Hello,

I have a Hitachi 3tb drive. Power supply was shorted out and corrupted drive. I had 2.2tb of data on drive, thus 800gb free. I recovered my data(through data rescue 3), then when I went to reformat the drive it will only format the 800gb that was free.

My question is, how do I format the entire drive? I have tried PTDD for windows, I have boxes that run LINUX, OSX, and 7. So if anyone knows of a base layer format tool that can get past a corrupted partition table please let me know.

I am also confused how I could recover the data, but not be able to format it.

You could try runnning cmd as admin in win7 & then run diskpart. Select the correct disk & then run the clean command or run the clean all command to zero wipe the entire drive but it will take ages for a 3tb drive. Then try formatting it again.

Basic commands are
List disk
Select disk
List partition
Select partition
Clean
Clean all
Create partition primary
Active
Assign
