Mixtape

A mixtape (also mix-tape or mix tape) is a home-made compilation of music (typically copyrighted songs taken from other sources) recorded in a specific order, traditionally onto an audio cassette, though CD or MP3 playlist formats are now more common. The songs can be sequential, or by beatmatching the songs and creating overlaps and fades between the end of one song and the beginning of another the tape may become a seamless whole. Compilations may include a selection of favourite songs, or music linked by theme or mood, perhaps tailored to the tape's intended recipient.

Essayist Geoffrey O'Brien has called the personal mix tape "the most widely practised American art form".

History

Host protected area

The host protected area (also referred to as hidden protected area) is an area of a hard drive that is not normally visible to an operating system (OS).

History

HPA was first introduced in the ATA-4 standard cxv (T13, 2001).

How it works

The IDE controller has registers that contain data that can be queried using ATA commands. The data returned gives information about the drive attached to the controller. There are three ATA commands involved in creating and using a hidden protected area. The commands are:

Operating systems use the IDENTIFY DEVICE command to find out the addressable space of a hard drive. The IDENTIFY DEVICE command queries a particular register on the IDE controller to establish the size of a drive.

This register however can be changed using the SET MAX ADDRESS ATA command. If the value in the register is set to less than the actual hard drive size then effectively a host protected area is created. It is protected because the OS will work with only the value in the register that is returned by the IDENTIFY DEVICE command and thus will normally be unable to address the parts of the drive that lie within the HPA.
