First, the hard diskThe function of a hard disk is quite simple but important, and it is responsible for recording the various data required by the system. The hard disk record data has two aspects, one is the hardware aspect storage principle and the structure, on the other hand is the software aspect data and the file system. The main behavior of a hard
C ++ hardware information to obtain the hard disk serial number and the hard disk serial number This section describes how to obtain the serial number of a hard disk, not the serial number of a hard disk partition. The core is throughDeviceIoControlInterface to obtain the ve

program in Linux, and viewing the source will find that the command is to send some IOCTL commands to the disk. But notice that since you can get it, you can set it, so be careful when using this command. Of course, we just want to get a view of the hard disk information, so there is no damage to the hard disk and system. Typically, the-I or-I (uppercase i) opti
|--------------------------------------------------------------Although the use of Linux fedora distribution for more than a year, but in fact, there are many details of the knowledge is not careful to think about, such as hardware devices in the Linux/dev directory under some naming rules.First look at the hard drives that we touch the most:now the mainstream hard disk according to the interface can be ca
In software encryption protection technology, a common protection method is license authorization based on hardware fingerprint. This article will introduce the specific hardware fingerprint acquisition technology in detail and provide a demo source code program. Hardware fingerprint encryption means that after a user obtains and installs the software for free,
U disk appears big and small problem, many times we can through some measures and software to solve, but if there is a hardware failure, many people do not know how to deal with, hardware failures generally appear in the poor quality U disk, because the main board of the U disk

How did you pull the USB stick after you used the U disk? is not a lot of people are directly pulled out, and then put away the next time to use it? The consequences of this do not think there may be damage to the file, or directly to the damage to the U disk, in fact, is very possible. Small knitting today to teach you a way, let this practice become formalized. In fact, U

Obtain the hardware information of the machine (cpu id serial number, motherboard information, hard disk serial number, and system information: 41 keywords: hardware CPU motherboard hard drive font: [large, medium, small] In many cases, you may need to obtain the hardware information of the microcomputer. For example,
One day, an office computer needs to re-install the operating system. After the system is installed, the computer is started. Unlike the normal Windows Startup interface, the system prompts "due to disk hardware problems of the computer, windows cannot start and cannot read the selected boot disk. Check the boot path and disk
How to view cpu, memory, hard disk, and other hardware information in linux Note: in Linux, you can view detailed information about each cpu in/proc/cpuinfo. However, for dual-core CPUs, two CPUs are displayed in cpuinfo. It is often mistaken for two single-core CPUs.

In many cases, you may need to obtain the hardware information of the microcomputer. For example, you want to lock your software and prevent others from accessing it at will. The most effective way is to get the serial number of the CPU, and then let your software run on a machine with such a serial number. As we all know, the CPU serial number is unique! Therefore, you can lock your software. Another example that requires hard
