meta.db

That is bad.
But are you sure it is a HW i/o error? What does dmesg and/or syslog tell?
I would expect the flash disk controller to handle 'bad sectors'.

Did you try a cp or a dd? To move that file to other location as it might be that this meta.db (locked by aegis?/metadata user, ) cannot be moved by OS to other disk location (but even that I would expect to be handled by the controller).
So I am guessing only, please elaborate and try to give some more information.

Another approach: as it is a sqlite DB, you could try to dump it and load it to a new file. Move that file later to correct location and give rights...
