This is why I generally don't give technical advice.

It looks like the the original partition info, filing system and mft were totally overwritten/destroyed. I think you are wasting your time trying to get back any file names or folder structure. The file system information you provided from Rstudio is only correct for the cloned drive. You are going to have to recover raw files without any structure.

Though if the file system was originally something other than ntfs there might still be some hope to get some files back with original names.

There are still some unknowns to be clarified. The ORIGINAL partition information, filing system and raid type. Also how the accidental clone happened. Was it from usb to usb device or some other way/setup?

Ok, I've just ask him, and remembering... instead of making a backup, by error he completely cloned 50GB (48.8GB) of a partiotioned 80GB HDD. The remaining 30GB, he said not.
Program used to clone was macrium reflect.
((( Plus to consider that another friend of him have tried a recovery ...not clear what, difficult remember (happened last year) only the bad accident of power went out when he was using Recuva, then another guy seems help him to do something ........and at this point I think it's better to figure it out by my self, because there are too many passages :roll: )))

He said most important it's to recover this cloned 50GB, where was all photos etc... plus then other some important files on the rest of the 1TB, if possible.

Tomorrow morning I start DDRescue, and update here.
It's ok this guide? http://techmuck.blogspot.it/2012/03/data-recovery-with-gnu-ddrescue.html
....I don't understand, why I've to clone starting from 1TB point and not from the beggining of the HDD? ...I just like to learn. :)



hi bobhoskin!

Nothing to do in this case, overwriten data.

Ok, I'm back again... thanks guys :( your last posts don't give a lot of chance, but I ask help for something I can and have to try ...it cost some time and a new HDD of 2tb, I'm positive and hoping I can find something. :cry:

I've try to follow what Fzabkar suggest with DDrescue:
fzabkar wrote:.....mount them as a virtual RAID0 with a stripe size of 64KB (= 128 sectors). Then try to clone the RAID onto your 2TB drive.
For safety's sake, you might like to clone each drive, sector by sector, using ddrescue. Clone drive 0 to your 2TB drive by setting the 1TB point as the starting sector on your target. Then clone drive 1 using the 1.5TB point as the starting sector on the target. You need to ensure that the images don't overlap.

so I've made a bootable Linux/DDrescue USB drive with this: http://www.sysresccd.org/SystemRescueCd_Homepage

But the Usb pen it's not working, it boots up even if I choose the usb drive first in Bios etc.. than I see DDrescue it's not "point & click" but needs some attentions and study... I ask, there is another program that I can easly use on windows7 and make all the operations that Fzabkar suggested???

Otherwise I'll find time to study the DDrescue method.
