摘要： A disk drive is disclosed which executes a rotational position optimization (RPO) algorithm for selecting a next command to execute out of a plurality of pending commands. The RPO algorithm comprises a first phase and a second phase. The first phase of the RPO algorithm is executed relative to a first priority and in response to at least one non-real-time parameter. The second phase of the RPO algorithm is executed relative to a second priority higher than the first priority and in response to at least one real-time parameter.

摘要： A mass storage system made of flash electrically erasable and programmable read only memory ("EEPROM") cells organized into blocks, the blocks in turn being grouped into memory banks, is managed to even out the numbers of erase and rewrite cycles experienced by the memory banks in order to extend the service lifetime of the memory system. Since this type of memory cell becomes unusable after a finite number of erase and rewrite cycles, although in the tens of thousands of cycles, uneven use of the memory banks is avoided so that the entire memory does not become inoperative because one of its banks has reached its end of life while others of the banks are little used. Relative use of the memory banks is monitored and, in response to detection of uneven use, have their physical addresses periodically swapped for each other in order to even out their use over the lifetime of the memory.

摘要： A disk drive is disclosed comprising a disk having a plurality of tracks, and a head actuated over the disk. Control circuitry heats the head in order to reduce a fly-height of the head, and computes a target servo sector to begin a preheat period. The control circuitry decreases the heat so that the fly-height is increased during at least part of a seek operation to seek the head from a first track to a second track. When the head reaches the target servo sector, the control circuitry increases the heat to decrease the fly-height during the preheat period.

摘要： A disk drive is disclosed which links disk commands that access near sequential data sectors. The linked and non-linked disk commands are inserted into an input/output queue and selected for execution according to a rotational position optimization (RPO) algorithm. If an error occurs while executing a linked disk command, the disk commands are unlinked and at least one of the unlinked disk commands is executed. The residual unlinked disk commands are inserted back into the input/output queue for later execution in an order determined by the RPO algorithm.

摘要： A disk drive is disclosed wherein if a write command is aborted, the write command is re-executed according to a rotational position optimization (RPO) algorithm rather than immediately re-executing the write command to better optimize drive performance relative to mechanical latencies. An aborted write command is replaced into an input/output queue together with other pending commands. The aborted write command is eventually re-selected for execution by the RPO algorithm when executing the write command minimizes mechanical latencies relative to the other pending commands.

摘要： Controlling a buffered data transfer between a source and a destination by loading a source count value and a destination count value from a buffered data transfer device. A source delta value is computed by subtracting a source previous value from the source count value. The destination count value is adjusted on the buffered data transfer device by adding the source delta value to the destination count value. A destination delta value is computed by subtracting a destination previous value from the destination count value. The source count value is adjusted on the buffered data transfer device by adding the destination delta value to the source count value. A new value for the source previous value is computed by adding the source count value and the destination delta value. A new value for the destination previous value is computed by adding the destination count value and the source delta value.
