Cannot Create RAID 1 Volume
I have a Dell XPS 8700 running Windows 7 Professional 64-bit. It came equipped with one 2TB hard drive (Seagate 7200 RPM SATA Hard Drive + Intel SRT 32GB SSD Cache). I bought a second identical hard drive and want to create a RAID 1 (Mirroring) Volume. I physically installed it and the system recognizes the drive.
The configuration utility (CNTL-I on bootup) shows the second hard drive, but the options to Create RAID Volume and Delete RAID Volume are greyed out. The utility shows the original hard drive is accelerated and a 29.8GB Dev_Cache RAID 0 Volume is present.
This is the display in Control Panel/Disk Management:
When I right click in one of the Primary Partitions in Disk 0 and select "Add Mirror", the following message appears: "The operation you selected will convert the selected basic disk(s) to dynamic disk(s). If you convert the disk(s) to dynamic, you will not be able to start installed operation systems from any volume on the disk(s) (except the current boot volume). Are you sure you want to continue?"
I don't want to take this drastic step.
Is there a way for me to create a RAID 1 Volume with my two identical hard drives?

Can someone (Dell Support and/or Forum Member) answer this post. I also have the same setup and just bought a second drive to mirror my internal drive for protection from a hard drive loss but can't find information on how to setup the new drive to mirror my root drive. Any help will be much appreciated. Thanks!

In order to do this you're going to have to forego the cache drive -- make a set of recovery media for your system AND a backup of all the data you have on the sytsem, and then remove the mSATA cache drive and install the mirror drive. Enter setup and change to RAID mode and then restart, pressing CTRL-I when indicated to set up the mirrored pair of drives. Once that's done, boot the system from your recovery media and do a factory restore of the OS -- then reinstall your applications and restore the backup copy of your data files.
