I have four USB external HDDs on a PC running as a server. Two 320GB HDDs, and two 250GB HDDs. I would like to span a 320GB with a 250GB to create one logical volume, and do the same with the other two drives, to have two (approximately) 570GB partitions, one for storage and one for backup. If the problem is that external drives cannot be converted to dynamic, is there any way to trick Windows? Also, if there is a way to convert them, and one drive gets removed, when it is reconnected will Windows remount the volume?
Thanks for the help.
