Portable storage device that can check memory free space

摘要

A portable storage device is provided with a memory part, a free space detecting part, a vibration detecting part, a reporting part, and a controller. The memory part stores data. The free space detecting part detects a free space of the memory part. The vibration detecting part detects vibration. The reporting part reports the free space. The controller performs writing and reading of data for the memory part. If vibration is detected by the vibration detecting part, the controller causes the reporting part to report corresponding to the detection result of the free space of the memory part by the free space detecting part.
