Exclusive: Seagate confirms 3TB drive

“After a few weeks of rumours, Seagate’s senior product manager
Barbara Craig has confirmed to Thinq that “we are announcing a 3TB
drive later this year,” but the move to 3TB of storage space
apparently involves a lot more work than simply upping the areal
density.

“The ancient foundations of the PC’s three-decade legacy has
once again reared its DOS-era head, revealing that many of today’s
PCs are simply incapable of coping with hard drives that have a
larger capacity than 2.1TB.

“The root of the problem is the original LBA (logical block
addressing) standard, which can’t assign addresses to capacities in
excess of 2.1TB. Originally set out by Microsoft and IBM as a part
of the original DOS standard, the original LBA standard assigns an
address to each 512-byte sector – the smallest physical block
of data on a hard drive”
