-The '''[[Atari 810]]''' was a [[floppy disk]] drive for the Atari 400 and 800 computers, using a 5 1/4" single-density soft-sector disk format consisting of 720 sectors (numbered from 1 to 720 decimal, or 1 to 2D0 hex) each containing 128 bytes (numbered from 0 to 127 decimal, or 0 to 7F hex). This resulted in a total capacity of 90 kilobytes. The sectors were arranged in 40 tracks of 18 sectors each. Data was stored with [[FM encoding]].

 The contents of the disk were organized using the [[Atari File Management Subsystem]] (FMS) as the filesystem. This allocated sector 360 (168 hex) for the VTOC (Volume Table of Contents) and sectors 361-368 (169-170 hex) for the directory. Sector 720 (2D0 hex) was unused (due to it not being addressable by the file system because of a conflict in its zero-based numbering from 0 to 719 being unable to address it, while it can address a nonexistent zero sector), and bootable disks had the boot record in sector 1 (followed by a DOS.SYS file in the next few sectors), leaving the remaining sectors free for user files.
