will be less than that of the outer ring track. A sector is the smallest unit of data that can be read on a disk , a size of 512Bytes, which means that 1 bytes of files, regardless of whether the volume of data in this sector is 2KB or 16KB, is the size of a sector. The data inside each sector is treated as continuous data, so when you actually access it, you need to specify the address of the data in the sector to find the data you need.Four, the hard
When learning Linux, we often encounter some problems. Only by solving these problems can we better learn Linux. What is Linux hard disk partition? What is Linux hard disk partition used? Partition is the "section" of the
directory in the Linux storage space.Now let's look at how Red Hat Linux drives are identified. For IDE hard drives, the drive identifier is "hdx1", where "HD" indicates the type of device the partition is in, and this is the IDE hard d
Linux hard disk partition Basics
What are hard disk partitions and what are used for partitioning?
Partition is the "section" of the hard disk ". Windows partitions have their own drive letters (C:, D:, and so on), which look like an independent
In Windows, disk fragmentation is a common problem. If you do not pay attention to it, the system performance may be eroded. Linux uses the second extended File System (ext2), which processes file storage in a completely different way. Linux does not have the problem found in Windows systems, which makes many people think that disk fragmentation is not a problem at all. However, this is incorrect.
All file
written to the USB flash drive, not your first system on the disk (hard disk) above, that is, the MBR installed on your USB drive disk above, this is wrong, because the MBR is not a file, So you can't copy it from the USB stick to the disk on your first system. Because your u disk's MBR has been modified, so before the start of the U disk (U start) will not have
After learning about the Linux system, it was still quite smooth in general. For example, all the commands that can be typed in will get corresponding results .... But today, when I learned how to mount the Linux mount command, I was really depressed for a long time. It took about two hours. I found that no solution was found for various google and baidu instances... In the end, it was an unintentional tric
thought to write this, because I am in the process of tossing Linux system, there are many times to fall into the trap of the hard disk partition experience. In the last few days, once again fell into the pit, tossing two geniuses from the pit to crawl out. After a lot of inquiry data, finally understand the hard disk partition some concepts. Record it below to a

Note that for an IDE disk, the hard disk is displayed as sda after we start the boot system of the USB flash drive.
When using the Windows version of syslinux, be sure to use the-m option to ensure that the master startup record MBR of ISOLINUX is copied); otherwise, the original MBR will continue to be used, this will not point to your syslinux. cfg file.

Clear Disk
This method looks simple: Clear the disk drive, delete unnecessary files, and clear all files that need to be saved but will not be used. If possible, clear unnecessary directories and reduce the number of subdirectories. These suggestions seem obvious, but you will be surprised to find that ea
