A portable, cordless battery-powered tool with a relatively small overall length is provided. A handle section forms the rearmost part of the tool. An electric motor is located below a spindle and forwardly of the handle section. The motor has a rotatable shaft located in parallel with the spindle. The handle section is provided with a switch trigger which is substantially aligned with the central axis of the spindle at its top.

An accumulator wherein the peripheral speeds of separate, accumulating guide roller assemblies are caused by respective independent mechanical arrangements to coincide with the take-up speeds of first and second take-up devices. Using this arrangement, the speed of the optical fiber being accumulated is always equal to the peripheral speed of the accumulating guide rollers so that there is no instantaneous tension change that would otherwise result from a backlash of interconnecting gears.

In storage subsystems, due to the significant increase in HDD capacity, the time for executing online verification is elongated, affecting accesses from the host computer. By comprehending the status of accesses to the HDD, the sections where error has occurred and the status of restoration thereof, it becomes possible to detect defective or error sections efficiently at an early stage, according to which the reliability and access performance of the storage subsystem can be improved. The present storage subsystem executes one or more of the following processes: (M1) intensive verification of a circumference of an error LBA, (M2) an area-based prioritized verification, and (M3) continuous verification performed for a long period of time to (V1) an area in which error has occurred via IO access, (V2) a highly accessed area, and (V3) during a period of time when IO access is low.
