As the most important storage device of a microcomputer, hard disks play an important role in the microcomputer system. If the hard disk cannot be started, it will cause you to be in a hurry. Here we will introduce you to several "weapons" to specifically deal with the "stubborn" problem that hard disk cannot be started. You must be careful when using them. Other
installation methods, you must first learn the "partition" method and then install again!

■ The partition cannot be opened, and the message "This partition is not formatted" is displayed"
Fault: When a drive letter cannot be opened during normal use, the system prompts "This partition is not formatted"
There is no doubt that direct re-formatting can solve the problem, so if there is no important file information in this partition, xiaobian strongly recommends that you directly format
