Usb flash drive can't be recognize anymore by the pc..

It will only show USB devices that have been formatted. Have you tried going into the Computer Management, Disk Management to see if the usb drive is recognized? Can another windows PC recognize the USB drive?

My reader will not read mine either. I use a usb key card reader. It used to read the regular old SD cards but the new HC card format wont work. This is due to UDF differences. You can try to reformat the card but then your camera or device may not recognize it anymore. good luck

Your problem could be any one of these issues:

1. Faulty USB port on PC: Try a different computer or laptop

2. Faulty USB cable: Try a different Cable

3. Corrupt memory: Fix by an expert required such as www.SaveMyUSB.com

4. Faulty connections on main circuit inside the hard drive: Physical Fix by an expert required such as www.SaveMyUSB.com

5. Faulty controller chip (worst case scenario) : Direct flash memory read required by an expert required such as www.SaveMyUSB.com

Hope this helps and that it is 1 or 2 as 3, 4 and 5 will cost you money.

Good luck!

Try to format the Jet-Flash, go to My Computer right click on the Jet-Flash and choose FORMAT.

Have you installed a scanner/another external USB drive since first trying your Flash drive? If so, try unplugging that and re-insert your Flash drive. I had this problem and a friend suggested this and it worked!

Hi. Here are the steps:

1. Plug your flash drive into a USB port on your computer.
2. If you use Windows, the flash drive will appear as an icon in the "My Computer" window, with a caption along the lines of "Removable Device" or "Flash Drive". Note: Please wait the first time you plug it in - Windows needs to "discover" the flash drive, and will essentially set itself up to recognize the device so that it's usable. If you use a Mac, the flash drive's icon will appear on your desktop with similar captioning mentioned above.
3. You can double-click on the icon to open the flash drive and see its contents. You can drag files from anywhere into that window, or over the flash drive's icon itself to copy files into it.

Hi ,

You can Uninstall the U3 system , link to uninstaller can be found at : http://www.u3.com/support/default.aspx#CQ3

once you uninstall it you can go back and reinstall the U3 system from the same website.

use device not recognized

it may be because of the usb port of the system or the usb of the pendrive.................
