I have a mac mini with dual hard drives in it, one is a solid state 240 gb, & one is a 500 gb regular drive. I was trying to resolve an issue with the contents on the solid state drive, & I did a PRAM reset. when the computer came back on, I was logged into the 500 gb hard drive, I want to get back to my other hard drive. when I try to log out of my 500 hard drive, I cannot not because I do not know the password for it. I want to get back to my 240 solid state drive, it has all my documents & apps. both these hard drives have lion installed on them. I bought my mac mini like this, & I do not have nay installation discs with the os on them. I am the administrator for both hard drives.
