On April 5, 1999, Amir Ban, Dov Moran, and Oron Ogdan of M-Systems, an Israeli company, filed a patent application entitled "Architecture for a Universal Serial Bus-Based PC Flash Disk". [ 11 ] [ 3 ] The patent was subsequently granted on November 14, 2000, and these individuals have often been recognized as the inventors of the USB flash drive ...
To set up a live USB system for commodity PC hardware, the following steps must be taken: A USB flash drive needs to be connected to the system, and be detected by it; One or more partitions may need to be created on the USB flash drive; The "bootable" flag must be set on the primary partition on the USB flash drive
PC DOS 1.x file attributes included a hidden bit and system bit, with the remaining six bits undefined. At this time, DOS did not support sub-directories, but typically there were only a few dozen files on a diskette. The PC XT was the first PC with an IBM-supplied hard drive, and PC DOS 2.0 supported that hard drive with FAT12 (FAT ID 0xF8 ...
The first magnetic tape drive, the Univac Uniservo, recorded at the density of 128 bit/in on a half-inch magnetic tape, resulting in the areal density of 256 bit/in 2. [6] In 2015, IBM and Fujifilm claimed a new record for the magnetic tape areal density of 123 Gbit/in 2 , [ 7 ] while LTO-6 , the highest-density production tape shipping in 2015 ...
A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. [1] [2]Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space.
Whereas NOR flash might address memory by page then word, NAND flash might address it by page, word and bit. Bit-level addressing suits bit-serial applications (such as hard disk emulation), which access only one bit at a time. Execute-in-place applications, on the other hand, require every bit in a word to be accessed simultaneously. This ...
Because file size references are stored in eight instead of four bytes, the file size limit has increased to 16 exabytes (EB) (2 64 − 1 bytes, or about 10 19 bytes, which is otherwise limited by a maximum volume size of 128 PB, [nb 2] or 2 57 − 1 bytes), raised from 4 GB (2 32 − 1 bytes) in a standard FAT32 file system. [1]
It bypassed MS-DOS and directly accessed the disk, either via the BIOS or (preferably) 32-bit disk access (Windows-native protected mode disk drivers). This feature was a backport from the then-unreleased Windows 95, as suggested by Microsoft's advertisements for Windows for Workgroups 3.11 ("the 32-bit file system from our Chicago project").
