USB Drive Not Showing


I have a Dell Precision 470 with two USB slots in the front.  When I stick a device in there it does not get read.  For example, when I stick a jumpdrive in there Windows Explorer does not see it.  How can I fix this?

Thanks in advance.

Do the ones in the back work?  If so, the ones in the front may not be connected to the motherboard, and you would have to open the case to check.  If the ones in the rear also don't work, check the USB device on another machine; also check if your OS is up to the task.  WinXP requires sp1 or later, Win2K requires sp4.
It is easy to wire those front ports incorrectly. If they aren't plugged in and there are spare headers on your motherboard for them, use your mobo manual and be very sure you have it right. You can destroy whatever you plug in if they are incorrect.

Hi there,

Option 1 - Drive letter assignment
The drive letter might not be assigned properly or is shared with a fixed drive.
 - Plug in the USB drive
 - Right click on 'My Computer' and select 'Manage'
 - Click on 'Disk Management'
 - Look for the 'Removable Media' with the exact disk space as your USB Flash drive
 - Right-click on it and select 'Change/Add drive letter and paths'
 - Assign any available drive letter to it.

Option 2 - USB Bios not recognise
 - Right-click on 'My Computer' and select 'Properties'
 - Go to 'Hardware' and select 'Device Manager'
 - Did you see any yellow exclaimation mark? If yes uninstall it and rescan the hardware
