Wrote incorrect partition structure to disk, now inaccessible?

#1 Post by toque »

in an attempt to recover files on my recently cleaned HDD, I accidentally selected EFI-GPT partition map and went through Analyse>Quick Search>'P MS Data'>Write. Now when I try to access the drive it says "D: is not accessible, access is denied.". Ive already went through the same process but with the Intel/PC partition but that only gives me "D: is not accessible, the device is not ready.". At this pooint I don't care about the files I was originally trying to recover, I just want whats on the drive currently. I tried to recover the drive using the method which I believe to be correct and I can see all the files still there, only most come out corrupted and unorganized. With such a simple mistake I'm hopeful that I can revert the changes I made easily. I went back to the EFI GPT partition and when I check my disk management, I can see that the files there are still taking up space on the drive so that keeps me optimistic.

Any help would be appreciated:)

After Quick Search, use Deeper Search. For each partition, use 'p' to list the files.
Use the arrow keys to set the partition you want to recover as P(rimary).
On next screen, choose Write, confirm, Quit and restart your computer.

Thanks for the quick reply, after the deeper search I get this message,

The drive I've been trying to recover is 1TB, do I need a seperate drive to write to? I really don't know too much more than basic windows partitioning so I really appreciate the help.
