Its not the BIOS, since it is updated to thew newsest, and it is seeing other drives as correct size. The drives that are over 100GB, it lists them as like 13xxxxMB blach blach, but then just under that it reads the actual size as 233xxx with however much free space. The drive I am trying to install on is also listed as 13xxxx(although not the same number as the other 2 drives, the other 2 are 250's, this is a 300)but then under it it still only reads like 131xxxMB.
