HP will begin shipping Advanced Format Hard disk drives (4K) for 3.5-inch drives in all Business PCs, Workstations, and Point of Sale Systems by the end of the first quarter of the 2012 calendar year. This is due to the supply shortages resulting from flooding in Thailand.
Advanced Format technology uses 4K byte sector boundaries for physical data storage on the hard drive, but will continue to communicate logically to the system in 512 byte sectors. These 512 byte logical sectors are known as 512 byte emulation or 512e and are necessary to maintain compatibility with current and legacy operating systems.
note:During the transition, Business PCs, Workstation, and Point of Sale Systems will ship with either Advanced Format hard drives or 512n hard drives until the supply of 512n drives is depleted. Spare Parts will ship either Advanced Format hard drives or 512n hard drives until the supply of 512n drives are depleted.SKU numbers for the systems will remain the same regardless of the hard drive technology used in the configuration.
