hi i have an external HD...Seagate FreeAgent GoFlex 1 TB...it is working smoothly on my laptop and other computers..however as soon as i want to connect it to my desktop, it is not being detected. My desktop has win 4gb ram and an intel mother board...plzz help as it is very wierd!!


Connect some other USB device (keyboard? mouse? memory-stick?) to your desktop?
Are those devices detected? If not, then either:
* the USB port(s) on your desktop are damaged,
* the device-drivers for the USB ports on your desktop are not installed.

Try connecting it to a different desktop/laptop, to see if the Seagate works at all, on any desktop.

My laptop XP is not detecting Transcend StoreJet 25 External HD 500GB, but in desktop XP it is very well detecting and working. Pls let me know the solution for my laptop


USB devices draw electrical power through the USB cable.

Sometimes, the power-output from a USB port on a laptop is _less_ than that of a USB port on a desktop computer.

Hence, there are "Y" cables -- connect to two USB ports on your computer, and to the USB device at the other end, to draw more current.

Which manufacturer of laptop?
Which model-number?
Which Operating System?
Do other USB devices work when connected to the laptop's USB ports?

I have power to my W.D. but it will not connect to my computers


Check the power cable The My Book and Elements desktop devices use a power adapter to operate the drive and hardware. Portable devices rely on the data cable for power and data.
  • Check the power cables are well seated in the external drive (applies only to Desktop external drives), and also the AC socket the power adapter is connected
  • Connect the device directly to the computer. For troubleshooting it's best to ensure the data cable is connected directly to the PC or laptop. Do not connect the device through a non-powered USB hub. Similarly make sure the power adapter is connected directly to a wall outlet, to rule out a degraded surge protector or power strip
  • If this is a My Passport or Elements Portable drive, ensure the data cable is connected securely to the drive, and the computer's USB port. For troubleshooting only, do not connect via a USB hub, to rule out power related concerns
  • My Passport and WD Elements Portable devices may benefit using a Power Booster Cable to use two USB ports, in order to provide extra power to the device
  • Use a USB hub with its own power adapter. These units provide 5V, and up to 1000mA to each USB port; and may be a good alternative, if a Power Booster Cable is not available
  • Test with another power adapter. Take note of the input requirements at the power port of the desktop device for voltage and amperage. Be sure the output of the power adapter does not provide voltage higher than the device's input requirements. Higher amperage will not harm a device, but higher voltage will destroy a device

Check the data cable Data cables can degrade over time from bending and flexing. The connectors can get bent, or the internal pins may corrode from moisture or other contaminates.
  • Use a different data port
  • Use a different data cable
  • Use a different computer, if possible

My ASUS computer will not read my SONY memory stick...my Asus Laptop will and my Dell Desktop will but not the Asus Desktop


You need to go to Device manager, remove ALL USB devices the whole thing.. remove and uninstall driver. then, reboot. Now at next desktop, try using the USB stick then, this often "Fixes" any problems. (Windows will auto-install the entire USB layer all again at boot up)

failure to read USB connected storage drives


What I have seen with some computer models, is that the USB port cannot deliver enough current to run some devices.

If possible, use an external drive with its own power supply and see if it will work. Most likely it will.

Also, try a powered USB hub. I found that most of the time, a powered USB hub solved many problems with having enough power for some external USB devices.
