Abstract
A data storage device includes a computer-readable medium encoded with a computer program that, when executed communicates with a basic input/output system (BIOS), receives a user selection from the BIOS to wipe the data storage device and performs a wipe of the data storage device. In an embodiment, the wipe of the data storage device includes writing a series of 1s and/or 0s to substantially all data bits of the data storage device.
Claims20
A computer-readable medium encoded with a computer program that, when executed:
- receives a user selection through a basic input/output system (BIOS) to wipe a data storage device having a plurality of existing data bits;
- performs a wipe of the data storage device, wherein the wipe of the data storage device includes overwriting an initial portion of the plurality of existing data bits of the data storage device until a power interrupt occurs;
- and
- upon a subsequent power up, determines that a flag has not been cleared and, in response, either restarts the wipe of the data storage device to overwrite the plurality of existing data bits of the data storage device or continues the wipe of the data storage device to overwrite a remaining portion of the plurality of data bits of the data storage device.
An information handling system (IHS) comprising:
- a processor;
- memory coupled with the processor;
- and
- a data storage device coupled with the processor and having a plurality of existing data bits;
- and
- a computer-readable medium encoded with a computer program that, when executed:
- receives a user selection through a basic input/output system (BIOS) to wipe the data storage device;
- performs a wipe of the data storage device, wherein the wipe of the data storage device includes overwriting an initial portion of the plurality of existing data bits of the data storage device until a power interrupt occurs;
- and
- upon a subsequent power up, determines that a flag has not been cleared and, in response, either restarts the wipe of the data storage device to overwrite the plurality of existing data bits of the data storage device or continues the wipe of the data storage device to overwrite a remaining portion of the plurality of data bits of the data storage device.
A method of wiping a data storage device, the method comprising:
- providing an information handling system (IHS) including a data storage device having a plurality of existing data bits, and including a basic input/output system (BIOS) to control startup of the IHS;
- receiving a user selection through the BIOS to wipe the data storage device;
- performing a wipe of the data storage device, wherein the wipe of the data storage device includes overwriting an initial portion of the plurality of existing data bits of the data storage device until a power interrupt occurs;
- and
- upon a subsequent power up, determining that a flag has not been cleared and, in response, either restarting the wipe of the data storage device to overwrite the plurality of existing data bits of the data storage device or continuing the wipe of the data storage device to overwrite a remaining portion of the plurality of data bits of the data storage device.
