Yup, I've done something similar when I used a PC with a bugged via
chipset which regularly broke apart filesystems under heavy load... I
used a tool named afick to index the whole disks (it stores md5 of
everything in a small db) and with some tinkering I was able to restore
everything from lost+found each time some filesystem went belly up
(once a month...)
