I have a 2nd HDD connected to my PC. This HDD has only one Extended partition with a Free space and 3 Logical drives in it.
When I right click on Free space and try to create a New Simple Volume with all the defaults it gives me an error: "There is not enough space available on the disk(s) to complete this operation."
How can I create Logical drive(s) on the Free space?
