Description

  The present invention relates to a storage device destruction device and a storage device destruction method for destroying the storage function of various storage devices mounted on a computer, for example, a hard disk drive.

  Computers are provided with various storage devices represented by hard disk drives.

However, the hard disk drive may be able to recover the data that should have been deleted simply by erasing the stored data with software. As a method for preventing data from being reliably read, there is a method for physically destroying the hard disk drive.

  The destruction device of Patent Document 1 destroys a hard disk drive by pressing the hard disk drive with a pressing head and a cradle. In addition, the destruction device disclosed in Patent Document 2 destroys a hard disk drive by forming through holes in a plurality of locations of the hard disk drive.
