I believe that you mean to ask if hard disk drives are considered volatile storage media or not. Volatile memory is memory that is lost when the storage medium is not being supplied with electricity. Hard drives do not need power for storage, only for reading and writing data from and to the platters; this means that hard drives are not volatile storage media.
There are many different options for data storage. You can use zip drive, external hard drives, or even online storage for your data needs.
