FATX - Technical Design - Boot Sector
... floppy disks, the Boot Sector (VBR) is the first sector (logical sector 0 with physical CHS address 0/0/1 or LBA address 0)) ... For partitioned devices such as hard drives, the first sector is the Master Boot Record defining partitions, while the first sector of partitions formatted with an FAT file system is again the Boot Sector ... If the boot sector has a valid signature residing in the last two bytes of the boot sector (tested by most boot loaders residing in the System BIOS or the MBR) and this volume is booted ...
Sector Slipping - Example
... Logical Sectors Physical Sectors Pre Low-Level Format 7 ... Logical Sectors Physical Sectors Post Low-Level Format 0 -------> 1 ... -------> 2 ... -------> 2 ... The sectors were then slipped down to allow for the logical sectors to be placed in sequential order on good sectors ... Sector 3 was slipped down to 4 and sector 4 was slipped down to 6 ...
FATX - Historical Evolution - File System Types - Logical Sectored FAT
... the volume size limits imposed by the 16-bit sector entries and arithmetics by increasing the size of the sectors the file system dealt with, thereby blowing up dimensions ... These so called logical sectors were larger (up to 8192 bytes) than the physical sector size (still typically 512 bytes) as expected by the ROM-BIOS INT 13h or the disk drive hardware ... The DOS-BIOS or System BIOS would then combine multiple physical sectors into logical sectors for the file system to work with ...
FATX - Historical Evolution - File System Types - FAT12
... size was stored and calculated as a 16-bit count of sectors, which limited the size to 32 MB for a logical sector size of 512 bytes ... time was 5.25-inch (130 mm), single-sided, 40 tracks, with 8 sectors per track, resulting in a capacity of 160 KB for both the system areas and files ... The 32 MB limit was later circumvented using logical sectored FATs with logical sector sizes larger than 512 bytes in some OEM versions of MS-DOS 3.x, but this fell into disuse when FAT16B became ...

Famous quotes containing the word logical:

    Grammar is a tricky, inconsistent thing. Being the backbone of speech and writing, it should, we think, be eminently logical, make perfect sense, like the human skeleton. But, of course, the skeleton is arbitrary, too. Why twelve pairs of ribs rather than eleven or thirteen? Why thirty-two teeth? It has something to do with evolution and functionalism—but only sometimes, not always. So there are aspects of grammar that make good, logical sense, and others that do not.
    John Simon (b. 1925)
