TIA I have been reported about a similar crypto problem recently, when after upgrade and attempt to continue using the fs, first 4 bytes of many block get altered. Probably your case is a similar one. If you have provided me an access to the fs (restored from the backup) and I have confirmed the idea, I could probably write a hack to pull out more data. -- Thanks, Vitaly Fertman
