Were you using the server board RAID in any way (other than passthrough)? If not when you connect a single drive to another windows machine it should present as a normal NTFS disk with a hidden folder with that disk's Pool part in it,and whatever content was in that disk's part of the pool accordingly in there
Example: D:\PoolPart.37fd2833-0a62-42af-a2b7-f6899100db05
The premise of Drivepool is that it doesn't jiggy with the disks in any way,merely present a unified pool and manages file/folder placement in the background
*Edit to be more clear,you should be able to connect individual disks to a laptop/PC (I have a USB Dock for quick swaps) and read the pool disks individually even without drivepool
