Seagate Confirms 3TB Hard Drive

Stoobalou writes "After a few weeks of rumours, Seagate's senior product manager Barbara Craig has confirmed that the company is 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."

      Um, no. The sector size dictates what boundaries the OS has to do reads and writes on. It doesn't dictate how the OS uses the space. 4k sectors means that to read or write an aligned 4k filesystem block, the OS has to do one I/O operation instead of eight; and that if it wants to write a 512-byte block, it has to do a read-modify-write cycle.

      How efficiently small files get stored is a property of the filesystem, which doesn't even know about the sector size. Common filesystems all use 4k blocks or bigger anyway. Some filesystems store files smaller than 4k efficiently by packing them in with the metadata or dedicating some blocks to store several files per block. Filesystems that do this include, most notably, NTFS, and also some Linux filesystems like ReiserFS and btrfs. Wikipedia calls this block suballocation (don't know if this term is standard). This is totally orthogonal to the sector size.

      The Bios doesn't know anything about partitioning. It only knows it needs to read sector 0 of a disk into memory at 0x7c00 and jump to it. If the disk is MBR partitioned that's the MBR and the code there knows how to scan the partition table, and load the boot sector of the partition table using INT 13h. If it's not partitioned sector 0 is the boot sector of the partition table already and will use INT 13h to load the OS boot loader.

      GPT is different because sector 0 contains a "Protective MBR" that just reserves the whole disk. That doesn't contain any code - EFI Bioses need to read boot code from a special FAT formatted partition (Macs apparently use HFS+ instead). EFI Bioses offer a much more complicated API than the Bios, which is good in some ways (flexibility) and bad in others (more chance of bugs).

      But non partitioned disks have always been supported. In fact floppy disks are always non partitioned.

      Actually it's a shame that sector 0 of an GPT disk doesn't contain code to load a boot manager that understands GPT to allow booting from a GPT disk with an old fashioned Bios. Or that some way for old style Bioses to boot from disks with a partition table with 64 bit LBAs in wasn't developed - MBR partitioning only has space for 32 bit LBAs.

Now it's cheap to build home recording studios, or even engage in amateur independent movie production with only a few hundred dollars' worth of equipment, running free software.

      It's amazing, and with storage capacity growth increasing (not decreasing) we'll find new ways to fill up the storage media, very likely doing things we haven't anticipated even today.

    You need to be able to use larger than 32-bit block addresses. This is possible since the LBA spec uses 48-bit addresses. But the internals of some OSes use only 32-bit block addresses. The solution to this is to use a 64-bit OS. That allows 48-bit addresses (and then some).

    Another other problem is that the MBR disk partitioning scheme uses 32-bit block addresses, so you can't partition a disk larger than 2TB. But the answer to this is to use GUID disk partitioning.

    Finally there's your BIOS, it probably only supports MBR and 32-bit LBA. GUID disk partitioning supports making your disk look like an MBR disk so you can boot off it. You'll have to boot off a partition that starts within the first 2TB of the disk, but other than that you should be okay. Just make sure to never use any tools that think your disk is an MBR disk when you are repartitioning it or otherwise accessing it directly.

    Windows 7 (or Vista) 64-bit supports >32-bit LBA and GUID disk partitioning.
