    Yesterday I upgraded to Yosemite I have microSD disk encrypted with "Encrypted Logical Partition" from Finder. After upgrading Mavericks to Yosemite when I insert the microSD and asking me for the partition password which I am sure It is correct it shakes with no!
    I tried to fix the permissions with command line and then to unlock my disk from command line it ended up with this message :

    -69749: Unable to unlock the Core Storage volume
    I checked and repaired the disk from disk utilities and a green message came with everything is OK.

    I unplugged it and plugged it again asking for unlock password I am sure it is correct and I wrote it physically on a paper and used it many many time on Mavericks but it shakes with incorrect passwort after upgrading to Yosemite !!!!
