Partion Recovery

#1 Post by hrzboy »

I have a 1TB harddisk.Firstly,I have 180GB free space in the end of disk.
So I decide to extract 150GB out to install a windows 10 64bit.
But when I tried to do so by windows disk tool and diskgenius.There was no selection to do this.
And I found out that the Partion Qualifier is 42 as Raid.I've never have same model harddisks,and hardly remember that I have ever set up the Raid.
So I manually change it back into 07 ntfs in diskgenius and applied the change.
At first it was alright,so I then extract 150g free space out.
And then when I boot the xp from another harddisk 500GB,I found that I was not able to read the data on this 1TB harddisk.
It shows unallocated.And the 150G is able to be use,and accidently be wrote some file.
Then I found TestDisk,seems my only hope.
I tried many operations,seems the only work way is to select Intel selection and deep analyze.
After anaylyzing about 6%,it discovered the right partion but the size is bigger than original and won't apply.
So what can I do to apply it?

the png is missing. Can you copy/paste the testdisk.log file content ?
Try Deeper Search if you can't recover your partition after Quick Search.

Can you try with EFI GPT as partition table type ?
