I have already had a couple of customers on support experiencing this issue, all of them having either a card reader connected on a USB port or having USB extension ports on their display.
To start, this is a Windows system issue, not a TDM issue and appears when you have any application searching for Paths/Drives on startup. I can only provide googled solutions. On support.microsoft.com/…/330137, you can find several articles by Microsoft on this issue. The error itself is not anyhow dangerous, it’s just itchy.
You can either turn off this annoying error message (not solving the original cause):
- Open regedit (Start > Run -> Type in “regedit” -> Click OK, or in Start, type “regedit” in the serach box and press Enter - Win 7)
- Navigate the category tree on the left, find:
- Now look for ErrorMode key on the right side panel
- Double click on ErrorMode, change the ‘value data’ to 2 and click on ok.
or you can try to resolve the issue, which may be caused e.g. by a removable/network drive not currently connected (or a card reader/DVD drive) with assigned letter C or D (even formerly, not now).
Follow steps explained in Microsoft knowledge base on the link support.microsoft.com/…/330137,
or you can change a drive letter (re-map the drive) as explained e.g. on pcsupport.about.com/…/change-drive-letters-windows-7.htm.
