Today a 1T capacity of the mobile HDD suddenly turned RAW, before this mobile hard drive has C:, D:, E: Three hard disk partitions, the first C: partition is 200G size, the second is 500G size. When the hard disk has a RAW phenomenon, do not do anything else with the disk first. Here's how to resolve RAW using Diskgenius: 1, connected with the problem of the mobile hard disk, the desktop Select the "Computer" click the right mouse button, select t

Exit and reopen the application Many other applications, such as Safari Explorer, Chrome Browser, Photoshop, and so on, create a lot of temporary cache files at run time. If you have not exited these applications for a long time, these cached files will continue to grow and generally will not be purged (until the application is exited). Of course you can also delete the cached fi

In the context of the current global energy shortage, energy conservation is one of the most important issues we face in the future. In the field of lighting, LED lighting products are attracting the eyes of the world, led products as a new type of green light source products, not only high light efficiency, and energy-saving environmental protection, stability, safety and reliability, will inevitably becom

This chapter will complete a real Linux drive. The Linux driver is used to control 4 LEDs on the Development Board. That is, by sending data to the Linux driver, you can control the switch of the LED light.First, the realization and principle of LED driveAlthough the Linux driver deals directly with hardware, it is not the Linux driver that writes data directly to the memory in the hardware, but interacts w
