2.1 Handling Microdrives Microdrives are used in GZ-MC100 and GZ-MC200. Although the appearance is different, a Microdrive is exactly the same as a hard disc that is used in a PC. Therefore, unlike handling conventional tapes, caution must be paid in handling Microdrives. The handling of Microdrives is explained in this section. 2.1.1 The structure of Microdrives The detailed inside structure of Microdrives is not disclosed as it is treated as trade secrets. However, it is essential to have knowledge of the structure of Microdrives in order to carry out service properly. Some information about Microdrives is given here.

2.1.6 About DDD CF II compliant 1-inch small hard disk (Microdrive) is used as recording media of this model. For operation check and maintenance of this Microdrive, drive fitness test software: Drive Diagnostics &Disposition (DDD) is provided from Hitachi Global Storage Technologies (HGST) with a license agreement. HGST supplies the Microdrive's parts to JVC. Double click this program. The handling of this software is explained as follows. Notice This software is developed to confirm, analyze, and restore the various kinds of hard disks. However, JVC is allowed to use DDD software only to test, confirm, and restore the Microdrive to the factory setting. (2) Press Next button to proceed the installation. Thus, the use of other functions is prohibited. Using software other than DDD may damage the installed hard disk of the PC or may disable the reading of the stored data. Please understand that we do not at all compensate any damage caused by the usage other than instructed, and that we cannot accept any inquiry. If you have any questions or requests, please do not contact HGST that is displayed when installing the software, but do contact Camcorder CS Group, AV & Multimedia Company. 2.1.6.1 Platform Requirements Press Next button DDD operation requires the following platform requirements. Al- though it may operate on lower specification platforms, we do not guarantee the operation under such platforms.
