correctly.Now is the time to create a disk drive storage pool. Because you need to identify the drive on your system. So the first time you run the LSBLK command to identify each drive.sudo lsblkNote the name of the block device, which should be ' SDA, SDB, SDC, 'Now we need to find the ID of each drive and we'll use it in the "pool" of the drive.sudo ls-l/dev/disk/by-id/This command will give you a long output. This is an example of my system (in my Ubuntu system, I have deleted the output of

1. Definition: run-time Type information (run-time type detection) refers to a program's ability to use a pointer or reference to a base class to examine the actual derived type of the object that the pointer or reference refers to. Two common types are available in the 2.c++ Rtti:typeID: returns the actual type of the object that the pointer or reference refers todynamic_cast: A pointer or reference to a base class type is safely converted to a pointer and reference of a derived type3.

If you have data on your hard disk, you must back up the data for your entire hard disk, not

Of course, manufacturers still have a duty to maximize the maintenance of high performance. Hardware manufacturers first in the solid state hard drive before the factory in advance of its total erasure (similar to the hard drive low-level format), the second is to prepare a dedicated space to store a dense burst of writing, enterprise-class hard disk will even retain up to 50% of the s

Right-click the My Computer icon on the Windows desktop and select the Properties System Properties window from the pop-up menu to appear. Click the Device Management tab. Double-click CDROM drive to view the hard drive list. Right-click the IDE disk (there may be other names, such as GENERIC IDE disk) and select Properties from the pop-up menu to appear in the Hard Disk Properties window. Click the Settings tab. Select DMA if the item is not selected, and then click Confirm. Windows asks i

The workaround is as follows: Need a system disk, first through the system disk to start the computer, and then hold down R key to perform repair installation system can solve the fault, of course, if the virus is caused, you can put the computer into DOS with anti-virus software to kill. If the hard drive fails, then run the cmd command on the Command Prompt window and o

Press F12 (different computer keys) to enter the BIOS setup project at boot time You want to make sure that your motherboard supports AHCI. If your motherboard supports AHCI, go to BIOS setup before installing Windows 7 and adjust the default IDE in SATA controller mode to AHCI in the advanced option. Turn on AHCI install Windows7 to make the system speed up to one times faster Attention matters AHCI, the full name of the serial ATA Advanc

the motherboard does not recognize the solution for the optical drive: 1. Plug the optical drive data line again or switch to a data line, change the location of the optical drive jumper, restart; 2.BIOS Verify that the IDE channel of the optical drive is not set to Disabled or closed; 3. Right click on "My Computer", select "Properties", in the pop-up window into the Device Manager page, and then click "Refresh" to see if the CD-ROM drive can be found; 4.
