Was it v3.21 Build 205? I don't know what's up w/ the latest versions, but my snapshots (internal and external) are all getting corrupted when importing from an external drive or booting from current drive. Also every now and then I get a FD-ISR internal "23 error" message. I'm not sure if it's related to VSS service.....but the Raxco version(s) were very stable for me. Thanks in advance.
