I have an older 640 GB hard drive. I installed a new internal 2 TB drive in an open bay/port. I was thinking I could use RAID 1 for the 640 drive and another partition to use the extra storage. Once I set up the RAID, the drive capacity of the 2TB drive changed to 640GB. I was not able to expand it.
I decided to break the RAID and I reformatted the drive using a USB docking station. I reinstalled the drive. The RAID is still broken, but I still cannot repartition or in any way get more capacity than 640GB on the 2TB drive.
I've tried:
Win 7 disk management--does not allow expansion above 640 GB
Intel Rapid Storage Technology--Shows the full capacity of the drive, no actions I can take
BIOS--Shows the drive as a 2TB, shows AHCI, not RAID
Tried MiniTool Partition Wizard--no help
I suppose I can use this drive in the docking station forever to get the full capacity, but that is ridiculous. Any ideas? I think there is something remaining in the BIOS or registry that is limitiing the drive size.
