Can't access encrypted hardrive anymore.

[MacNoob444]

I worked fine yesterday but today I can't get access to it. When I enter the password it just stands still and does nothing for about one minute(i took time) sometimes more, then the window with password shakes to indicate that is a wrong password. If i press "Unlock" again it shakes in a second. When I enter the wrong password intentionally it takes no more than a second for the window to shake. During this minute long time I can't use the computer normally either. I can scroll in chrome, but I have to dubble click all the links to use them, I can't write anything and I cant open any other program on the computer.

Mavericks 10.9.4 and a Seagate Plus Backup Portable Drive btw.

I've tried the disk utility Verify disk and it says it needs to be repaired, so I try to repair it but then it ask for the password. I enter the password and it "freezes" as described above, so I can't seem to do anything. Any idea how to fix this and not erase the whole disk?

From disk utility: Verify

Nope. Sounds like you will need to erase and start over.

I wonder if DiskWarrior could resolve that issue.

Will it work with FV2 turned on? Sure worth a try though.

According to Alsoft the makers of DiskWarrior:

If you plan to rebuild a disk that is encrypted with FileVault 2, you'll need to run DiskWarrior while started from OS X 10.7 through 10.10. Alternatively, you can decrypt the disk and then run DiskWarrior.

Which gives me the impression that it would not help out in this particular situation.
