Hard Disk Data Cable Problems

Http://www.px-hc.com/showthread.php? P = 9515 hard drive data cable

Fault symptom 1:
Once in the installation process for the customer, the device crashes every time it is installed halfway. There are no rules. Sometimes the hard disk cannot be found during startup.
Solution Process:
I thought it was a hard disk problem. I switched to the warehouse for a few new ones, but I didn't need to use them. I tested all the hard disks I got on other machines. Later I suspected that it was caused by the drive failure. I could not change the drive and system disk. I finally changed the root data cable with my try. The fault was solved !!

Fault symptom 2:
When I upgraded my computer, I changed the motherboard and 40 Gb hard disk. Because there was important information on the previous drive C, I used gohst to directly restore the previous backup to the new one, as a result, a lot of English was displayed on the boot screen at startup. The system prompts that the file is missing.
Solution Process:
I thought it was a problem with the ghost image file. I simply retried the system. During the system creation process, I had a blue screen, but I didn't pay attention to it. After the installation, when the system is started and used
And the system is prompted to lose files. Later, I suspected that the data cable slot of the motherboard would not work, but I still could not do it if I changed the motherboard. Based on previous experience, the data line was replaced and the fault was solved. It was originally During the computer upgrade process and I took it as needed.
A data line is used, and the result is a bad one, resulting in file loss in the system.

Fault symptom 3:
One training course computer has two hard disks, one of which is the system disk, the other is the file backup disk, and the other is the optical drive. One day, the system prompts that one of the hard disks cannot be found.
Solution Process:
Only one hard disk with the system is installed, and the other and the optical drive are not installed first, and the boot is normal. Next, plug in the optical drive, and the boot will also be normal. Finally, add the hard disk as a backup to another data line, but the disk is not recognized.
The disk is connected to the data line but can be found from the disk location. We all know that two devices can be added to an online device, one master disk and one slave disk, and the jumper on the hard disk must also be configured as a master/slave device. Then, the corresponding settings are followed.
The system still cannot find the primary disk. The analysis may be caused by a problem that occurs when the data line is connected to the primary disk. Change to a new data line. Solve the Problem !!!

Summary:
Data lines are easy to ignore, but they may cause some inexplicable problems. During installation, do not purchase data lines with poor quality to save money! In addition, I have encountered some uncommon problems. I often suspect that some of the places we think are impossible, and there will be unexpected gains!

Strange Fault Caused by serial hard disk Cable
I would like to explain the serial hard drive, which is SATA for short. It adopts the point-to-point data transmission mode. The external transmission rate reaches 150 Mb/s and supports hot swapping technology. The use of serial hard disks in PCs greatly improves the overall performance of PC systems and the transmission bottleneck of Hard Disk interfaces.
As a new interface standard, Sata has made great improvements in hardware connection and has become a selling point. As a new interface standard, Sata has made great improvements in hardware connection and has become a selling point.

The figure shows the comparison between the SATA and PATA connection lines.
The above is a comparison between the SATA connection line and the PATA connection line. Obviously, the SATA data connection line is only about of the PATA data line width, and the data line is small and easy to install, but it also has a drawback, that is, the SATA connection line and the hard disk and the interface with the motherboard are loose.
Because of the need for repair, my machine is not covered with the box cover, the various connectors inside are also often pulled out, often accidentally, the hard drive cable will fall down.
Recently, I found a strange phenomenon on my computer, that is, when I click some files and folders on drive H, the computer will suddenly restart, I have no idea what causes such a fault. The restart was particularly serious this evening, so I made up my mind to clarify this problem tonight.
According to my understanding, the hard disk restarts for no reason, usually due to a lack of power. The power I use is the P4 power of century star, so there should be no problem with the power itself. Since the file running H drive causes the restart, the problem should be roughly in H drive, I scanned drive H and found no obvious problems.
Later, I considered whether the motherboard Power interface or the hard disk Power interface was loose, resulting in a lack of power. I checked all the power interfaces again, and the power interfaces were solid, during the check, wire the hard disk
Again. Suddenly another kind of hunch, is it caused by the looseness of the hard disk line, then the hard disk line is firmly inserted. Restart the instance and run all the files on drive H again. The computer will not be restarted and the fault will be rectified. It seems that string
The interface problem of the hard drive is really a failure of the manufacturer's designers.
