i've just got a new hd and have been re-purposing the older, internal 3.5"drives, which means erasing and renaming in disk utility. i've been able to erase the disks and rename/create new volumes. now, however, i'm stuck with the remaining drives and the following problem: each time i select the drive and erase/rename, a logical volume group is created. i've been able to erase the group in terminal, but each time i erase/rename in disk utility, a new lvg is created. has anyone seen this before? these drives are for media storage only. i don't need to roll my own fusion drive and just want to format and use the disks the "regular" way.
