Title seems improbable, but is it possible to view, copy, or otherwise modify files on a filevault 2 protected thumbdrive created in lion on snow leopard?


Long story:


My Seagate Momentus got trashed recently, so I'm going out to get a replacement tomorrow. That drive was updated to Lion 10.7.4. I am typing from a Snow Leopard 10.6.8 HDD. I actually need that data on the new HDD, so I was thinking of getting one of those USB-SATA adapters. (The macbook won't boot off that drive, won't detect other drives... Swapping internal drives is tedious and it won't boot from the trashed one [duh]). But there's a 50% chance that the important data is on the thumbdrive, so I don't want to waste the money on an adapter.


So here's the problem: Is there a way, external program or not, to read that data from the disk? I know the password, but I am not willing to risk modifying this splendid backup HDD with a fully working system on it by installing Lion.


I tried mounting it, obviously it doesn't work. DU tells me it's an "incompatible format".


Tl;DR: Can I read a Filevault 2 partition from snow leopard?

    I have a strange issue with mine. I was making backups to my encripted filevault 2 drive from two different mashine, Mountain Lion and Snow Leopard. Was working fine. My Snow Leopard machine hard drive gone down. Installed Snow Leopard back on my machine, updated it, but I can't access my backup disk as it is "Incompatible format".


    How I was able to make backups using Snow Leopard on FileVault 2 encripted drive, but now I can't access it after reisntall? Doesn't make sense to me at this point.
