A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
A basic data partition can be formatted with any file system, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 file systems. To programmatically determine which file system a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record .
For FAT32 file systems, the reserved sectors include a File System Information Sector at logical sector 1 and a Backup Boot Sector at logical sector 6. While many other vendors have continued to utilize a single-sector setup (logical sector 0 only) for the bootstrap loader, Microsoft's boot sector code has grown to span over logical sectors 0 ...
Media can be played from any device connected to the console i.e. external USB/FireWire/thumb drive/hard disk drive (FAT32 only), the internal hard disk on early revision consoles, optical CD-R(W)/DVD±R(W) discs (modded systems or patched discs), or network shares (Windows Network or PS2 host: protocol). A number of homebrew emulators of older ...
File Allocation Table (FAT) is a file system developed for personal computers and was the default file system for the MS-DOS and Windows 9x operating systems. [citation needed] Originally developed in 1977 for use on floppy disks, it was adapted for use on hard disks and other devices.

All models support USB memory devices; flash drives and external hard drives are both automatically recognized. However, they must be formatted with the FAT32 file system. [27] Earlier systems supported up to four USB 2.0 ports at the front (20 and 60 GB models, as well as the NTSC 80 GB), but the 40 GB and 80 GB PAL models only have two USB ...
The protective MBR is stored at LBA 0, and the GPT header is in LBA 1, with a backup GPT header stored at the final LBA. The GPT header has a pointer to the partition table (Partition Entry Array), which is typically at LBA 2. Each entry on the partition table has a size of 128 bytes.
