HDD partitioning scheme when installing UbuntuHttp://www.cnblogs.com/shenliang123/p/3196743.htmlIf you are going to install only one Ubuntu operating system on your hard drive, it is recommended that you adopt a three-partition scheme: "/", "swap", and "/home"./: 10GB-15GB.Swap: Physical memory is less than or equal to 512MB, it is recommended to allocate the actual physical memory capacity of twice times the size of swap, physical memory is greater t

function to make the brief explanation, thus we can understand, to the hard disk's very large part work, by the hard disk controller can complete. And for floppy disk, its controller is much simpler, we need to program to complete various functions, so the floppy disk driver becomes more complex. Here we only discuss the hard drive driver. 2. Implementation of HDD driver in Linux The driver that we're going to talk about in Drivers/ide/hd.c, in the f

Hard disk cloning, which is a disk clone, is used to copy all the data from one disk to another, and its purpose is embodied in the following areas: HDD Upgrade: Upgrade your old hard drive or small hard drive to a new large hard drive, and use disk cloning to upgrade your hard drive to avoid reloading the system and reinstalling the application. Migrate data: Quickly migrate all data from one disk to another disk. Making a backup disk: All data on

The SuperFetch Super Pre-read service is also ineffective for game programs, for individual users and gamers, opening this service will only be intangible loss of CPU performance time, loss of disk IO addressing the threading performance.

step to fix at this point-"Select Entry Mode" (Set capacity pattern). In this interface must choose the "(C) ylinders" (stigma) option, enter the input after entering the capacity of the interface. In this interface, the capacity is entered according to the cylinder surface. For the first partition (that is, C-disk), are starting from the 1th cylinder, but now we have to change the front of the "0" to "1", as for the end of the partition is not necessary to modify the number of cylinders, can b

　How to see mobile hdd old and new First look at the calculation to see how many bytes your hard drive shows on your computer, use it with 1024 to see if there is 30G; second, look at the hard disk's label and serial number, there are no traces of sanding; three is to copy a large file to try, listen to the hard disk when reading data when there is no noise. A good hard drive has no noise, and the old hard drive will squeak. Secondly, we can use the

There are two ways to mount a hard disk on a Linux system:1, MOUNT/DEV/SDB1 (hard disk location)/HOME/TEMP1 (Mount position)2, NTFS-3G/DEV/SDB1 (hard disk location)/HOME/TEMP1 (Mount position)If the hard disk location cannot be determined at this time, you can view the disk partition using the following command line:1, Cat/proc/partitions2, disk load time and other details: Ll/dev/disk/by-pathUse the following command to read the contents of the drive:Ll/home/temp1Linux Mount

Tags: start lin device file logical IDE Linux named logical partition COLA: Linux system hard disk naming is file-based, generally:/dev/hda2 and/dev/sdb3#/dev: is the directory where all device files are stored. #hd和sd: They are the first two letters of the partition and represent the type of device on which the partition resides.
