Reloading the system, the second hard disk is gone, and the solution is

. Re-doing the system from three points and doing it at 8:30 is a tragedy. In order to completely liberate the C drive, it is no longer the tragedy of the C drive space.

The original 160G main disk is not partitioned and all used to make the C drive results need to be formatted. . . And it is the formatting when the system is not running. . . In order to find a hard disk full of people to borrow a broken ghost disk, first put the hard disk full and then directly Ghost an XP restart. . . The hard drive is gone! ! ! ! ! ! Open my computer. Look, there is only one solitary C drive? ! ! ! ! Open Device Manager Two hard drives clearly hang here Open Disk Manager Repository Disk becomes protected hard disk free space 0 Random search all kinds of sayings What hard disk is broken Partition table error What IDC device is disabled What Drive letter error and so on and so on. . . Because it is still necessary to change back to win7sp1 [This time the purpose of doing the system is to re-do Win7sp1]
