Print location of deleted file on disk #93

Closed maltfield closed 4 years ago

maltfield commented 4 years ago

Feature Request: Please add the ability to print the location on disk where a deleted file's bytes lived/live.

Why?

Consider the case where a user accidentally rm'd a file when they actually meant to securely delete it (with srm or shred, for example).

Testdisk can help find that file, but currently it can only restore it (which, in this case, would actually make the issue worse since it may not be restored to the same physical location on-disk).

But if testdisk had a way to simply print the location where the file used to live on-disk, then a user would be able to take this information to another tool and securely overwrite the disk where a deleted file was insecurely deleted.

When running TestDisk, choose to create a log file, in Advanced, list the files. The inode number is recorded in the log file. Example:

Directory /
