I have a SATA HDD that's failing. After several attempts, my USB adapter was able to recognize it. I'd like to create a disk image, so that I can clone it when my new drive arrives. What's the best procedure to accomplish this?
It is possible that the hard drive has bad sectors, so you can secotrs to a healthy hard drive using WinHex or partitionguru, so that you can skip bad sectors and copy sectors that have files. http://www.eassos.com/partitionguru.php
Ddrescue is recommended by data recovery professionals. You can run it from a Ubuntu Rescue Remix CD. It's not the most user friendly solution, but it has numerous features that are designed to work around bad sectors. It also keeps a log so that it can resume after an interruption.
