Striped volume over the boot drive

Hello,
I have two identical 500GB hard drives, one of which has Windows installed on it along with my programs and another is just a standard disk with other stuff on it (music, videos, etc...). I've been wanting to create a 50GB striped volume over both drives to benefit from faster writing, so I've created two 50GB volumes out of each hard drive respectively, as follows (C:\ is my boot drive with Windows on it):



However when I right click on the bottom-most unallocated volume, I cannot select Striped Volume (or anything else for that matter - only Simple Volume). And when I right click on the other volume, I can select Striped Volume but I cannot choose to add the other volume to the striped array.

Is there a problem here? I would've thought it would be possible to create a striped volume out of two unallocated volumes regardless of the hard drive they are on (provided they are on different hard drives which is the case here). Or am I missing something about basic/dynamic disks, etc...?

Thanks for your input everyone.

Anyone?

That.

RAID works on a whole-disk basis, you can't make part of a disk RAID and the other part not.

As the previous post says first convert the disks to dynamic, then you can add striped volumes.

Is there any risk or disadvantage to converting my disks to dynamic?

Basic and Dynamic Disks

dynamic has less compatabilty, even the windows 7 installer cant use dynamic disks.
If you only plan to use them in windows systems then it be fine.

However assuming you ok wiping the data on a windows reinstall should the day come you do need to reinstall win7 and the disk is still dynamic then there is a procedure using the repair tool command prompt of the install dvd to convert it back to basic so the installer can use it.
