I have a PC with Intel ICH10r running RAID 1, originally with two 500GB drives. One of the drives failed, so I took the opportunity to upgrade to two 2TB drives. I rebuilt to one of the 2TB drives then installed the second 2TB drive and rebuilt to it. After that, I was able to expand the volume, but only to 839GB. Both drives are showing to have 1,863GB capacity but I cannot expand the volume farther. I have since upgraded ICH10r drivers and searched for BIOS and firmware upgrades for any-and-every piece of hardware on earth!
Does anyone have any ideas? I would hate to rebuild from scratch and reinstall the OS(Win 7 64 bit) but I will if that will solve the problem.
