I'm guessing that's due to the fact that, according to what I've read, (from Wikipedia) "The organization of the partition table in the MBR limits the maximum addressable storage space of a disk to 2TB", and my disk is 3TB. According to what I've read, my disk should utilize GPT, but I'm not sure it is.
Anyway, I'll leave it at that. Glad I could help you figure out why Wisecare365 wasn't able to read the disk.
