Otherwise, I'm out of ideas.
So am I, I'm copy all the files of the drive and I'm going to re-make the file systems.
... and now, 16 hours later I'm seeing some errors.
I've run 'mkfs.ext4 -c -c /dev/sdb1 and on the *second* pass I'm seeing some errors. The first 0xAA pass got no errors but the pass that's running now, writing 0x55, is getting some errors. So, presumably, that's what the problem is. However it's strange that nothing else was showing any errors, SMART reported nothing at all and I've not had any errors reported while using the disk, not that I've seen anyway.
The disk is in my backup system in the garage ('off site' the garage is a fair way away from the house). The only corrupted files were in a backup copy of my previous desktop system. My daily incemental backups were all absolutely fine.
So I guess I just need to buy a new disk drive. I can maybe use the existing one for short term storage of videos and such.
