<p>Salvaging event trace information in power loss interruption (PLI) scenarios, for use in solid-state drive (SSD) and hard disk drive (HDD) storage devices. If volatile state information that is salvaged after an inadvertent power loss were to include event trace information, then such information can provide a valuable debug resource. Event trace information from volatile memory is copied to a second memory upon a power on which is in response to a PLI event. A corrupt state of context reconstruction data stored on non-volatile memory is detected, and an indication of the corrupt state is set. The event trace information is passed to the host if requested based on the indication.</p> |
