Recover a damaged file from a defective disk.
Syntax
RECOVER [drive:][path]filename
You must specify a filename.
Recover is designed to help in the case of hardware failure. When a drive fails the failure is not always total, you can often read some files but not others, and some files will be only partly
readable.
The data on a disk is stored in tracks and sectors in an almost random manner.
RECOVER reads a file sector by sector and recovers data from the good sectors, data stored in a bad sectors cannot be read so this will often result in a partial recovery with some data loss. Restoring a backup is almost always a better option.
Recover does not allow you to undelete a file.
