Problem unlocking my Disk after upgrading to Yosemite

[Pcoder]

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 !!!!

This is just a longshot...Try reverting the HD from Core Logical Group to Mac journaled and then try accessing your vault drive.

The following post will tell you how. Takes less than 5 minutes.

-------> In 10.11 Disk Utility the Unlock button is hidden but can be restored:
