Windows 7, 64 bit OS
Disk 0: 300GB for OS
Disk 1: 2TB for storage
Disk 2: 4TB for media storage
Disk 3: 4TB for backup of media
Disk 3 is new. I recently reimaged my computer back to my factory settings image. I formatted Disk 2 and installed Disk 3. I planned to have it running with RAID 1 but discovered much to my dismay that Windows 7 doesn't support RAID 1 and nor does my bios. I resigned to having a simple backup system instead for the time being and reinstalled all the software I wanted to keep.
Prior to the reimage, Disk 2 was seen and used by windows as a 4TB hard drive.
When I reformatted the disk I mistakenly selected MBR and started copying my data back across. I hit the limit and realised that I had initialised both disks into MBR. After looking through the web I found how to clean the disks through Diskpart on CMD and then reinitialise them into GPT. However, this has not fixed the problem at all. I still have a massively frustrating limit on size of 1677.90GB for both drives. See picture.
I am really finding this frustrating. All the advice online says to convert the disk to GPT and it will fix the issue. They are both now of GPT. Prior to the reimage Disk 2 was seen by the computer as having 4TB (well more like 3.6TB) so I cannot believe that suddenly the BIOS is creating an issue. I don't know what to do.
How do I make Windows see the disks for their true size? Thank you.
