An exercise bench includes a seat and a back which are independently adjustable angularly and are mounted on a carriage that rolls along rails of a stationary base. The linear position of the bench can be adjusted without the need to move any part of the frame along the surface on which the base rests. The adjustments for the angular positions of the seat and base and for the linear position are easily accessible and operable by a user sitting on the seat. The seat has an independent angular adjustment but can be maintained locked to the back so that pivotal adjustment of the back to different inclinations does not affect the angular position of the seat relative to the back.

The method of claim 4, wherein the devices are disk drives in a serial storage architecture (SSA) system. 6. The method according to claim 4 further comprising the step of: providing a switch and a control circuit coupled to the communication lines for controlling and switching the system between the normal operation mode and the glitch mode. 7. The method according to claim 6 wherein the providing step further comprises the step of: providing a quad-pole, double throw switch having four switch devices with four respective switch components. 8. The method according to claim 7 wherein the step of providing a quad-pole, double throw switch further comprises the steps of: using a first one of the four switch devices to switchingly couple the positive transmit communication line from the one of the at least two devices to the positive receive communication line to the another of the at least two devices when the system is in the normal operation mode and to switchingly couple the positive transmit communication line from the one of the at least two devices to the negative receive communication line to the another of the at least two devices when the system is in the glitch mode, using a second one of the four switch devices to switchingly couple the negative transmit communication line from the one of the at least two devices to the negative receive communication line to the another of the at least two devices when the system is in the normal operation mode and to switchingly couple the negative transmit communication line from the one of the at least two devices to the positive receive communication line to the another of t
