Abstract
A data deleting method for a computer storage device is implemented by first setting a default status of a delete-able status for a deletion record file in the storage device when the storage device is powered on, where the default status can be enable or disable. If the delete-able status of the deletion record file is kept in an enable state before the storage device is powered off, the whole data stored in the storage device is deleted automatically when the storage device is powered on next time. This is because the enable state of the delete-able status of the deletion record file is detected by a control unit of the storage device. Therefore, the method can prevent the data in the storage device from any theft or unauthorized usage.
