I have ubuntu and windows on my laptop. I have a separate NTFS partition which I use for storing my files. I have been using Ubutu for read/write to the ntfs partition for a long time. 3 days ago I booted the windows and just opened the ntfs partition without writing any files. Once back in Ubuntu, I realized that some of the directories in the ntfs partition are gone! When I ls into the partition I get input/output error for those directories. The directories do not appear in windows also.
I have already made an image on the partition using ddrescue.
I have tested these with no success: testdisk, ntfsundelete, foremost under Ubuntu and chsdsk under windows
I appreciate any help to recover the data
