I'm trying to make a f***ing back up of a back up. I've read nearly all of the post's in this forum for help, but still no f***ing joy. I'm using a LG CD re-writer, and have managed to burn both the boot CD And the US browser disc, but i can't make a BACK UP OF A BACK UP!!!
I'm using disk juggler 3 and using the following settings
select cd-cd
goto advanced.
check 'ignore read errors'
check 'raw read/write'
But when it comes to writing, i get the message illegal field in command block, i've put the jinxter driver but it still wont F***king work
Please can someone help before I theough this B**tard computer through my window

Cheers
