2. Description of Related Art

Nowadays, it is a multimedia information era, in which the desktop computer and the portable computer have become important tools which are indispensable in people's lives. The main difference between the portable computer and the conventional desktop computer is that the portable computer is required to be lighter weight, thinner, and smaller, so that it can be easily carried by the user, and to provide the user with the usage convenience during operations on the computer under various environments. To meet user demands for a portable computer which is lighter weight, thinner, and smaller, many portable computers do not have a built-in optical disc drive (ODD). Meanwhile, a portable computer can only have one hard disk drive (HDD) built inside, while a desktop computer can be equipped with several hard disk drives at a given time for meeting the needs for data storage.

Since many portable computer users still have the need for using ODD and external HDD, the external ODD and the external HDD have been developed accordingly. However, the additional external ODD and HDD to be carried shall bring much inconvenience to users and also departure from the trend of lighter weight, thinner and smaller units. Moreover, many users have a desktop computer and a portable computer at the same time, in which the inconvenience of backing up and exchanging of the data between the two computers increases the complexity during use.
