Hard drive and hard drive clone

A hard drive or hard disk is one of the main storage media in computing made of aluminium or vitreous discs. According to the working principle, hard drive can be divided into HDD (Hard Disk Drive), SSD (Solid State Drive), HHD (Hybrid Hard Disk). Among them, SSD is commonly used for system and HDD for data nowadays.

To clone a hard drive in Windows 7 means to copy all data completely from one hard disk to another through software or hardware. Generally, if you use software, it will write the contents of the whole hard drive into a backup file in case of restoration next time.
