I have a 1.5 TB hard drive of seagate , I was copying some files and it froze , i tried 2-3 times but still the issue was there , so then I ran a hard disk error tool of the windows 7 . Left it overnight and found that it froze too . Now my hard drive is no getting detected , i cant see in the disk management too . Some times when I see it in disk manage ment it shows 0 bytes and hard disk not initialised status , Please help .
