Various embodiments of the invention use a non-volatile (NV) memory to store hiberfile data before entering a hibernate state, and retrieve the data upon resume from hibernation. Unlike conventional systems, the reserve space in the NV memory (i.e., the erased blocks available to be used while in the run-time mode) may be used to store hiberfile data. Further, a write-through cache policy may be used to assure that all of the hiberfile data saved in cache will also be stored on the disk drive during the hibernation, so that if the cache and the disk drive are separated during hibernation, the full correct hiberfile data will still be available for a resume operation.
