I am looking to password protect my usb drive. I know that if I format a usb drive with OS X extended (journaled, encrypted) I can password protect the drive. If I plug it into any mac it was prompt me for a password. And it won't be readable on a PC. If I format the drive as exFat or fat I am able to right click on the drive and choose "encrypt". Does anyone know what will happen to the drive when it is put in a PC? Will it prompt the person for a password on windows?
