Following up on out report from last time, several readers (including Greg Penetrante, Miles Baskett and Bob Patterson) have reported a similar problem with updating DiskEssentials from version 1.04 to 1.06: they get an "unrecoverable error in patching Code resource" when trying to apply the update to DiskRX.
Update: Kelly Leopard, of Total Recall, assures me that the update that is now on their web site will work correctly.
Bob Patterson also reports having received the following note from Total Recall: "DiskEssentials also has a few new features coming soon. We are adding DiskMinder and DiskBoot, and are in the process of completing an optimizer. We expect release in the next week."
