to promote their own professional software, it can repair the Physical Bad Sectors of the hard disk and does not affect the hard disk capacity, resulting in a daily price of more than 10 thousand yuan. Especially when Russia's PC-3000 entered China, this information was even more eye-catching.

First, capacity
The current market on the mobile hard disk capacity from dozens of G to a few T (1g=1000g), the class is multifarious, the price from sell his grove b
hard Disk Interface
The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all

Add:
Solid-state hard disk and mechanical hard drive to distinguish between many, first of all, from the shape, the mechanical hard disk is larger than the solid state hard disk,
between a magnetic hard disk and a solid-state hard drive (ssd:solid state disk).
It is important to note that both the hybrid hard drive and the solid-state drive use flash memory to improve read and write performance, but the
Mobile hard disk in the use of sometimes problems, such as data loss in the mobile hard disk, mobile hard disk virus and so on, and even some users because the use of incorrect methods, causing problems in the hard disk is possible. In fact, when using the mobile hard disk a

The numbering format of Western data varies by product family, and the numbering method is simple and clear, consisting of 12 numbers or letters. In 12 numbers, the first 6 numbers are the primary number, and the next 6 numbers are additional numbers. The main series o

Using 40GB system partition, 24GB game partition. Such partitioning scheme can be very effective to improve the performance of the system, at the same time 24GB game zoning can be installed in any super large 3D games, loading speed is very ideal. The following is a set of comparison of the scene loading wait time in "Island Crisis 2".

With a network card, you can, but the speed is still not too fast, and if the two computers are not connected with the network card, or several kilometers apart. Then the extraction box will be able to play a role, as long as in advance in some often handcuffed to the computer insta

Similarly, if the user upgrades to select a single IDE design motherboard, then the original three IDE devices must give up one, and in the "dual hard drive single optical channel drive" Such configuration, is often abandoned is that small hard
With the price of SSD solid-state hard drives down, later assembled computers to use SSD solid-state hard drive will become mainstream, at present, SSD solid-state hard disk capacity is small, and the price than mechanical
One, SSD (solid State hard disk) is what side sacred
SSD is mainly divided into the following two categories:
SSD based on Flash: Flash chips are used as storage media, which is what we usually call SSDs. Its appearance can be made into a variety of touch samples, such as: Notebook hard disk, micro-hard disk, memory card, USB flash
Understanding SCSI Hard drives:
Every time the SCSI disk is released with a new specification, the SCSI drive then supports the new specification, making the SCSI hard drive a leader in SCSI peripherals. Since the development of hard disk technology has been quite mature, s

"Cool disk for the server's I/O (input and output capabilities) and the stability of the disk requirements are relatively high." At the beginning of the procurement server, we chose a variety of servers, and even tried to DIY server according to the type of business. But we found that Dell servers were easy to pass in the same-tier, same-price
the interface of the mobile hard disk data transmission rate, that is, the external transmission rate. The speed of the external transmission rate depends on the interface type of the product. (See Second interface type)
Four, size
At present, the common mobile hard disk size is 3.5-inch, 2.5-inch, 1.8-inch three kinds. One of the 3.5-inch mobile hard
practical applications, it is also customary to use the IDE to address the earliest IDE type hard disk ATA-1, a type of interface that has been eliminated with the development of interface technology and later branched out into more types of hard disk interfaces, such as ATA, Ultra ATA, Interfaces such as DMA, Ultra DMA, and so on are part of the IDE hard disk.
the processing method of moving the hard disk into water:
The mobile hard drive that just soaks water is unable to receive electricity.
Now can only wait for the cold dry to try, if not, you have to change the circuit board.
The disc section is generally not broken and is well sealed. The water is estimated to be moving the
completely different interface with IDE (ATA), the IDE interface is standard interface of normal PC, and SCSI is not the interface specially designed for hard disk, is a kind of high-speed data transmission technology which is widely used in small machine. SCSI interface has a wide range of applications, multitasking, large bandwidth, low CPU usage, as well as hot Plug and so on, but the high price makes i
