The other day a client calls up and says she keeps getting a “Windows – No Disk” window, that will not go away no matter how many times she closes it. I then asked when did this problem appear, in which she replied “after I pulled out the USB Flash Drive”. So at this point I was thinking that some files she was working on, wanted to save themselves to the usb flash drive and could not since the drive was not present, thus causing the annoying “No Disk” error. I then instructed her to save her work elsewhere on the hard drive and restart her workstation. 
Unfortunately however, after she restarted her workstation and logged in the error continued to pop up!
Since the restart didn’t solve the issue, I knew it was time pull out my best tool in the shed “Google Search”. After a couple google searches and a couple forums, I found out that the reason for this error is due to a usb driver that became corrupted during installation. The solution is to uninstall the usb drivers and reinstall them.
Once I had uninstalled all the usb drivers in Computer Management and restarted the workstation, the “Windows – No Disk” error appeared no more. Mere mortals can only guess why the usb driver became corrupted in Windows, but thanks to google and a post on technet this XP annoyance was solved!
