Drawings from IBM Floppy Disk Drive Patents. IBM's decision in the late 1960s to use semiconductor memory as the writeable control store for future systems and control units created a requirement for an inexpensive and reliable read only device and associated medium to store and ship the control store's microprogram and at system power on to load the microprogram into the control store.
A disk operating system (DOS) is a computer operating system that resides on and can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc.A disk operating system provides a file system for organizing, reading, and writing files on the storage disk, and a means for loading and running programs stored on that disk.
In 2008, Hard Disk Sentinel DOS version was released in different formats on bootable pen drive, CD, floppy. Usable when no operating system installed (or if the system is not bootable otherwise) to detect and display temperature, health status of IDE, SATA hard disk drives and with limited AHCI controller support.
