I've just bought three brand new 3TB drives which I've inserted into my JBOD ("just a bunch of disks") 4-bay removable Firewire 800 enclosure (Proavio S4) and for some reason they show up with only 746.5GB after formatting them! I've tried reformatting and partitioning to no avail. The 3 drives are 2x Western Digital WD30EZRX and 1x Seagate Barracuda ST3000DM001. They all show the same drive sizes so it's reasonable to assume the drives aren't at fault, so I'm wondering if the drive enclosure has some issues. Unfortunately I have no way of testing out the drives with anything else at the moment. I've been using Western Digital 2TB drives (WD20EARS) without any problems in the same enclosure. Am I missing something or is this likely a problem with the enclosure?
