I am attempting to split a
two-way mirror storage space. There are two physical disks in the storage space. The idea is to keep the contents of the storage space, while going back to NTFS. I do not have the additional disk capacity to copy over the contents of the storage somewhere else while I remove the storage space entirely.
Thus, I retired one of the two disks and attempted to format the retired disk. Unfortunately, when the disk is retired, it is still part of the storage space. I then attempted to repair the storage space, but it will complain there is not enough space and demands a HDD replacement to keep the two-way mirror intact. Since Windows does not seem to let me touch the HDD that's still in the storage space, I'm completely stuck at this point.
How can I force the HDD out of the storage space to format it as NTFS and copy the files over from the storage space? Or is there another way to accomplish my goal?
