ABSTRACT:
A method of controlling a hybrid HDD to permanently deactivate a non-volatile cache support mode by determining whether a limit in the use of a non-volatile cache is passed, and a recording medium and apparatus suitable for the control method. The control method of a hybrid hard disk drive having a hard disk and a non-volatile cache includes determining whether an erasure number of the non-volatile cache exceeds a usage limit based on the erasure number of the non-volatile cache, and permanently deactivating a non-volatile cache support mode when the erasure number of the non-volatile cache is determined to exceed the usage limit.
