That's all I meant, the machine with the borked disk, to distinguish it from the machine that was going to be the destination of your emergency backup. >(and when I say primary it's not the disk with the OS) You spoke of a secondary disk in your last email, as a backup destination. I hope to hell you're not thinking of copying to the disk with your OS on it. > >2nd thing is what do you mean by copy files, like I said the >filesystem is unstable/corrupted a little(or something like that), and >ddrescue doesn't seem to be capable of assisting here in this regard > >So I think that the main problem is how to extract files/fix the >filesystem from that rsd3i image that I have backed up now? Yes, that will be a savage problem. I don't know where on the disk the 73GB got copied, so I can't be any help there. > also is it >safe to format the primary disk (ssd) now? No. Nobody can perfectly reverse engineer your situation and nobody has a crystal ball. I'd leave that SSD intact, stored outside the machine, for a year. Once you format it you can never again go back and query it. >as I said the size is >different after I DDd to the HDD, it's much bigger than the corrupted >image... and I don't think that I can do a hash-sum of the image, can >I?

Get the disk image, as a file that can be loop-mounted, on at least one known good drive, and go on from there. Keep that borked DVD in a box somewhere for the next year when you finally power down the machine. SteveT Steve Litt http://444domains.com
