Files Recovered are damaged

#1 Post by omega11 » 07 Jul 2015, 06:50

Hello,

I loose more than 100 GB of data (music, videos, images, documents, pdf, doc, etc.) in strange circumstance, I share partition (NTFS) only for share data between Linux (Debian 8) and Windows (Windows 7). After use Windows I reboot and start Linux when I tried to mount the share partition I get error like Windows is yet using. I reboot and start Windows my surprise when windows started was that the share partition was empty all my data loose it.

After that I come back to Linux and use Photorec to recover files. Photorec took more than 24 hours for complete the task and recover more than 500,000 files. Here my second surprise only some jpg, png and mp3 were recovered. All others files (doc, pdf, docx, odt, txt, html, php, css, djvu, avi, mkv, etc. etc.) are damaged.

Is there any form that can I repair the recovered files?

P.D.: No suggest me search in internet. I have more than 24 hours searching and not found any that work.

Thanks in advance!

I will appreciate any help!

Can you run a diagnose using testdisk?
You should run Analyse, Quick Search and if nothing would be found, Deeper Search also.
If partitions are found, please slect them and press p to have a try to list your files.
TestDisk creates a testdisk.log file.
Cna you open it and copy and paste the content into your next post?
