after partition recovery windows shows raw file system?!

[disaster]

Hi!

I have a WD MyBook Essential 1TB, which device somehow deleted the existing partition (there was only 1). I was able to recover all my files with R-Studio before using EASEUS Partition Master.
Now after the partition recovery - EASEUS told me it was successfull - the recovery softwers recognise my partition as an usual NTFS file system and both R-Studio and UFSExplorer can read the whole content without any further scans, but not the OS. It shows RAW file system.
How could be solved this issue? (without formatting, so I don't have to copy again 850GB data, since the MFT is probably ok)

Thanks in advance.



(firmware is the latest version, OS is win7)

Apparently, Partition Master has created the MBR of bootrecord of the disk incorrectly. My recommendation is strict - reformat the disk using Windows and copy the files back. It may be a lengthy process, but it's safe.
There are some measures in Windows that might heal the problem but I don't recommend you to use them, if you are interested in the result rather than in the process.
