ATAPI ( ATA Packet Interface) is a protocol used with the Parallel ATA (IDE) and Serial ATA standards so that a greater variety of devices can be connected to a computer than with the ATA command set alone. It carries SCSI commands and responses through the ATA interface. ATAPI devices include CD-ROM and DVD-ROM drives, tape drives, magneto ...
Parallel ATA. Parallel ATA ( PATA ), originally AT Attachment, also known as Integrated Drive Electronics ( IDE ), is a standard interface designed for IBM PC -compatible computers. It was first developed by Western Digital and Compaq in 1986 for compatible hard drives and CD or DVD drives. The connection is used for storage devices such as ...
It was originally written to support SCSI devices; support for ATAPI devices was added later. Most other SCSI host adapter vendors (for example BusLogic, DPT, AMI, Future Domain, DTC) shipped their own ASPI managers with their hardware. [3] Adaptec also developed generic SCSI disk and CD-ROM drivers for DOS (ASPICD.SYS and ASPIDISK.SYS).
Optical discs. SCSI Multimedia Commands ( MMC) defines a SCSI / ATAPI based command set for accessing and controlling devices of type 05h. Such devices read or write optical media: CD, DVD, BD. T10 subcommittee is responsible for developing MMC as well as other SCSI command set standards. It was approved in December 1997 by ANSI.
Hard disk drive interface. Hard disk drives are accessed over one of a number of bus types, including parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Bridge circuitry is sometimes used to connect hard disk drives to buses with ...
The Apple Partition Map maps out all space used (including the map) and unused (free space) on disk, unlike the minimal x86 master boot record that only accounts for used non-map partitions. This means that every block on the disk (with the exception of the first block, Block 0) belongs to a partition.
Since 1983. Small Computer System Interface ( SCSI, / ˈskʌzi / SKUZ-ee) [ 2] is a set of standards for physically connecting and transferring data between computers and peripheral devices, best known for its use with storage devices such as hard disk drives. SCSI was introduced in the 1980s and has seen widespread use on servers and high-end ...
The CD-ROM itself may contain "weak" sectors to make copying the disc more difficult, and additional data that may be difficult or impossible to copy to a CD-R or disc image, but which the software checks for each time it is run to ensure an original disc and not an unauthorized copy is present in the computer's CD-ROM drive.
