硬盘无法初始化症状及解决办法（The hard disk cannot initialize symptoms and Solutions） The hard disk cannot initialize symptoms and Solutions 2006-8-11 10:47:56 -------------------------------------------------------------------------------- Hard disk initialization refers to the partition and formatting of the hard disk. In general, there are several kinds of hard disk drives that may cause initialization of the hard disk. (1) error in CMOS; (2) hard disk infection virus; (3) logic lock in hard disk. In the first case relatively easy to handle, generally as long as the CMOS will be set to default values can be solved, the user can BIOS FEATURES SETUP in VIRUS WARNNING is Disable view CMOS settings, if it is not correct to try. If the CMOS setting is complete, the user can perform second steps, i.e., checking the virus, if the disk cannot be initialized. The virus may cause the hard disk partition table to be destroyed, thus unable to complete the hard disk formatting work. In the third case, the logical lock of the hard disk cannot be initialized, and the user can break it through the two methods described below. Before we begin to introduce a specific implementation, lets look at the logic lock principle. The computer will search all the logical order in DOS system, when DOS is booted, partition table first to go looking for the boot sector, the first sector in a fraction of the hard disk cylinder 0 OBEH address of the place to start, when the partition information began to place for 80H that is the main boot partition, other the extended partition, the main boot partition is defined as a logical disk drive, and then look for the extended logic disk partition, is defined as a D disk, and so on to find E, F, G... This is the logic of lock. To modify the first logical disk normal main guide to the extended partition partition record myself, when DOS starts to find the first logical disk, find the next logical disk always find themselves, thus the formation of a cycle of death, this
