Hi there,

as far as i know there are two ways to recover one's btcm first: having the private key, second: getting the wallet.dat - right?

i don't have access to the private key, but i do have access to the hard drive, the wallet.dat was on (althought deleted, might be overwritten, might be not).
what ways do i have to
a) recover the wallet.dat
b) get access to my btc again?

i do have access to a linux (ubuntu), windows (7 or 10) and mac (current version ios) system.

thanks in advance.
