I've sent an email to support, but I figured I'd check with the forum to see if anybody else has experienced this problem and has a solution. My main Windows PC is running TrueImage 8.0 Enterprise build 1201. I have an image of a Linux system that has a ReiserFS filesystem. If I mount this image in Windows, it assigns a drive letter, but then the dialog indicates that it is still busy. After about 60 seconds, I get an error message saying that it could not assign a drive letter, and the image is unmounted. TrueImage is making an incorrect assumption that if Windows cannot understand the filesystem, then something failed with mounting the image. Even if Windows cannot read the filesystem, some third-party applications can, such as Yareg: http://yareg.akucom.de/ In the past, I have been able to have ATI (not Enterprise version) mount a reiserfs image successfully in Windows. The drive letter is there, but Windows explorer cannot browse to it (obviously). However, using Yareg, I was able to explore the filesystem and restore files from it as needed. However, with ATI Enterprise I only have about 60 seconds to do the above. This is the time between when ATI mounts the image and assigns a drive letter and when it gives the error saying that it cannot assign a drive letter. The mounting logic needs to change back to the way that it was before. Even if windows doesn't understand the filesystem, ATI must *NOT* unmount the image automatically with an error. I am not sure when this regression took place.
