KryoFlux reads "flux transitions" from floppy disks at a very fine resolution. [6] It can also read disks originally written with different bit cell widths and drive speeds, with a normal fixed-speed drive. [7] The software is available for Microsoft Windows, [8] Mac OS and Linux. The KryoFlux controller plugs into a standard USB port, and ...
A bit nibbler, or nibbler, is a computer software program designed to copy data from a floppy disk one bit at a time. It functions at a very low level directly interacting with the disk drive hardware to override a copy protection scheme that the floppy disk's data may be stored in. In most cases the nibbler software still analyses the data on ...
On other systems, like the Apple II and Atari 8-bit computers, almost all software is self-booting. On the IBM PC, the distinction is between a self-booting program and one which is started by the user via an operating system such as MS-DOS or IBM PC DOS. The term "PC booter" was not contemporaneous with when self-booting games were being released.
SpinRite is claimed by its developer to have certain unique features, [4] such as disabling of disk write caching, disabling of auto-relocation, compatibility with disk compression, identification of the "data-to-flux-reversal encoder-decoder" used in a drive, and separate testing of buffered and unbuffered disk read performance, and direct ...
8-inch floppy disk, inserted in drive, (3½-inch floppy diskette, in front, shown for scale) 3½-inch, high-density floppy diskettes with adhesive labels affixed The first commercial floppy disks, developed in the late 1960s, were 8 inches (203.2 mm) in diameter; [4] [5] they became commercially available in 1971 as a component of IBM products and both drives and disks were then sold ...
The best-known floppy disk drive for the C64, the 1541 is a single-sided 170-kilobyte drive for 5¼" disks. The 1541 directly followed the Commodore 1540 (meant for the VIC-20). The disk drive uses group coded recording (GCR) and contains a MOS Technology 6502 microprocessor, doubling as a disk controller and on-board disk operating system ...
With special software it's possible to read C1581 disks on an x86 PC system, and likewise, read MS-DOS and other formats of disks in the C1581 (using Big Blue Reader), provided that the PC or other floppy handles the "720 kB" size format. [5] This capability was most frequently used to read MS-DOS disks.
The Commodore 1571 is Commodore's high-end 5¼" floppy disk drive, announced in the summer of 1985. With its double-sided drive mechanism, it has the ability to use double-sided, double-density (DS/DD) floppy disks, storing a total of 360 kB per floppy. It also implemented a "burst mode" that improved transfer speeds, helping address the very ...
