Course Introduction：Bad sectors cannot be really fixed, but can be isolated or marked by tools to protect data. 1. Use the built-in chkdsk command of Windows to scan and mark bad sectors to avoid the system from continuing to write data; 2. Use third-party software such as CrystalDiskInfo, HDTune, Victoria to conduct in-depth detection and processing; 3. After discovering bad sectors, data should be backed up and replaced with the hard disk, because bad sectors are often a precursor to hard disk aging and the stability is difficult to recover.

Course Introduction：When a hard drive has a bad channel, you should first confirm the type and deal with it in time. The detection methods include scanning and repairing using the built-in chkdsk tool in Windows, or in-depth detection of health status through third-party software such as CrystalDiskInfo and HDTune; in terms of processing methods, logical bad channels can be repaired by system tools, and physical bad channels need to be marked and skipped. It is recommended to back up data, avoid continuing to use, and consider replacing the hard disk. If it is an external device and the bad channels continue to increase, you can try low-level formatting but be careful to operate.

Course Introduction：Whether your hard drive is healthy can be detected by system tools and third-party software. 1. Use Windows' chkdsk to scan and fix errors and bad channels, but only basic detection is required; 2. Check SMART data (such as CrystalDiskInfo or DiskUtility) to understand the power-on time, temperature and error records. If the status prompts abnormality, you need to prepare for a disk change; 3. Use third-party tools such as HDTune or Victoria to perform in-depth stress tests, pay attention to avoid misuse of write mode; 4. If the operation slows down, frequent lags or abnormal noises occur in daily life, it may be a precursor to hard disk failure, and the data should be backed up immediately.

Course Introduction：The specific reasons for this phenomenon may be relatively complex, including user usage habits, confusion of hard disk partition table information, hard disk hardware failure, motherboard abnormalities, and system-level problems. For this type of problem, whether or not we can clearly identify the cause, we recommend that we first timely backup important data to other storage devices (such as USB drives, mobile hard drives or burning CDs). After ensuring data security, you can try to check whether there are physical bad channels in the hard disk, and you can consider repartitioning and formatting the hard disk before reinstalling the operating system. Required tools: HDTune download version: Freetrial (free trial version) Download the free trial version of HDTun from the official website, and after the installation is completed, open the HDTun on the desktop

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
