Hi, i just bought a Seagate Mommentus 5400.3 160GB HDD 5400 Rpm, SATA, 2,5" Note book Harddisk to replace the original 100GB on my MBP i already learned how to open the casing from ifixit.com. however i got a question to ask before i jump to it. I set a login password on my current MBP, now if i change my HDD , will i able to see the data on my old HDD provided i put the old HDD on an external casing ? i'm afraid because i've set a password to my old HDD then the data on it wouldn't be accesible. can anyone clarify on this ? thank you very much.
