Hi,
Most probably disk was decrypted but it is RAW state. Did you have any problems with the disk during usage like bad sectors and/or did you run any defagmentation process while disk encrypted ?
Did your disk crashed ?
Can you check disk state from the Computer Management. Navigate to DIsk Management and check File System is it stated as RAW ?
Do you have any backup ?
I don't want to give you so much hope but you might not be able to get access to your date without formating and restoring data from backup
Try to do an exact bit by bit copy of the disk using for example CloneZilla or "dd" for Windows or "Windd"
http://www.msuiche.net/windd/
http://www.chrysocome.net/dd
http://clonezilla.org/downloads.php
On this copy try to:
- Slave the drive to another machine and run the following commands:
pgpwde --status --disk 1
pgpwde --list-users --disk 1
pgpwde --info --disk 1
- try to run
pgpwde --recover --disk 1 -p "passphrase here" to see if any users records can be found
