A mass storage device using an optical disk such as a compact disk, DVD-RW, BLU-RAY disk or the like to mimic to the operating system and BIOS of a electronic device the operations of a traditional magnetic fixed media device (hard drive). The invention teaches that an optical disk may be provided with sectors and tracks, a sealed case, a boot sector, "hard disk" information to provide to the BIOS and OS, track access control of servomechanisms, a repeatable run-out error constant, and other "hard drive" features. An OS interface module mimics to the OS the operations of the hard drive while an interface to optical disk control translates between the hard drive type commands and the actual optical disk controls. Optical disk controller and subcomponents and the disk itself may be modified from usual optical disk layout and mechanisms to better mimic fixed magnetic media operations.
