Undeleting Files Using mc

The Midnight Commander can make use of a virtual file system and includes a special undelete file system that can be used on ext2/3 partitions. The mc utility is just an interface to the ext2fs library, and the virtual file system handles for you the nitty-gritty details of the file system that the previous paragraph alluded to. As with any simplified solution to complex issues, mc must make some assumptions for you that might result in less data being recovered than if you use the manual method. For that reason, using mc for recovering deleted files is not a standard method.

To use the recovery file system, you must cd in one of the panels to the special filename formed by combining the prefix /#undel: with the partition name where your deleted file resides. For example, to attempt to recover a deleted file on /dev/hda2, do this:

sudo cd /#undel:hda2

Be patient because it will take quite a while for the deleted files to be displayed. You will see a list of inodes that you can examine with the text editor (using the F4 key); then use the F12 key to perform a Save As operation, renaming the file to something appropriate for your use. Repeat this process until you have renamed and saved all the files. Press the Shift+F10 key to exit when done. Note that you might be able to recover only pieces of files and might not be able to recover any at all.

Note

If you need to know what is on a drive or disk that cannot be easily mounted (it could be a non-Linux format, or could contain un-formatted, raw data), use sudo dd if=/dev/hda1 count=1 bs=512 | file which produces output similar to the following:

1+0 records in 1+0 records out standard input: x86 boot sector, \

system MSWIN4.1, FAT (16 bit)

To discover what an unknown floppy disk is, use this:

sudo dd if=/dev/fd0 count=1 bs=512 | file which produces output similar to the following:

1+0 records in 1+0 records out standard input: x86 boot sector, system )\
