I been testing this product at work with B&R industrial PCs using compact flash media as the boot drive. Since drive C: is protected by EWF (enhanced write filter), I have to disable before or commit the changes after an update or the recovery process fails. I have to assume Acronis writes some type of script to do the backup operation and if the drive is protected, there is no script to follow after restart. I have successfully tested the local and remote backup to networked computers using the commit option as a pre command, however, I have not been successfull running a recovery locally using the Echo Workstation software using the same option. The system restarts and the cursor flashes for a while, then I get "disk not ready". Does Acronis or anyone in the forum used there products on drives that are protected by EWF or used compact flash cards as hard drives? Just looking for some feedback.
