Thanks for the suggestions...I tried both these suggestions and many
more and still no luck. One suggested deleting th eUSB and USBSTORE
keys in the registry. I changed permissions so I could do that and I
still cannot delete those keys. I put mys sandisk 16gb stick in
another pc runnig vista and it recognized it. I tried a frien'ds 32gb
stick in my 2 pc's... no luck on either pc. Very baffling! I hate
have to reload windows on my 2 machines that otherwise work just
fine. Any other suggestions?
