Seagate has announced a 3 TB hard drive
Seagate Technology has promised to launch production of the world's first 3TB HDD by the end of the year.
In developing the drive, a number of new technologies were used, thanks to which, on the one hand, a recording density that was fantastic for mass production, but on the other hand, some users will have problems.
The fact is that most modern operating systems support only the LBA standard - the addressing mechanism and access to the data block on the hard drive, where the system controller does not need to take into account the geometry of the hard disk itself (number of cylinders, sides, sectors per cylinder). LBA was developed back in the 80s of the last century and addresses data by sectors, each of which consists of 512 bytes. The volume of the hard drive partition with the standard LBA can not exceed 2.1 TB.

The Seagate three-byte drive will be built on the basis of a new addressing mechanism - Long LBA. 64-bit versions of Win 7 and Win Vista will be able to work with it, but Win XP users will have problems - the system will still determine the hard drive as 2.1-terabyte.
Bypassing this trouble in Seagate is going with the help of special software that will be supplied with the hard drive and will allow users of outdated OS to split the disk into several sections, each of which will be less than 2.1 TB.
The delivery time and estimated cost of the new hard drive in Seagate is not called, but it can be assumed that the model will be on sale for the New Year holidays.
