SanDisk dual 32gb...works on droid, but not on pc

Hi,

I just bought a Dual connector 32gb.  Great idea!  It seems to talk to my phone, tablet, etc all just fine through the mini usb.  But when I plug it into a laptop it wants to format it, or, it works for a minute then gives some kind of write error.  I have better luck with my desktop,  I wiggle it a bit when it fails, and it works for a while - or unplug replug.  All the PC’s are Windows 7 Pro.   Any ideas?

It is possible the ports on your pcs are dirty or oxidized.  Try cleaning them with emory paper if you can.  One or two swipes of the contacts, don’t get carried away with it.
