vim: recover an unnamed file

guys:
My PC (ubuntu) just restarted by itself due to the (stupid) overheat
issue, again (I couldn't find a solution on that in a year..)

but regardless, I had a file that I had been editing for quite a while.
all of a sudden the PC reloaded, now I'm wondering how can I recover
that file.

I tried both of the following method , but none of them give me the
right file.

one thing I've notice that if I'm in different folder, vim -r give me
different files. I tried to change to different folder and invoke vim
-r, but still failed to find the right one (per the timestamp) for me...

any other good ideals?

maybe the last resort, do I have to grep from the whole harddisk for this?

and, what's the best practice to solve this issue in the future (lesson
learned for me: always use a named buffer ) ?
