If the data is still available, they can get a warrant to retrieve it.
If they want to hack in, they could do that with a warrant too, based
on other technology that has been used in the past. (bugging phones
and retrieving data from GPS units in cars)
The scary warrant is a FISA warrant, provided by a secret court and
seldom ever refused.
