I had the same problem. I droped mine and it seems to have messed up my hard drive. i replaced it today and my comp. can now reconize it. i have been trying to contact tech. support to see if it is possible to get the OS back on the PMP. if the Tech support ever picks up my call i will message back with the fix.

sounds like the battery has been allowed to discharge totally this is not good for certain types of battery despite what some people may think.. some modern bateries require at least a residual charge to keep it healthy enough to receive a whole charge

For Windows XP users: verify the following operating system requirements are met. - Windows XP SP2 or higher - Windows Media Player 10 or higher
Download and install the latest Windows Media Player if it's not installed.
For Windows Vista users: If the player is seen in My Computer when using MTP mode, but not showing in Windows Media Player. - Download the hotfix from http://support.microsoft.com/kb/939211. - Run the hotfix.
NOTE: If you are trying to connect to a Computer at work that is part of a network, there may be user right restrictions that are set to disable access to new hardware or stop any program installations. You may need to check with your IT administrator to see if this is causing the problem.
Next:-- Refresh the driver Connect the Sansa player to the PC The screen on your player should turn on, show 'Connected' and indicate the battery charging or full. - If the player does not turn on try other USB ports or on another computer if one is readily available. Ensure you are connecting directly to the computer USB port and not to a USB hub. NOTE: - If there is nothing showing on the screen and the player does show up in as a storage device in an explorer window, then the screen is just not working. If you receive the error "USB Device Not Recognized" on the computer, the player is most likely failed. Additional troubleshooting is unlikely to correct the problem.
Next - Check under Device Manager 1. Right-click My Computer, and select Manage. 2. Click Device Manager on the left pane. ffffff

That is because USB drives were not available in 1999/2000 when XP came out and there are limited drivers for them.
See if there is a driver on archos.com

Hope that explains it.
