OT: Hard Drive Data recovery using DDRescue
So I knew that DD Rescue on Linux was good at data recovery, but it has been a long time since I have used it so I'm just a beginner. Ian has used it a lot and knows lots of tricks to maximizing data recovery from hard drives. I have a hard drive that was with my desktop since 2011, so it has seen a lot of use. It is in the process of failing. Ian used the command like this: ddrescue -v -v -d /dev/sde3 salvage.img salvage.log He can explain a little better about what it is doing with these switches, but this way you can stop the process and pick up where you left off and it will continue. It uses the log file to keep track of things. So I ran the process which took about 36 hours or so. In the end I recovered 99.99% of my data with 40MB lost. Pretty amazing! It recovered almost all of the 1.4 Terabytes of data with about 40MB of sectors with errors. Pretty amazing! To recover a little about another 3MB of data, I had to unplug and restart the drive because it seemed to lock up. Then I ran another command to work from the end of the disk going backwards and to try 5 times to recover as much data as possible that had errors in the sectors. This was the command used: ddrescue -v -v -d -r5 -R /dev/sde3 salvage.img salvage.log On the windows 10 side I used OSFMount to mount the image and then copy to another hard drive. Thanks to Ian for helping me with the commands and to Jonthan Sturges for lending the cable to connect to my computer. I would have lost it all without your help. It's truly amazing! Other commands used were: mkdir /mnt/test mount -o loop,ro salvage.img /mnt/test Maybe Ian can fill in more details about the process. -- ========================================= Jeff Brace Vice President & Board Member, VCF East Showrunner Vintage Computer Federation http://www.vcfed.org/ jeffrey@vcfed.org
