Tool: ddrescue Source: SystemRescueCD

1. Download the SystemRescueCD from Download - SystemRescueCd systemrescuecd-x86-4.2.0.iso 380MB and create a bootable pendrive with that ISO using Rufus Rufus - Create bootable USB drives the easy way

2. Boot your computer with that pen drive with your source disk (your failing disk) and a destination disk (formatted empty disk of capacity not less than that of your source disk) plugged in.

3.Against the command prompt type: fdisk -l [ENTER] This will list all your drives. Note the nomenclature of your source disk and destination disk.

4. Next against the command prompt type: ddrescue -r3 -n -S -v /dev/sdb /dev/sdc recovery.log [ENTER]

Note: Replace sdb and sdc with the correct device nomenclature of Source disk and Destination disk as obtained in step 3.

5. Sit back and relax. The cloning process may take days depending upon how bad your Source disk is. If your data is important patience is the key and the wait worth it. The saving grace is you can stop the process any time with Ctrl -C and then restart. It will take the cue from the log file and start from where it left.

In the cloning process itself it will go through cloning all the good sectors first and then try to recover the bad sectors one by one trying it 3 times (r3 option) before giving up on it.

I have actually tried it cloning an 8GB pen drive with bootable Peppermint Linux ( that was created sometime back on a request from Golden to try it and report ) onto a 32GB freshly formatted pen drive. It took about half an hour. At the end of the cloning I was able to boot into Peppermint from that cloned drive which signified successful sector by sector cloning including the boot sector/s.

May be Anshad Edavana will be able to polish it and improve upon it as one who had actually tried it on a failing disk. ( As indicated already I had no failing disk.)


Hey guys,

So, Im going to take a shot at this and had some questions:

1. is this still the best set of instructions, and command to use?

2. am i able to boot from the external hard drive that i make this image to, or some change needs to occur before i do that? (i.e. linux filesystem to windows filesystem conversion, or some other requirement)

3. after i make this image (assuming it completes), what exactly am i going to do with R-studio to recover the bad sectors?

4. do i need to format the external harddrive in a certain way/format before i begin this?

5. I would like to do this from a failing SSHD (hybrid), to a external HDD using a USB cable. Is it still the same set of instructions?

6. A little off topic but, if i leave the bad drive installed for now, in UEFI can i stop it from getting mounted on boot?

7. Another Off topic question, before the failing SSHD diagnostics i copied over a 60GB directory from a an old PC. within that directory there were various subdirectories not showing correct file names/paths. could this large/old directory somehow have caused or resulted from the SSHD to go bad?

Thanks!

Is ddrescue not the best way to go about this anymore?

HDD Raw Copy

There is an awesome, free program from HDDGuru.com called HDD Raw Copy Tool. It runs from within Windows and will do a sector by sector copy, automatically skipping bad sectors. I have found it useful when a source disk is too badly corrupted for most conventional cloning programs to handle. This program also allows you to backup a whole drive or partition and restore from the image.
