I suddenly started getting the following error (with no changes to the server): "E00070021: Cannot access drive. Cannot create the image of the logical drive D: because it is currently in use b running applications or the logical drive contains bad sectors." Do we know what Acronis is choking on or how to find out? For the sake of argument, assume I'm already using the latest version of Acronis TI and the drivers. This is a production server. I have no hope of being able to reboot, uninstall/reinstall, update drivers or generally interrupt my users to experiment with this (at least for a while longer than I'm willing to go without a new server image).
