Test hard drive Bad Sectors in CentOS
Hard Disk status testing tools: smartctl, Badblocks, hdparm
You can quickly see whether the hard disk is healthy by using smartctl. The command is as follows:
[Root @ qy ~] # Yum installsmartmontools-y
Start SMART
# Smartctl -- smart = on -- offlineauto = on -- saveauto = on/dev/sda
[Root @ qy ~] # Smartctl-a/dev/sda

Finally, a self-owned server is assembled. The configuration is as follows:

Total fee: 1500 + 2050 + 1170 + 1720 + 1450 = 7890 RMB
I wanted to build it into Xeon, but I bought this chassis very early on. The CPU fan is blown from the right. It is not suitable for general Xeon boa
another ). PCI bus is a more advanced bus structure. Its functions are much better than those of other bus. It can be used to support the sticky-ysh of the delayed-ring hybrid column bed? 32 Mbps, one of the fastest data transmission bus, supports multiple groups of peripheral devices at the same time. PCI is not subject to CPU processors, and is compatible with various existing buses. The size of the Main Board slots is small, so the cost is low, which is conducive to promotion.

Your Mac's memory is usually not very large, plus a time machine backup using your Mac, which requires an external USB flash drive or hard drive. U disk storage space is small, we will not go to partition, directly to use on the Mac or Windows on it. So this is just about hard drives. Now the USB interface of the mobile HDD cabbage price, four hundred or five hundred dollars 1 T hard disk is now the most commonly used, but also I buy the type. I hope this drive can be used on a time machine back

Mobile hard drive believe that everyone will not be unfamiliar, similar to ordinary hard disk, only the mobile hard disk emphasis is portable mass storage products, so the mobile hard drive more than the use of USB or IEEE1394 faster interface, can be higher speed and system for data transmission. It can be said that the mobile hard disk, disk and other Flash product upgrades, is widely accepted by the general public, then the mobile hard disk is currently the main brands and brand ranking situa

that large and the speed is not so fast; however, in actual use, the hard disks in many other aspects are better than the current hard disks. For example, the noise is very small, and you even need to stick your ears on the disk to hear the sound of Hard Disk rotation. The service life is long. A friend of mine has an original IBM 486DX33 computer, the MB hard disk in it is still in normal use, no noise, no bad channels, the seek time can still reach the nominal value, the performance has not b

Now most people have been accustomed to buy online accessories, but there will be not at ease, such as the purchase of hard disk will ask the author how to query the authenticity, in fact, check the authenticity of the hard drive is very simple, only need to login official website, simple one-step input serial number can be.
First, let's look at the west number of hard drive authenticity Query method.

SATA II is the chip giant Intel Intel and HDD giant Seagate Seagate developed on the basis of SATA, its main feature is that the external transmission rate from the SATA 150mb/s further increased to 300mb/s, in addition to the NCQ (Native Command Queuing, native command queue, Port multiplier, staggered start (staggered spin-up) and a series of technical features. Pure external transmission rate of 3Gbps is
The 3D gaming performance of entry-level computers is limited, AMD and Intel's set contrast is 50-step laugh 100 Steps, so this level of configuration more value computing power and stability. To be comprehensive, the entry-level configuration is a good choice based on the Intel-proven Pentium G620 processor and the H61 motherboard. In addition APU highly integrated configuration is also a good choice. Today, the editor first recommended a 2800-yuan upgrade for easy entry configuration, details
