I've tried to reactivate it numerous times, plugged it into different SATA cables, used different power cables and restarted in between everything. I also tried reactivating it through cmd prompt but to no avail.
Looking at the pic it looks like you tried to make the new disc an dynamic extended disk to make you video partition larger.
Is that what you wanted to do? If not you should be able to right click on the missing disk and click enable, or online. At that point delete the partition and recreate the parition as a simple disk.
No it wasn't linked with the Video disk at first. For the last 4 months I have been using it as a drive by itself, it has its own info on it. The only options I have if I right click it is reactivate or delete, clicking reactivate does nothing and I do not want to delete it as it still has all my stuff on it (at least I am hoping)
