CentOS users in the NTFS disk device read, found that such a format can not read the driver file, and mount failure, the main reason for this problem is that CentOS does not support the NTFS format, the following small set to CentOS 6.4 For example, to introduce the next CentOS 6.4 Cannot read the solution for NTFS disk devices. Problem: The dual system Win7 an

enough, with the df-h command to view the disk usage, found that/data partition only used 66%, and 12G of the remaining space, it is not supposed to appear this problem. Ii. Analysis of issues: Later, Df-i looked at the/data partition's index node (inode) and found that it was full (iused=100%), causing the system to create new directories and files. The inode translates into Chinese is the index node, each storage device (such as hard

The composition of a hard disk Hard disk We will not be unfamiliar, we can compare it to our computer to store data and information in a large warehouse. Generally speaking, no matter which kind of hard disk, it is composed of several parts, such as disc, head, spindle, control motor, head controller, data converter, interface, cache and so on. Figu

The second method tries to no

I swear, I will never buy Seagate hard disk again. Two 2 TB Seagate hard disks in a row cannot be read, and there are important backup data on them. One is that the computer does not fully recognize the data including the bios, and the other can recognize the data. One partition is raw and cannot be turned on. 650) This. width = 650; "src =" http://s3.51cto.com/

Use php to test the hard disk write speed. Copy the code as follows :? Phpset_time_limit (0); $ strstr_pad ($ str, 512,0); $ filefopen (. temp, a +); $ i0; $ bytes1000000000; $ mygabyte $ bytes1000000; E The code is as follows: Set_time_limit (0 );$ Str = str_pad ($ str, 512, "0 ");$ File = fopen ("./temp", "a + ");$ I = 0;$ Bytes = 1000000000;$ Mygabyte = $ bytes/1000000;Echo "test start. waiting ..."

05 the computer we purchased is still using the residual heat, but the system speed is surprisingly slow. The hard disk read/write speed detected today is less than 2 Mb/s, which is unacceptable. It is no wonder that the hard disk is set to Pio mode. Use the following methods to solve the problem: 1. Right-click my com

In CPU interpretation 1, we mentioned that one of the main functions of CPU is to control data interaction between devices. This naturally includes hard disks. All the data in the system is basically in the hard disk, so it is very important for the program to know how to read and write the

Use PHP to write a 1GB size file, check the hard drive write speed, there may be some error, It is recommended that you use a professional hard drive test tool to detect General computer reading and writing in 20m/s, this test t

Use the DD command in Linux to test the read/write speed of USB and SSD hard disks.Disk Drive Speed The disk drive speed is measured by the amount of read/write data per unit of time. T
