Did you intend to discard the data on the disks when you formatted them (as that is the effect of a format). If the disks were being ‘emulated’ by using parity then as the disks were disabled the format operation would have done it to the ‘emulated’ drive, not the physical one.
the correct way to handle unmountable disks is covered here in the online documentation accessible via the ‘Manual’ link at the bottom of the unRaid GUI. Chances are that would have recovered any data on them.
once a disk is marked as disabled then the only way to clear that state is to rebuild the drive. If you want to do it on top of the current of themselves then that is documented here. It is quite possible, though, that the physical disks have their data intact if you want to try and recover it so you may not want to rush into the rebuild.
