Abstract

METHOD FOR COMPLETING A SECURE ERASE OPERATION A system that may reliably erase a storage device, such as a solid state drive. The 5 system issues an erasure command to the storage device. Such a command may be issued over a bus connecting a processing unit to one or more storage devices to be erased. The system, including the storage device, may be prepared for the erasure operation via performing one or more operations. Those operations may include: using hardware of the system to initiate a hard reset of the storage device; preventing access to the storage device 10 while the erasure operation is being performed; and/or erasing hidden areas on the storage device. The system may be configured to perform the hard reset and may be configured not to alter a command to perform secure erase. Further, the erasure process may include writing a signature to certain areas of the storage device to confirm that erasure was performed. 15 (FIG. 1)
