I came from Windows XP about a month ago. I finally switched. And I love my MacBook Pro to bits. Will never go back to XP (I was a hardcore XP user) I found a folder on my External HDD and for some reason it has a lock on the corner, everytime I try to trash it. It tells me to type a password. I do so. And then nothing happens... Seriously... Nothing.. I'm sure it was the right password because any other password is says "Wrong Password" It even makes that noise when you trash something except nothing actually goes in the trash. I go to "Get Info" and it says under "Sharing & Permissions" "Read-Only" I don't know why it says this. I didn't exactly "Lock" anything when I was using Windows XP. I may have Hidden the folder but non of the other folder became like that.. Any Ideas?
