That's normal for Windows. I'll just leave it at that but comment that I don't leave thumb drives attached when I don't need them. My use of such drives is backup and if they were attached when the terrible virus did it's deed my backup would vanish. So I don't do that.
... but plays CD with no problems.
I leave the blank CD in the drive during the reboot and then can burn ok.
Using Windows XP Home, 1.6 gig processor, 1 gig memory.
For some unknown reason, when playing or burning a CD, at least two thumb drives will be accessed.
Your help will be appreciated.
