Introduced in the fall, Seagate has now began shipping its 3TB Barracuda XT internal hard drive. The highest capacity hard drive is rare in supporting legacy operating systems such as Windows XP, which can't normally support hard drive capacities higher than 2.1TB. DiscWizard software that's available for download ships with the drive and lets the system read and write to, though not boot from, the extra-large drive.
