Thanks so much for the detailed reply, Ted. And no need to apologise - no lost Ph.D. thesis or anything! I have a backup of the most important data. But there was over 3T of data and my backup capacity is only 500G, so there's still a lot that will be lost. I'll give photorec a try. It's very lucky I have the backup - most of the critical data is encrypted with eCryptfs, so photorec wouldn't have been able to help there. Really appreciate all the work you've put into Linux and the filesystem over the course of your career. I've been using and administering Linux systems for 13 yrs and this is the first time I've experienced major ext2/3/4 corruption that hasn't been the fault of hardware, so I'm still a happy customer, so to speak.
