So I followed your advice and checked it out. How do I use an "unallocated space" partition in Windows 7? Nema98, please follow the instructions at the below link to start up Disk Manager, to see what size your C drive is, and how much space was left unallocated on your Disk 0? It may be that someone really screwed up his hard drive, and made a C partition with only 6GB, and left the remaining 634GB as unallocated? Nema98, is that the case? Do you have a USB thumb drive plugged into a USB port on your laptop? It sounds more like the D drive is a USB thumb drive? So it doesn't sound like the D drive is a partition on the hard-drive. The OP previously said his D drive was a removable disk. I would highly recommend running diagnostics on the hard drive to see if it has a physical defect before doing that, as a defect would explain why chkdsk is constantly being run. The solution to your issue is simple, Assuming Windows 7, you can use disk management to delete the D partition and give the resulting free space to C. C is not a disk, it's a partition on the hard drive, same thing for D, it is partitioned just like I said it was a number of posts back.
