Seagate has joined the ranks of hard drive manufacturers producing 3TB hard drives for consumers. The 3TB Barracuda XT has 64MB of cache, a 6Gb/s SATA connector, and platters spinning at 7,200rpm. In order to create partitions larger than 2.1TB, it’s necessary to have all of the following: a 64-bit post-Windows XP OS, a UEFI bootloader, and a machine capable of GPT partitions. Most people don’t have all of those yet, so Seagate is making available its DiscWizard soft ware, which will help legacy users create multiple partitions to use all available space—no hardware addon necessary.
