Only 1 HDD detected

[Cs342]

So I just installed Windows 7 on my SSD and then moved my 2 mechanical HDDs from my old rig to my new one for music and movies. Only 1 of them is detected by the OS, even though both of them show up in device manager. They were originally together as a RAID 0 array but I formatted the whole thing on my new rig as it said I could not use it without formatting first.

Did you assign a drive letter to it? Check Disk Management.

It doesn't show up in disk management, only device manager

[Cs342]

Oh it just showed up in disk manager for some reason, and is called "Disk ` - 931.51GB Unallocated". What do I do?

Do I just click "New Simple Volume"?

yes 

[Chris is awesome]

If it isn't the primary drive you can Right click > format and it should give you the options to give it a new name and assign it a file system.

For some reason the drive letter D is not available in the drop down list, even though none of my drives are assigned that letter
