Under the computer tab in Windows 7 Pro 64bits I only see the SDD on my new build and not the 3 HDD's that are attached also. Do I need to go to the command prompt and enter ......DISKPART commands and setup each drives manually or reset CMOS? Also, the drive that I see does not show the max GB of the drives as 256 GB. It show the drive max GB of 238 GB and 216 GB free. Is there something I needed to do to change the drive's size?


1. Using the SSD for Boot/OS/Programs....drive is setup and Windows 7 PRO 64bit is loaded

The next thing I would like to do is get the drives to show so I can do the following:

2. Using the 2 TB HDD in RAID1 for libraries (data/media, my DOCS, Music, Pics, etc.)
3. Using the 1 TB external HDD for backup-Microsoft Sync and Norton backup Utilities

Please Help!!!

Go to Windows Disk Management and your missing drives should be visible.
Initialize the drives, assign them drive letters, and Quick format them. They will then be ready to use.

Since you are creating a RAID-1 array you should not do what I mentioned above to your 2 1TB HDDs until after you create the array in your motherboard's BIOS.

Your SSD should be connected to port SATA3_0 or SATA3_1.
Your HDDs should be connected to ports SATA2_2 & SATA2_3.

SSD & HDD manufacturers calculate 1 Gigabyte as 1,000,000,000 bytes (Base-10 numeral system).
Microsoft and memory RAM manufacturers calculate 1 Gigabyte as 1,073,741,824 bytes (Binary numeral system).

The difference between the 2 methods is 7%.
So when you buy any size SSD or HDD you subtract 7% of the advertised capacity and that will be your formatted capacity in Windows.

7% of 256 is 17.92; so that's why you see 238GB in Windows.
