5, if the failure is still, it is recommended to reload the operating system.
Second, set the CMOS parameters
For a friend who has never used a USB add-in, it is possible that the system cannot detect a USB hard drive even if the driver is properly installed, mainly because the default CMOS port on the motherboard is turned off, and if it is not set to open, Then Windows naturally
moved by the HDD is USB to direct power, in some cases, due to insufficient power to the USB interface caused by the inability to read and cause hard disk damage. Recently, almost all of the mobile hard drives come with a separate external power supply or a PS2 adapter that takes power from the keyboard , and some uses a dual USB interface to power it. Therefore
