There are 3 PCs at my office - 2 HPs and 1 Acer. All 3 machines have inbuilt card readers. My HP and the Acer both run Window 7 Enterrpise. The second HP runs Vista.
In explorer on my PC. In the left hand pane, I see my local disks, my DVD and mapped network drives. I do NOT see the removable drives as there is no media inserted into any of them - BUT they do show up in the right hand pane under the Devices with Removable Storage section with the drive letters assigned.
On the Acer and the other HP, these Devices with Removable storage also show up in the left hand pane (with their drive letters) inbetween the local discs, DVD and mapped network drives - even though there is still no media inserted.
Why would this be? This doesn't sound like much of a problem, except for that I am writing a program that tries to access partitions based on their GUID. On my machine, the removable devices are ignored unless they have media inserted, and on the other 2 machines, I get an error message because there is no media inserted!
