(description
|
|
"GNU Ddrescue is a data recovery tool. It copies data from one
|
|
file or block device (e.g., hard disk, CD-ROM) to another, trying hard to
|
|
rescue data in case of read errors.
|
|
|
|
The basic operation of Ddrescue is fully automatic. That is, you don't
|
|
have to wait for an error, stop the program, read the log, run it in
|
|
reverse mode, etc.
|
|
|
|
If you use the logfile feature of Ddrescue, the data is rescued very
|
|
efficiently (only the needed blocks are read). Also, you can interrupt
|
|
the rescue at any time and resume it later at the same point.
|
|
|
|
Automatic merging of backups: If you have two or more damaged copies of
|
|
a file and run Ddrescue on all of them, one at a time, with the same
|
|
output file, you will probably obtain a complete and error-free file.")
