Hi! I have a 1TB hard drive partitions into a C drive and D drive. The operating system is Windows 7 64 bit.

The C drive is my every day stuff, and I use D to store media, music, video etc. Today I wanted to access the D drive and it was not there. The C drive is listed as usual.

I went to Disk Management and the missing D drive was not there as well.

I don't know if this explains things, but I ran a partition analysis program and it showed 500 gigs as unallocated. But that space is also not noted in disk management.

Right now Im running partition recovery software to see if the files are somewhere, but it will take a few hours.

Any idea what is going on?
