ddrescue Recovery Notes

Notes on the command ddrescue. In my case mostly for recovering a drive to a healthy one but can also be used with files. You can use SystemRescueCD to boot & run.

ddrescue command example

ddrescue -r3 -n -N -v /dev/sda /dev/sdb logfile.log -f

	^ -rN, --retry-passes N
	  -n, --no-scrape (scraping and trimming may take extreme amounts of time (months)).
	  -N, --no-trim
	  -v, --verbose
	  -f, --force (ignored for regular files, confirms that you want to overwrite dest disk/part)
