A method and apparatus are disclosed for isolating and attenuating shock and vibration in a disk module that includes media drives that are mounted on a printed circuit board (PCB). The apparatus includes a single printed circuit board (PCB), media drives that are coupled to the PCB, a first reinforcing rail that is attached to the PCB and to a first side of a first one of the media drives, a second reinforcing rail that is attached to the PCB and to a first side of a second one of the media drives, and a locking mechanism for locking the first and second rails together.

Media drive vibration isolation and attenuation method and apparatus

A circuit manages the conversion of data between a logical sector format and a physical sector format. In a padding mode, the circuit appends a padding value to a data stream in the logical sector format having a logical length to produce a data stream in a physical sector format having a physical length. In an extracting mode, the circuit extracts a data stream in the logical sector format from a data stream in the physical sector format.

Circuit for aligning logical sectors with physical sectors in a disk storage system

A software controlled system having a signal source connected to logic circuits via data busses. User operated circuitry permits any selected data bus to be temporarily isolated from the signal source so that maintenance and/or logic circuit replacement may be performed on the isolated data bus.
