In a block-based storage environment, a single block of information is addressed using a LUN identifier and an offset within that LUN known as a logical block addressing ( LBA ).
After all, consider Logical block addressing and Block ( data storage ) . ( Although as 512e shows, LBAs and presented sector sizes don't have to correspond to physical sector sizes.
They were among the first to support Logical Block Addressing ( LBA ) and Self-Monitoring, Analysis, and Reporting Technology ( S . M . A . R . T . ) monitoring.
In addition, until Windows XP with Service Pack 1, Windows was unable to handle hard drives that are over 137 GB in size with the default drivers, because of missing 48-bit Logical Block Addressing support.
In 1996, support for logical block addressing ( LBA ) was introduced in Windows 95B and DOS 7.10 in order to support disks larger than 8 GB . " Disk timestamps " were also introduced.
CompactFlash IDE mode defines an interface that is smaller than, but electrically identical to, the C-H-S and 28-bit logical block addressing ( CF 5.0 introduced support for LBA-48 ).
In C H S addressing the " sector " numbers always start at "'1 "', there is no " sector 0 ", which can lead to confusion since logical sector addressing schemes ( e . g ., with Logical block addressing ( LBA ), or with " relative sector addressing " in DOS ) typically start counting with 0.
These include a fix to improve dual-layer support, one to implement a non-aligned data buffer ( which allows " Gradius V " to be played from the HD ), one to defeat newer copy-protection measures ( popularly known as the " God of War " fix ), one to support the new " slimline " SCPH-70000 series PlayStation 2 hardware and one to implement 48-bit Logical Block Addressing ( which allows HD Loader to take full advantage of hard drives larger than 137 GB; or 128 GiB, as reported by HD Loader ) as of 0.7c hard drives of up to 2 Terabytes can be used.
