This read-only integer identifies the physical media type of the printer's installed long-term storage device, reporting eHhardDisk when a hard disk is present or eHother for a different media type, and it is a fixed, unchanging value for whichever device is installed. Because it returns a noSuchName error rather than a value when no mass storage device is present, this object doubles as a simple way to detect whether the printer even has a disk installed. For instance, a monitoring script that gets noSuchName on hrdiskstoragemedia would know not to bother polling hrdiskstoragecapacity either, since there is no disk to report on.
