Desktop or Laptop ?

A USB hard drive is a portable external storage device that works just like a conventional hard drive. The device is simply plugged into a USB port on your computer as you would connect a flash drive. Unlike a flash drive, however, a USB hard drive can store a much larger amount of data. If your computer will not recognize your USB hard drive, you can try troubleshooting steps to resolve the problem.

Plug one end of the USB cable into the port on your hard drive and plug the other end into the USB port of your computer. Ensure that both ends of the cable are connected securely. Or even get a usb 3 lead. USB 3 card will provide more power when needed to the device to gain maximum throughput and conserve power when the device is connected but is idling http://blog.premiumusb.com/2010/09/usb-2-0-vs-usb-3-0/ Open "My Computer" (Windows XP) or "Computer" (Windows Vista/7). The USB device should be listed as "removable disk" once it is plugged into the computer. If it is not listed among the available drives on your computer, proceed to the next step. Ensure that the data cable is working properly. Sometimes they become faulty due to overstretching age or heavy objects sitting on top of them. Try another USB cable if you have one available. Disconnect all other USB devices from the computer as they may interfere with the operating system detecting the external hard drive. Reboot the computer if the USB hard drive is still not recognized. Plug the USB cable into another USB port and check to see if the device is detected. If you are using a USB hub, remove the device and plug the external hard drive directly into a USB port. If the computer still fails to recognize the device, the external hard drive itself may be experiencing a hardware problem. Check the status of the hard drive in the "Device Manager" window. Under Windows XP, right click "My Computer" and select "Device Manager." For Windows Vista and Windows 7, click the "Windows" button in the lower left corner of the screen, then type "Computer Management" in the search bar and press "Enter." Select "Device Manager" in the "Computer Management" window. In the Device Manager window, click the "+" sign that appears beside "Disk Drives." If the external drive is not listed, click "Other Devices" in the Device Manager window and see if an "Unknown Device" appears. Windows 7 First, please disconnect all USB devices and then perform the following steps:

Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.

In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".

Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".


Then, restart your computer and Windows 7 will reinstall all USB controllers automatically. If the hard drive that has failed is the same one that you are trying to recover from might the reason that you are getting this error. This could be an issue where the part of the hard drive you are trying to access is corrupt and not accessible which would explain the reason that it would let you access the other partition. Now I have seen cases where Malware can break the link of a Hard Drive. So let's try a couple of steps. Let's go back in to "Disk Management" Lets right click on the partition that you are not able to access and select "Change Drive Letter and Paths" Now try selecting a new Drive Letter. This will restore the path if it has been broken. The external hard drive may have been detected but the device is not working properly. If it is still under warranty, take the device to the computer store where it was purchased to have it repaired or replaced. Hope this helps.

External harddisk not getting detected


click start control panel administrive tools ,computer management ,device manager look through all of your devices if you see a yellow question mark?or exclamation mark ! or red x
right click to reinstall drivers or
if you can see your usb but its not working
ports(com&lpt)right click update driver
sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,
check the USB leads that attach to the motherboard usually red-white-green-black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems also make sure the computers Ram and Cmos battery are securely seated
hope this helps

My pc doesn't recognize my verbatim 1000gb external hard drive, error "unknown device"


Did the 1000gb external hd come with instructions?
Did you read them?
Did you Install The Software for this Device?

If not. Try plugging it in all the usb ports.
Try shutting down the PC, when it's off plug in the 1000gb external HD,
Restart the Computer, If Windows still dosen't recognize it, then it's most likely defective, and should be returned. Try purchasing a higher quality brand.

Please trouble shoot by trying the device on another laptop.

If it works on another system, it simply means it is not compatible with yours and you have to get a device that is compatible with your toshiba system.

Good try.

Are you using an external power supply for the disk? If not, you might be overloading the USB port. It should not happen, but USB ports are limited in the amount of power they can output. Especially laptops might face such problems.

Do other USB devices still work on those USB ports? If so then the port is at least not broken.
Sometimes you can uninstall and reinstall the USB hubs and controller devices in the Device Manager to fix USB problems.

Seagate external hard drive problem


Hello, Did you try to use this drive on another computer? Did you have the same problem? Did you try using a different cable? I would try these things first in order to determine if the problem is with the drive or with the computer. Good Luck! Dr. Know
