, the Seagate SATA3.0 hard drive has the same performance as the SATA2.0 hard drive in the average speed test, and also leads the western data 100 million to the Raptor hard drive. Visi
mode, in fact, the serial technology is faster than the transmission speed of parallel technology.
Easier cabling-the flat, wide line of SCSI cables will no longer be used.
Wider scalability-compatible with SATA.
Lower costs-with the advantage of simplifying the internal connectivity design, you can reduce design costs by sharing components.
Look at this picture, this is the image of the SAS hard drive. Th
Q: I installed a couple of hard drives a few days ago I loaded two hard drives onto an IDE line, and the hard drive was not recognized. Later, the main disk and CD-ROM installed together, found the hard
drive connector line instability, hard disk physical damage.
Processing method:
One, CMOS caused by the fault
The correct type of hard disk in the CMOS (that is, the BIOS system) directly affects the normal use of the hard disk. Today's machines support the "IDE Auto Detect" feature, which automatically detects the
Introduction to Interfaces
IDE interface
(Integrated-drive-electronics) is now commonly used external interface, mainly connected to the hard disk and optical drive. Using 16-bit data parallel transmission mode, small size, fast data transmission. An IDE interface can only receive two external devices.
The IDE's English is all called "Integrated
1, the system does not recognize the hard drive
This type of failure is more common, that is, from the hard disk can not start, starting from a disk can not enter the C disk, the use of the CMOS automatic monitoring function can not find the existence of the hard disk. Most of this fault occurs in the connection cable
instructions on Jumper settings on the hard disk surface. Taking Seagate hard disk as an example (8), there are four main settings: "Master or single drive" (it indicates that the hard disk is set as the primary disk or only one hard
hard drive lights installed in the disk control array cabinet turned red, The system also prompts that the logical hard drive and the physical hard drive are not detected. I am not at ease, restart the computer system, and in the
What to do if your laptop can't find a removable hard drive:
System-related Setup problems
Do not assume that as long as the motherboard has a USB connector can use the mobile hard drive, but also to see if the system support. Windows2000, Windows XP and the above version of the system can directly support the mobile
computers often do not detect the hard drive what to do
The computer often does not detect the hard drive solution one:
There are several reasons for these:
1, the hard disk itself has a problem, may be broken, with tools to detect, bad can only send repair.
2, the data
What to do if a mobile hard drive can't be identified by computer
Solutions for mobile hard drives that cannot be identified by the computer:
Method One: System-related Setup problems
1, do not think that as long as the motherboard has a USB interface can use the mobile hard disk, but also depends on whether the sys
Sata's full name is serial Advanced Technology attachment (Serial Advanced technology Attachment, an industry-standard serial Hardware driver interface), which is made up of Intel, IBM, Dell, APT, The hard disk interface specification proposed by Maxtor and Seagate Corporation. The Serial ATA 1.0 specification was formally established in 2001 by the Serial ATA Board of Intel, APT, Dell, IBM,
Top 10 hard drive saving strategies
In order to effectively save the data in the hard disk, in addition to regular backup work, we also need to learn how to save the hard disk when the hard disk fails, or extract useful data from the bad area, minimize the loss.
