Whenever i insert my external hard drive to the USB port of my desktop, the desktop flashes a message saying USB not recognize. And the hard drive does not work. i do not know to make it work..


The most common cause of this in my experience is not enough amperage available at the USB port. If you're using a front/top case port, try switching to one of the ones at the back of the case that is connected directly to the motherboard. If that doesn't work, you can use an externally powered USB hub, which usually solves the problem as long as the hub has a 2A or better power supply.

Hope this helps.

I cannot get a SanDisk flashdrive to go into either of the USB ports on my new desktop computer. I am using the USB ports located on top of the computer


To test the functionality of the usb ports in front of the computer
1. Insert another flash drive or another usb device like a usb mouse on front the computer 2. If it detect the usb device that means 2 things flash drive might be bad and the front usb port is working 3. If it does not, It means that the flash drive might be bad or the usb port is not connected to the front panel of the computer 4. Try also inserting the flash drive at the back of the computer see if the usb drive is detected in all ports 5. Check the BIOS for any usb port associativity

This has happened once before and I think Windows XP fixed itself after some time, but I don't know how. While transferring files onto a 4gig flash drive, I got an error message that one file could not be...


I have seen USB ports fried like this, by USB devices. It can render them usesless.

What you can try, is go to the Device Manager, and uninstall the USB ports there. Then go up to Scan for hardware changes. That should automatically reinstall the drivers, in case they got hosed.

If that still does not work, they may be dead. I have seen it where even a device light works, which means there is power on the USB port, but the communications part does not work.

In a desktop PC, you can get an add in PCI card, and route the ports to the front, that is a possible fix for you.

How do I get started using a USB flash drive and how do I set up a security system?


hey, heres something that would help u:  Copying files to a flash drive on a PC:
  1. Open My Computer and see which drives are shown. Most computers, for example, have a hard disk such as a C: drive and a few removable storage devices such as a floppy drive, a CD-ROM drive, and perhaps a zip drive. 
  2. Insert the flash drive into the USB port and watch to see where the USB flash drive appears. Most will appear as removable storage, but some will instead appear as hard drives. Note the name Windows is using to refer to the flash drive ("Removable Disk (G:)," for example).
  3. Open My Documents or the location from which you want to transfer files to the flash drive. Select the files or folders you want to save to the flash drive by left-clicking on them. To select more than one, hold down the CTRL key while you click and select all of the files you wish to save. 
  4. Right-click on the file(s) or folder(s) you selected, then select Send to, then select the name you saw appearing in My Computer for the flash drive ("Removable Disk (G:)," for example).
  5. When the copying is finished, do not immediately remove the flash drive from the USB port. Instead, left-click on the Remove Hardware icon toolbar.gif located in the System Tray. A window containing a list of the USB devices will appear. Left-click on the Safely Remove Mass Storage Device line that matches your flash drive (for example, Safely Remove Mass Storage Device - Drive(G:)). 
  6. When you see the following message appear in the bottom left toolbar, it is, as it says, safe to remove the flash drive from the USB port; you may close the message or ignore it, as it will close itself automatically:
