Windows 7 x64 - Hardware 4x500GB RAID 5 - Limited Drive Capacity
Greetings!
I recently installed four 500GB HDDs and setup a RAID 5. After formatting, etc, I see what I expected: 1,430,812 MB.
Now... Here's the problem. The partition shows it's set to 1.4GB... but only shows a drive capacity of *one* drive. This goes for Disk Management as well: Disk 0: Basic; 1397.28GB; Online; NTFS; Capacity: 465.76 GB.
I completed a chkdsk /r, tried looking at the partition with other software (Acronis, Partition Magic, GParted), and they all show the same thing: a single partition covering the span of the drive, but only a capacity of 465.76 GB.
Thoughts?

That is how it is supposed to work. You have one LOGICAL disk that represents those 4 disks combined for redundancy.

I was under the impression it was striped, with one for parity, so i'd have a full capacity of 1.4GB

Oh, I see. Thanks!
My assumption was that you are using a RAID controller. Are you using windows native dynamic disk software RAID only? and then booting to another disk? Please elaborate
A raid 5 array with 3 500GB disks would put you at about 1TB. You should be getting at least that much. In disk managment are you able to see the extra space as blank? If so, you can format it for a second partition of the rest of your space?
Also, it might be helpful if you could attach a picture of your disk managment screen

I'm using the RAID controller on my mb: Intel DG965WH
