HDD should automatically work with Snow Leopard
A Seagate representative has provided Electronista with a few additional details regarding Mac compatibility for the upcoming 3TB Constellation hard drive. In-house testing reportedly showed 3TB of usable space on Snow Leopard, indicating that Mac users should be able to utilize the full capacity of the drive without any special configurations or software updates.
Installation on Macs should be easier than many Windows 7 PCs, as Macs already utilize the necessary EFI firmware rather than using a BIOS. Certain older systems might only be able to recognize smaller volumes such as 2.1TB or 1TB of capacity without long logical block addressing (long LBA).
The 3TB drive is expected to be released sometime later in the year, although Seagate has yet to provide specific details regarding launch dates or pricing.
