i have 1 tb hard disk my problem is that i am getting a error saying that I NEED TO FORMAT MY HARD DISK

Hi there, If you are having that error on windows, you will have to format otherwise windows is not going to let you use the drive again.-

Sometimes TestDisk  http://www.cgsecurity.org/wiki/TestDisk will fix a corrupt partition or drive.


But their is no problem with the hard drive, till last night I use my hard drive to transfer some movie till then it was OK today morning when I try to connect it start showing that error

and I have to much of data in that hard drive I can’t format is their ant other option

currently I put my hard drive for scan I downloaded a software form WD support “DATA LIFE GARD TOOL”  and scan is going on does that scan going to help me in any way

That will only show if you have bad sectors on the drive. Maybe this will be simpler than TestDisk http://www.easeus.com/partition-recovery/ I’ve seen this recommended by a few people too. They make good productys. I suspect your partition data is corrupt.
