[Resolved]  Western Digital / External Hard Drive — External Hard Drive Not Working

western digital/External Hard Drive — Not working

my hard disk is not connecting with pc

my hard disk is not connecting with pc .
Yes its only 5 min connecting & then disconnected automatically.

suggest me,

External hard drive can not be recognized, are more common on computer failures, what’s the reason caused this failure?

1, Setting the CMOS parameters

If you never used the USB external device, there may occur the case: the system can not detect USB hard drive even if the driver is properly installed, which was mainly due to the motherboard CMOS default port is closed, if not set to open state, it naturally Windows can not detect the external hard drive. In order to solve this problem, we can re-boot into the CMOS settings, and set “Assign IRQ For USB” to “Enable” in “PNP / PCI CONFIGURATION” column, now the system can be assigned to the USB port available interrupt address.

2, Power shortage

As the USB drive need to consume some power when it at work, if directly through the USB interface to take power, the power supply may be not enough. Thus, almost all of the external hard drive comes with a separate external power supply or a PS2 keyboard to take power transfer interface, at this time you should connect external power supply or through the transfer cable ps2 connected to keyboard to ensure that it have provided adequate power to the external hard disk, recommended that you should ensure the external hard drive have adequate power supply when you use it, otherwise, the external hard disk is likely to be damaged due to insufficient power supply.

3, USB extension cable fault

USB interface type does not match the external hard disk interface, this case caused it can not be used. For example the standard USB interface of the computer configuration is 1.1, while the external hard drives purchased are USB 2.0, which requires the cable connected computers and external hard disk must support USB 2.0 standard. Because high-speed mobile device plug in a low-speed hub, the device may not be properly installed, and some people use external hard disk while using USB flash drives, For convenience, they directly used USB 1.1 standard cable that supplied by USB flash drives, as a result, the USB 2.0 standard hard drive not be recognized correctly. Just replace it by the USB 2.0 standard cable can solve this problem.

4, Windows version is too low

Pre-Windows 98 operating system does not support USB peripherals, so in any case to install the driver, set the CMOS parameters are unable to make normal use of external hard disk. In this case, one solution is to upgrade the operating system up to Windows 98, another way is to Microsoft’s official site, download the appropriate patch to make it can identify mobile hard disk.

5, The system is set incorrectly

When installed driver, the external hard disk icon will be seen on the Device Manager for some Windows 98 users, but the Explorer does not include the corresponding letter identification, which is improper system settings. In the Device Manager, double-click the Hard Drive icon, and click the pop-up window in the “Properties” button, and you could see disconnect, could be deleted, synchronous data transmission and Int 13 unit four options, of which “could be deleted ” is no tick in front of the system, and simply check this option to restart your computer, you can see in the Explorer, the new external hard disk drive letter.

While the failure of the external hard disk does not recognized are more the reasons, but generally not the USB interface or external hard disk’s own fault, so it requiring us to consider some more from around the association when exclude it, I believe you can successfully use the external hard disk.
