hard disk cannot detected

Linux systems do not automatically recognize and load new devices like Windows systems, requiring manual identification and manual loading. Everything in Linux is file. The file is organized by a large file tree, and the root directory of the file tree is:/, progressively expanded from the root. These documents are spread through a number of equipment. The command mount (Mount) connects the file tree in the device to the file tree on the Linux system, which means that the new device can be loade

Common sense: Hard Disk Bad Track classification-different bad track points carefully Because hard disks use magnetic media to store data, some problems will inevitably occur after a long period of use or improper use, that is, what we usually call "Bad channels ", of course, this type of bad track may be a software error, or a hardware fault on the

I saw an introduction today. How the hard disk works and the cause of damage, and finally how to set the system to reduce frequency Read/write damage to the hard disk. Address: http://blog.csdn.net/uiiang/archive/2004/10/19/143302.aspx I feel really professional and knowledgeable. Different responses. Be sure to rememb

detected, the partition is the active partition, and the first sector of the active partition (operating system boot record area, Dos boot RECORDER,DBR) is read into the memory address 0000:7c00h. Check if the 0000:7DFEH-0000:7DFFH (DBR's end flag bit) is equal to aa55h, and if not equal then show: "Missing Operating System" and then stop. When a partition is detected to satis

I. Hard DiskComposition Hard drives are no stranger to everyone. We can compare them to our computers.A large warehouse that stores data and information. Generally, either hard disk is composed of disk, Head, disk spindle, control

Not long ago, my old computer's hard drive broke down and there was a lot of information in it, so it was very depressing. I wanted to recover the hard disk data and asked about the price. I was shocked and decided to learn more about the hard disk restoration technology. Yo

software and pctools tools such as software can be carried out, but also can be found in those who are not yet found by the existing anti-virus software virus. Because the virus spreads fast, new viruses are emerging, and there is no common program to detect all viruses, or through code analysis, you can determine whether a program contains virus detection procedures, so only by comparison and analysis, or combination of these two methods to discover new viruses. Check the main boot area of th

. t. detected, that is, S. m.A. r. t. only 60% of the test results are correct, so we cannot fully rely on S. m.A. r. t. monitoring results. At present, all hard disks on the market have S. m.A. r. t. (Self-Monitoring, Analysis and Reporting Technology), smartmontools is a software package that uses this feature to monitor hard disks, including smartctl and smart

First, we need to understand how some hard disks partition related concepts. Please read the following nouns to explain: Physical Disk: The real hard disk we call "Physical Disk", English is called "PhysicalDisk". Logical Disk: "C

Hard Disk Bad Track soft Repair Method Bad hard drive channels (especially physical channels) are the most troublesome of all hard drive failures. If it is light, your machine will frequently crash, and the heavy data will make all your data useless. In the past, we generally only used low-level or hidden methods. Howe

analysis of the difference between U disk and mobile hard disk First, the principle of storage is different. U disk is a semiconductor material (chip) as a storage unit, also known as solid memory, there is no mechanical part. The removable hard

The former is a conservative setting, and the performance of the entire system slows down,However, if the user's system is unstable, You can fine-tune it based on this setting; the latter is the default BIOS factory settings, if the user has modified a lotIf it is not appropriate to set the parameters, you can use this item to restore th
