Password for encrypted external hardrive is not accepted, but correct in keychain
Last night in umounted my encrpyted external harddrive from my Macbook. This morning I reattached it back, and I was asked for my password, even that I have checked "Save password to keychain" which would automount it automatically, which worked fine for several months.....
So I tried entering it my password several times, but it was not accepted. I opend up the keychain management tool and you can unhide the password. The password I am entering is matching with that one stored in the keychain. I entered my password in a Terminal/Editor to see that for some funny reason the keymapping is wrong or something, and tried different USB ports for the hard drive. Nothing works..... So, what is happening here ?
MacBook Pro with Retina display, OS X Mavericks (10.9.1)
