Can't open filesystem. Filesystem seems damaged.

#1 Post by user436 »

I have an old 320 GB Transcend external hard drive that gives me the "You need to format the disk in drive..." error message when I plug it in. It seems to list the files correctly but when I try to copy them to another location I get the "Can't open filesystem. Filesystem seems damaged." error even though it lists the partition correctly the first time. What can I do? Thanks!

Run TestDisk, Advanced, Boot, RebuildBS, List. If you see your files, choose Write, confirm, Quit and restart your computer.
If it doesn't work,
- run "cmd" (right click run as administrator) and "chkdsk /f d:" (replace d: by the correct drive letter)
- you can also use PhotoRec to recover your files but unfortunately without the original filenames.
