LBA is a newer (for ATA it is newer) form of hard disk addressing which is a linear sector addressing scheme i.e., 0,1,2,3,4,5... as compared to CHS. LBA = (C * Number_of_Heads + H) * Sectors_per_Track) + S - 1 where C, H, and S are the CHS values of the desired address.
( ogical lock ddressing) - A method used with SCSI and IDE drives to translate the cylinder, head and sector specifications of the drive to those usable by an enhanced BIOS. LBA is used with drives that are larger than 528MB and causes the BIOS to translate the drives logical parameters to those usable by the system BIOS.
Logical Block Addressing. A mode used with hard drives that is 8.4 GB's. It is used instead of CHS addressing in most hard drives.
Logical block addressing is a technique that allows a computer to address a hard disk larger than 528 megabytes. A logical block address is a 28 binary digit value that maps to a specific cylinder head sector address on the disk.
A method of addressing the sectors on a drive. Addresses the sectors on the drive as a single group of logical block numbers instead of cylinder, head and sector addresses. It allows for accessing larger drives than is normally possible with CHS addressing.
Logical Block Addressing. A method of hard disk addressing that provides the ability to address hard disks up to 8.4GB. Part of the ATA-2 standard.
Logical Block Addressing, it is a translation method to allow your computer to support larger hard drives. Before you add a large hard drive (over 504 MB), be sure you have support for LBA translation in your system BIOS - the older BIOS don't support cylinders numbering above 1024. LBA does not use standard CHS parameters. For instance, if your drive has say 2000 cylinders and 16 sectors, LBA translation will make your software think your drive has 1000 cylinders, and 32 heads. Recent developments now allow drives as large as 8.4GB - soon to be broken again.
Logical block addressing. A method of accessing hard disk drives based on the extensions of INT 13.
A form of addressing used by Enhanced IDE to recognize hard drives over 528 MB, as specified in the original IDE standard. LBA literally translates the...
Logical Block Addressing (for enable SCANDISK.EXE) In BIOS setup - Hard Drive Auto Detect.
Stands for Logical Block Addressing, and allows the BIOS to remap a drive's geometry so drives larger than 504 MB to be configured. Requires BIOS support.
Logical Block Addressing Required by all IDE hard-disks larger than 528mb. Most newer Pentium systems use LBA permitting the use of IDE disks of any size up to 8.4 gigabyte. In older 286/386/486 systems LBA may be present in the BIOS or controller card. All IDE disk manufacturers provide software to overcome the 528mb limit.
Logical Block Addressing is the way that hard drives are accessed by the operating system, and is part of the BIOS.
Logical block addressing. A method used with SCSI and IDE disk drives to translate the cylinder, head, and sector specifications of the drive into addresses that can be used by an enhanced BIOS. LBA is used with drives that are larger than 528MB.
Logical Block Addressing. A new scheme for formatting hard disk drives that enables DOS to access drives larger than 528MB. Drives and controller cards that have this capability are called EIDE (Enhanced IDE) or Fast ATA.
ogical lock ddressing. A way to address IDE disks without Cylinder/Head/Sector (CHS) coordinates, using linear sector numbers from the start of the disk. Allows for the use of very large IDE disks.
Logical Block Addressing - A translation method used by BIOS of IBM PC compatibles to change the size limit of a hard disk drive from around 528MB to 8.4GB. The number of cylinders of a hard disk drive is decreased while the number of heads is proportionally increased, so that both parameters stay below their limits. The limits are 1024 for cylinders, 256 for heads and 64 for sector per track.
Logical Block Addressing. An Enhanced BIOS translation method that allows for larger hard drive sizes (up to 2 terabytes), by providing the Operating System with a long list of Logical Block Addresses instead of the Cylinder, Heads, Sector configuration.
