file system is ZFS.Resolution process1. Hard Drive detectionBecause the storage is missing because some disks are out of line, the entire storage is not available. Therefore, after receiving the disk to do physical detection of all disks, after the detection of no physical failure. Then use the Bad Channel Detection t
I. BACKGROUND
Under the Ubuntu12 mounted hard disk (9TB) and Ubuntu12 under the reload hard disk article I have described the operation method of the mounted hard disk, then what is the difference? The physical hard disks in the last two articles were mounted directly on the server, but this time it was a
General our U disk (SD card), in My computer, the display is Removable Storage. We are here to change to---local disk, so that Windows to the U disk (SD card) recognized as a hard disk.
-----disk Drives in Device Manager-the list has a hard disk and your USB drive (SD card), right click to update the driver.

say, we think this article can bring more gains and shocks to readers. That's right! This article is not a simple article about knowledge popularization, but a disclosure of Hard Disk issues that are of common concern to users. Why is the hard disk vulnerable to damage? How does the manufacturer fix the hard drive? Ho
Buying a new hard drive solves the immediate storage space and can also help improve your computer system and rejuvenate your computer. However, before you transfer data from your old hard drive to your new hard
interface inside the plug-in is blue, it means that you can support USB3.0 transmission.
5. It is recommended that you choose USB3.0 Mobile Hard disk, of course, if the computer does not have USB3.0 blue interface, then even if the mobile hard drive is 3.0, will still automatically drop to USB2.0 transmission speed.
Do you need solid state drives
1. Solid-St
. In this way. The old hard disk can be converted into a mobile hard disk with a USB interface through the hard disk box.
There is also a kind of device called "easy drive" on the market. It is just a separate conversion port, which simply converts the interface of the original
The difference between SSD and ordinary hard drive
1. Solid State hard drive to start fast, no motor speed up the rotation process.
2. Solid state Drive without head, fast random read, read delay is very small. According to the relevant test: two computers in the same co
SAS hard Drive, is a serial connection to the next generation of SCSI technology, the use of serial technology to achieve higher transmission speed, and by shortening the connection line to improve the internal space. SAS is a parallel SCSI interface that develops a new interface. Improves storage system performance, availability, and scalability, and provides co
IDE's English is all called: Integrated Drive Electronics, is currently the most mainstream hard disk interface, including the main interface of optical storage class. It has become mature, cheap and stable after several years of development. The IDE interface uses a flat cable of 40 or 80 cores to connect the hard
More and more computers are equipped with dual hard disks. Generally, one of them is used as the system's primary disk, and the other is used as the storage disk. However, many users often hear that the hard disk is stopped and started. Why? In fact, this is the built-in hard drive
In today's computer system, the performance of the hard drive has become the biggest bottleneck affecting the performance of the machine. In the WINDOWS7 system with high requirements for accessories, the hard disk naturally becomes the object that needs to be optimized, and by turning on the AHCI mode of the hard
1. Hard drive Daily maintenance hard disk in the use of the process should pay attention to the following aspects:
Computer work is strictly forbidden to move or collision machine, otherwise it may make the hard disk head and disc collision, causing the hard disk head and d
The biggest difference between solid-state drives is storage media.
It's kind of like the physics of Junior high school. The propagation of sound in different media is not the same, and the speed of propagation in solids is higher than that in gas.Hard disk is also a reason AH, solid-state hard disk storage medium is flash chip, mechanical
Advantage 1. Start fast, no motor acceleration rotation process.
Advantage 2. Without the head, fast Random read, the reading delay is very small. According to the relevant test: two computers in the same configuration of the computer, the laptop with solid state drive from the boot to the desktop has taken a total of only 18 seconds, and the laptop with the traditional hard
What is a mixed hard drive:
Many friends of computer enthusiasts regard a hybrid hard drive as a solid state drive mixed with a common mechanical hard drive. In fact, mixed
extracting the boot area of the CD, but the operation is a little troublesome, so it is worthwhile to spend one or two minutes here.
Put the original installation CD of Windows XP into the optical drive, start ultraiso, press the "F5" key, or execute "Create a CD image file" in the "Tools" menu ", specify the storage location of an image file as prompted, and then the program will automatically start to re
After loading Ubuntu in VirtualBox, I found that the hard disk space is too small to increase the capacity of the hard disk. That is to build another hard drive:
1. Add a new hard drive
