least a couple of months; I first noticed a problem when music files weren't being read into the library by Rhythmbox but assumed it was a Rhythmbox problem.
I've now noticed that a directory with nearly 500GB of files/sub-directories has been emptied. The strange thing, however, is that the drive isn't showing an increase in the amount of free space it has - as though the files are still there.
When doing an
ls of the specific folder that seems to be emptied, I receive an input/output error, but can
ls the root of the drive fine.
I don't have Windows installed on this machine either, and most of the other related questions seem to be related to dual booting Windows.
Any ideas on the cause of the problem and how to fix it?
