Abstract
An information handling system (IHS) is provided that permits continued recording of a medium when a planned power loss occurs while the medium is being recorded in a media drive. If a low power condition is encountered during recording, the IHS saves location information regarding a last written block prior to the planned power loss. When power is restored, recording resumes at a location related to the location information.
Claims15
An information handling system (IHS) comprising:
- a processor;
- a memory coupled to the processor;
- a media drive, coupled to the processor, that records information to a medium therein;
- and
- a non-volatile storage, coupled to the processor, for storing instructions that when executed by the processor cause:
- writing, by the media drive, data on the medium;
- detecting a low power condition;
- saving data progress information;
- obtaining resume writing information including one of a logical block address (LBA) and a last physical sector number (PSN);
- storing the resume writing information in the nonvolatile storage;
- powering down the IHS in response to detecting the low power condition;
- and
- in response to detecting restoration of power to the IHS, resuming writing at a location determined from the resume writing information.
A method of operating an information handling system (IHS) including a media drive, the method comprising:
- writing, by the media drive, data on a medium in the media drive;
- detecting a low power condition;
- saving data progress information;
- obtaining resume writing information including one of a logical block address (LBA) and a last physical sector number (PSN);
- storing the resume writing information on a nonvolatile storage in the IHS;
- powering down the IHS in response to detecting the low power condition;
- and
- detecting when power is restored to the IHS and in response resuming writing at a location determined from the resume writing information.
A portable information handling system (IHS) comprising:
- a processor;
- a media drive, coupled to the processor, that records information to a medium therein;
- and
- a non-volatile storage, coupled to the processor, for storing instructions that when executed by the processor cause:
- writing, by the media drive, data on the medium;
- detecting a low power condition;
- saving data progress information;
- obtaining resume writing information including one of a logical block address (LBA) and a last physical sector number (PSN);
- storing the resume writing information in the nonvolatile storage;
- powering down the IHS in response to detecting the low power condition;
- and
- in response to detecting restoration of power to the IHS, resuming writing at a location determined from the resume writing information.
