Hi, I am having the same problem as Rynkeby in https://www.techspot.com/vb/topic34363.html But my problem can't be resolved by using PTDD partition table doctor 3.0. My D drive in disk management is healthy but doesn't belong to any file system. When I use PTDD to view, the system file of NTFS is there!!! When I select fix boot, it says "Boot sector of the partition is right!" But in the disk management, I still unable to explore the D drive content. Can anyone help me out on this?? I need to get back my data urgently. Thanks.
