3TB Secondary HDD in Dell Optiplex 755

[Go!pee]

Just bought a Western Digital Green 3TB from neighborhood store for the intention of use it as a secondary drive on dell Optiplex 755 Desktop. The trouble is that still through A19 BIOS (the most up to date) update the drive can merely be partitioned next to 2048 GB and the left over segment is out of stock. Are there whichever clues otherwise implications to obtain the complete quantity of space obtainable to the system? Specs:

• 4GB DDR2 5300
• 1TB Western Digital Green as Primary Drive
• Windows 7 64-bit

There are some renowned manufacturer of RAID controllers, the problem of disk> have 1 TB and 3 TB is completely out of the norm!. Anyone who has installed 3 TB drives and no UEFI Board who has a problem that he can only solve by changing the controller or by trickery. Where the Trixx should never ever used on a server, because these are very nasty Trixxs that doubt cannot be reproduced on another board - or to use degree one (s) which must reformat the disk if necessary.

This seems to be normal, at least I have ever heard of ner 2TB limit in Windows in general. You can even create an alternative Raid 5 array with 4 drives and can then still use the full space. Of course, you will then be displayed as the two drives in Windows, but this was supposed to be relatively unimportant, right?

The problem with XP is not the file system (NTFS supports up to 16 EiB) and not the operating system itself, but the size of the partition table. Can hold only 32-bit values for the number of sectors of the disk. Since the default size of a sector (not clusters!) Is usually 512 bytes, the maximum size of a disk is therefore limited to 2 TB. The sector size could be changed only with a true low-level format. How might this affect, I do not know. I have no hard drives are known which are shipped from the factory with a different sector size. The 2 TB limit can be overcome only with XP with stripe sets.

The first problem concerns the logical block addressing (LBA) hard disks, set by Microsoft and IBM thirty years ago. Designed for DOS, the standard LGB assigns an address to each 512-byte sector, limiting the maximum capacity of 2.1 terabytes. According to Seagate in 1980, nobody imagined that would have exceeded 2.1 TB.

For this reason, a 3 TB hard drives require an extension of the standard (Long LBA addressing), which increases the number of bytes used to define an address LBA. This new standard must be supported by the operating system. Among those currently on the market Seagate cites 7 and Windows Vista 64-bit and modified versions of Linux (there should be no problems with Mac OS). As for XP, the company said that in some internal tests the operating system has recognized only 990 MB of available 3 terabytes.

The BIOS is a problem, because the current master boot record partitions are locked to 2.1 TB. Need BIOS upgrade or switch to 'UEFI, the new environment initialization ready for hard drives 3 terabytes. The UEFI is currently only on some motherboards, so you can understand that switch to the new capacity is not nonsense but it requires the commitment of the entire industry.
