I'm not very expert and I have been struggling with my partition for 3 days now!
Basically I have this 2T hard drive where I accidentally cloned my main Win7 OS.
Then I changed my mind and I decided to format everything. After I decided to make 1 partition in the huge drive,but...
I started to have the problems: windows management is not up to date! So I'm running deep search at the moment, what I'm supposed to do after? I don't need any file, just my drive back as primary NFTS.
Later i tried to shrink my second 3T drive and didn't work as well I got mounting failed

So I was trying to fix the first drive to eventually recover all my files in the second drive saving them in the first.
Hope this make sense
Many thanks
