I tried this, but it isn't working for me.

I downloaded SystemRescueCd  ---> http://www.sysresccd.org/SystemRescueCd
I booted from a DVD and went straight to the GUI, had terminal open, typed in exactly what is written in the OP and I get an error in terminal.

After I type the part with "sudo ....."
Terminal responds with:

zsh: correct 'sudo' to '_sudo' [nyae]?

If I press y: _arguments:comparguments:312:can only be called from completion function
If I press n: zsh: command not found : sudo

I have 4 hard-drives and 1 SSD. I disconnected all of them and connected the 1 hard-drive that I need to run the recovery tool on (this HDD is not bootable). It's not connected to the number 1 SATA port on the mobo. Does this therefore affect the part of the code with:  '/dev/sda'? Or what's going on?

A bit of a bother especially when you've ended up in a thread here from Google and you need to make a comment about a technical issue. 

Yup, I donated/bought during the THQ humble bundle. Around $5 and it included Saints Row 3.

Didn't think so.

So then what are your recommendations, and why?

And does this poll do anything positive for those who have yet to choose a bitcoin client? Would a solid majority vote be a reliable endorsement for that particular client?

Hello,

Would like to get whitelisted to provide feedback to both the author of DiabloMiner as well as post in the "Bitcoin private key/wallet.dat data recovery tool!" since I did unfortunately lose a wallet.

Why hello there!

My mining setup:

7870GHz Edition (OC'd Core 1100MHz)
Diablo Miner ~392 Mhash/s

Flags are -v 1 -w 256 ... which were recommended in the Diablo Miner thread's OP.
I feel like I should be getting more Mhash/s though 

IIRC, these are very similar numbers to what my old 6970 was getting.
