If i use an external HD as time machine to backup all the data with my MBP, can i still use THE External HD as a NORMAL HD work with other computers.
And if my MBP got crashed, totally damaged, Completely dead, can i restore all the data in another Mac via external HD
Or the time machine can only be used to find data while can't be used as restore HD.
