That will work perfect. I will just run that in a command prompt and read it
out one by one and remove the dynamic disks from my array.
Thanks!

Hi,.
Dyanamic disks are partitioned using Logical Disk Manager (LDM)
partitioning. The LDM subsystem in Windows, which consists of user-mode and
device driver components, oversees dynamic disks. LDM maintains one unified
database that stores partitioning information for all the dynamic disks on
a system--including multipartition-volume configuration.
As far as I know, there're no API for calling LDM service.
The LDM database resides in a 1-MB reserved space at the end of each
dynamic disk. Unfortunately this database's format is not officially
documented.
Sysinternals.com has a freeware called ldmdump.exe
(http://www.sysinternals.com/Utilities/LdmDump.html) which can display the
database content.
For a basic disk, the output will be:
Logical Disk Manager Configuration Dump v1.03

Disk does not have LDM database.
For a dynamic disk, the output will be:

So as a workaround, you may use this tool to output the information and
check for string "Disk does not have LDM database" to determine whether or
not this is a basic disk.
Please reply to let me know whether or not you need further information.
Thanks.
