Within the "Volume Space", the capacity that can be occupied by the content of files is also slightly reduced by file system overhead and by slack space as well, but the amount of slack space is trivial given that file systems on optical discs use a low cluster size (also referred to as "logical sector size") of 2 KiB (2048 bytes), matching the ...
MS-DOS/PC DOS versions 4.0 and earlier assign letters to all of the floppy drives before considering hard drives, so a system with four floppy drives would call the first hard drive E:. Starting with DOS 5.0, the system ensures that drive C: is always a hard disk, even if the system has more than two physical floppy drives.
A disk compression software utility increases the amount of information that can be stored on a hard disk drive of given size. Unlike a file compression utility, which compresses only specified files—and which requires the user to designate the files to be compressed—an on-the-fly disk compression utility works automatically through resident software without the user needing to be aware of ...
In the most common usage scenario, the user would have one hard drive in the computer, with all the space allocated to one partition (usually as drive C:). The software would compress the entire partition contents into one large file in the root directory. On booting the system, the driver would allocate this large file as drive C:, enabling ...
The first commercial digital disk storage device was the IBM 350 which shipped in 1956 as a part of the IBM 305 RAMAC computing system. The random-access , low-density storage of disks was developed to complement the already used sequential-access , high-density storage provided by tape drives using magnetic tape .
