With hard drive prices continue to move lower. Many of my friends to be able to easily store large files, have bought a USB mobile hard disk interface. Many friends in the process of mobile hard drives may encounter various problems, leading to not work properly. Much part of the experience with a mobile hard drive, in your own machine to normal use, but for the machine can not correctly identified. HDD can not be used if you encounter problems, people are very unhappy, and had just bought for the convenience of the product Fandao no longer convenient. Author as a friend to solve a variety of failure summarize some relevant experience, here simply to tell you about the recurring minor problems, you want to help a friend
First of all, those who have never used USB external device a friend to say what a simple USB interface on the motherboard open question. At present, most motherboard BIOS by default, the motherboard USB interface is open, so do not do any operation. But there are still some old motherboard or motherboard manufacturers in the motherboard manufacturers did not open the USB device, so we need here is a simple look.
Set is simple, start by DEL or F2 (according to different motherboard chipset motherboard BIOS into the different ways) into the motherboard's BIOS setup options, select the "PNP / PCI CONFIGURATION" section press Enter, and the "Assign IRQ For USB "one set to" Enable ", set up after the press" F10 "key to save and exit, so the system can be assigned to the USB port available interrupt address.
Common mobile hard disk failure and analysis solution:
1, the system can not correctly detect HDD
Fault Description: Hard Drive right into the computer's USB interface, hear the hard drive issue, "Kacha, Kacha" sound, the hard disk light keep flashing, the system can detect the normal use of the USB devices on my computer can not see the HDD icon.
Fault Diagnosis and Solution: The system can detect the USB device, indicating the system is able to detect a normal mobile hard disk. The light kept blinking observed, accompanied by "Kacha, Kacha" sound, indicating mobile hard disk and not damaged. Will move to another hard disk for a machine, which can be used normally. According to this, judgments are caused by lack of USB power, so the mobile hard disk PS / 2 power supply interface and USB interface, while inserted, try moving the hard disk after all, the problem is resolved.
Experiences: Some computer motherboard USB interface-voltage, when the system is not mobile hard disk drive letter appears, might be transferred to the PS / 2 port power supply a try. In addition, if mobile drive long-term work in the absence of sufficient voltage, may cause hard disk damage. Therefore, the use of mobile hard disk, be sure to pay attention to connect its power cord. At present, some thin and light mobile hard drives do not have the PS / 2 power supply interface, and careful observation will be found to have two USB interfaces, two USB interfaces, this is an article, and its initial purpose of the design is also used to solve a single the problem of insufficient power supply, so if the above problem when using the two USB interfaces can be inserted into a computer while the USB interface.
2, USB2.0 USB1.1 mobile hard drive not recognized when used
Fault Description: HDD LED does not light, carefully observe the hard disk USB interface and interface cable, pin no exception. Open the hard disk box, tray body parts and no surface discoloration and abnormal phenomena; Hard disk box with no deformation of the interface pins. Only HDD hard drive instead of the interface modules into boxes, into the computer, mobile hard drive has returned to normal. Box and then pull into the hard disk, mobile hard drive was not any reaction.
Fault Diagnosis and solution: from the above operation, we basically rule out the possibility of the mobile hard drive failure problem in itself, suddenly remembered that he used the computer USB1.1, and USB interface, suspected to be caused by inadequate power supply, then move the hard disk for to other computers on the trial, troubleshooting, mobile hard disk as usual.
Experience: USB1.1 interface, power supply often have to be smaller than USB2.0, USB1.1 interface, so if the computer in use USB2.0 mobile hard disk, be sure to pay attention to power supply PS / 2 or dual USB interfaces to be inserted into the computer. Others provide only a USB2.0 mobile hard disk interface, such cases only if they can not use the USB2.0 interface on the computer used. However, as this mobile hard drives are thin, and I believe there is no problem, but remember that interfaces directly to the motherboard to the USB interface, do not use the chassis front of the USB interface, because these interfaces is to use the data to extend the line to provided, so the transmission process will now be loss. Moreover, some poor chassis USB interface design is very poor, but also lead to an important aspect of a variety of reasons.
3, the NFORCE motherboard mobile hard disk error occurred during read and write operations frequently
Failure Description: There is a computer motherboard using NFORCE2, WINDOWSXP system is installed, use USB2.0 high-capacity mobile hard copy documents, often prompted to copy the file error, and then move the hard disk drive letter disappeared, to re-plug USB connection can not be used to replace other USB2.0 mobile hard disk failure still.
Fault Diagnosis and solution: WINDOWSXP comes with USB2.0 drive in use in practice there are compatibility issues with NFORCE2 motherboard, the performance of its failure from the USB2.0 device error when copying large files, and move the drive letter disappears The solution is to first install Microsoft's SP patch before you install the nForce2 chipset drivers, and finally download and install the latest version of the USB2.0 factory driver.
Experience: in some old used NFORCE chipset motherboard, making copies of large volumes of documents will be out of this situation, there are some other old VIA chipset motherboards will also appear similar, we just download the motherboard timely The latest chipset drivers and patches, will be able to solve this problem well.
