lot of track lengths. After the introduction of the multi-zone recording technology, the peripheral tracks can be divided into more sectors, thus increasing capacity. The above is the physical structure of the hard disk, the hard disk is just storage media, let us plan the storage of the data on the hard disk, this is the

Installing a Linux system on a computer, partitioning the hard disk is a very important step, and here are a few of the partitioning schemes.Scenario 1/: Recommended size is above 5GB.Swap: Swap partition, the recommended size is one or more times of physical memory.Scenario 2/boot: Used to store the Linux system boot-related programs, such as boot loader, etc.,

second logical partition is represented as "Hda6"File partition types for two Linux(1) EXT4:4th-Generation Extended file system for storing data partitions for files and directories RHEL6 the file system by default(2): Swap: Swap file system for the Linux system to establish a swap partition, which acts as virtual memory, the swap partition can not be used to directly store the user's files and directories and other data.You need to provide a root (/) partition and a swap partition when install

GIMP2.4.2 and DiskManager are visualized hard disk partitioning tools-general Linux technology-Linux technology and application information. The following is a detailed description. Image Processing Software GIMP released version 2.4.2 today. GIMP 2.4.2 is an updated version for the 2.4 stable branch. It does not add any new features and only fixes various bugs. GIMP 2.4.2 mainly removed corrupted and inval

partition. This is the biggest difference between primary and extended partitions and logical partitions. This is the best example when we specify the bootloader for Linux installation and boot on the primary partition. Linux requires that the primary partition (or extended partition) occupies the first four numbers from 1 to 16. Taking the first IDE hard disk as an example, the primary partition (or extended partition) occupies hda1, hda2, hda3, and

[Reference] General Algorithm for calculating hard drive integer partitions (from computer reports): partition size = (partition size-1) × 4 + 1024 × partition size If you calculate the X-1 according to the hard disk partition integer G formula) * 4 + 1024 * X = Y where X is the value of the integer partition you want, in the unit of G, Y is the number you should enter when

Partition of a removable hard disk, if the disk is bad and other failures, is it beneficial to protect the data? That is, E disk produces bad way, will not affect the F disk. Or, in the immediate absence of partition, is also bad way of the region data anomaly, and no bad road area is normal, and whether the partition is irrelevant? Answer: Hard disk partitioning
