Data Storage Device and Method for Bypassing a Read-Only Mode to Allow User Data Backup

A method comprising:

• performing in a host in communication with a data storage device comprising a memory, wherein the data storage device is operating in a read-only mode which prevents the host from writing information in the memory of the data storage device that is needed for the host to boot the data storage device, wherein the information comprises a time stamp of the boot and a status of the boot:
• sending a disable read-only mode command to the data storage device to temporarily bypass the read-only mode;
• sending a write command to the data storage device to write the information in the memory needed for the host to boot the data storage device;
• backing-up the data stored in the memory of the data storage device;
• and
• after the data has been backed up, sending a restore read-only mode command to the data storage device;
• and
• powering off the data storage device.

A data storage device comprising:

• a memory;
• and
• means for:
• receiving a disable read-only mode command from a host to bypass a read-only mode of the data storage device which prevents the host from writing information in the memory needed for the host to boot the data storage device, wherein the information comprises a time stamp of the boot and a status of the boot;
• in response to receiving the disable read-only mode command, bypassing the read-only mode to allow the host to write the information in the memory needed for the host to boot the data storage device;
• receiving commands from the host to back-up data stored in the memory;
• after the host finishes backing up the data stored in the memory. receiving a restore read-only mode command from the host prior to powering down;
• and
• re-entering read-only mode.
