I used ddrescue many times for failing HDDs with MBR partition tables. It always worked perfectly and if the failing HDD was bootable, the clone booted, too.

Now I have a possibly failing SSD, but this time it is GPT / UEFI bootable. Will ddrescue work for me? Will the clone work and boot correctly? Couldn't find anything about GPT/UEFI compatibility in the docs.

If not, what alternative(s) do I have? As far as I know, clonezilla is GPT/UEFI compatible, but I'm not sure if it will work for a failing drive.

  • Yes, a cloned copy works also with GPT and/or UEFI. Please remember to connect only one identical drive when booting (so either the original drive or the cloned drive, but not both). Clonezilla works too, and I prefer it, except when ddrescue is necessary to recover sectors that are difficult to read.
