The other day I started a restore of an image using v9 Home (3677). A couple of minutes into the restore I realized that I had selected the wrong image. Since it takes 45 min to restore the image I decided to Cancel the restore and select the correct image. BIG MISTAKE! My drive was no longer available! Had to have IT reformat the drive and restore the original image. Since I'm not yet ready to give up on Acronis I decided to upgrade to v10 Home (after having only bought v9 ~6 months ago ). When I went to install v10 I ran into the same problem I always run into every time I upgrade Acronis... the BSOD! The BSOD is caused by an incompatibility with a driver called FILTER.SYS and the Acronis installer. The workaround I've been using is: - Rename FILTER.SYS to FILTER.SYS.SAVE - Reboot Windows - Install Acronis update - Rename FILTER.SYS.SAVE to FILTER.SYS - Reboot Windows The Acronis installer is the only program that has a problem with this driver. I've been trying to find an updated FILTER.SYS file (mine is 11/25/2004) to see if that will fix the problem but I haven't found one yet.
