I have tried this out with two usb card readers now, and have gotten the same error for each.
Whenever I have the card reader connected (And I would like to have it connected all of the time) I get the following error:
"svchosts.exe - No Disk: There is no disk in the drive. Please insert a disk into drive \device\Harddisk1\DR33"
The Harddisk number changes between 1,2,3 and 4 (for each card slot) and the DR also changes- I assume for card types.
If I have a card in one of the slots, errors no longer show up for that slot, but continue for the rest.
I have Windows 7 Ultimate 64-bit.
The current card reader is a Kingston Media Reader.
