ddrescue RAID
 

Hello,
I have a server with hardware RAID so both drives show up as a single volume.
If I create a clone of this with ddrescue to a single disk, then ddrescue it back, will it still be bootable? I did attempt to boot the single disk on another computer but it failed so I'm a bit concerned whether my clone is any good.

If you boot to some new live media and that distro also fully reads the hardware (and not faux) raid then any task you tell it to do should get the data as if it were a real single hard drive.

Are you sure you have a real hardware raid card?

And what raid level?

ddrescue suggests to me that you know there is major damage.

How far do you get with testdisk?

I did ddrescue simply because it was what I was trained on. I'll get the exact error for you when I go back to the office.
It is indeed a hardware RAID card. Booting up the machine prompts me to push a button to configure RAID. I've also opened the machine and see a RAID card in there.
