i am in the exact same predicament as mentioned on this thread. however, i can't reply to that thread because a post would return with a message saying that the thread is too old. anyway, the backup file of 236 GB is the only copy i have of the data now, and this data is essentially my lifetime work.. i had made entire backups of my windows partition before and it always mount properly after the "successful" message of creating the backup. is there a way to extract the files from the archive? i will happily pay for such a thing IF it works. the only thing i haven't tried is copying it to my local drive because, like in the other thread, i haven't got the space. i have tried copying the backup file to an external firewire drive and i still get the same error when mounting: i need all the help i can..
