I have a Dell Precision workstation T3400 running Windows XP Professional. The problem I'm having is sometimes my camera cards will not open or be recognized when inserted into the memory card reader.
They are recognized within disk management meaning I can see that the machine sees them but if I attempt to right click and open and/or open from my computer it acts as if there are no disk in the drive. If I changed the drive letter then reboot it works as its supposed to. This happens with multiple cards. I've tested these cards with another computer and these problems don't occur.
