Re: HDD no where???
The third one will infact be seen as the second.
It may be slightly complex, since RAID 1 works best with identical drives of the same volume/model.
What you have basically done is created a mirrored array using the smallest drive size, so 200GB; leaving one drive with an unused array of 65GB which may be unformated and unused if I'm not mistaken. You can check this if you right click on My Computer, and go to Manage, and then select Storage, and Disk Management on the side. The RAID 1 will still only appear as one drive, but if there is infact a third drive here now, of a size close to 65GB, you should be able to make it useable.
You could try formatting the third drive within Windows, by right clicking the drive and selecting 'Format...'. You will lose all data on the drive however.
