@codewiz This A3000 is gorgeous and your repair is unbelievable. Just, I'm not adept of retrobright (cause it doesn't last in time) but the result is lovely.
For filesystem, FFS is invalidating his structure if you reboot/crash during a write operation. Maybe it's not your problem here, but FFS is really a mess for that. I prefer to use SFS on my HD, even on my A1000 ;-)
