Hi
I have 40Gb laptop disk having 2partitions , initially both partitions were encrypted using PGP, now c drive is decrypted & is accessible , but for D drive it is not showing right MBR & file system so i cant decrypt it , is there any way to modify MBR to its working (NTFS) format?
Can we manually modify PGP encrypted disk so as one can decrypt them back?
Thanks

It is hard to answer you question
Usually PGP software writes special code into Boot Sector, so PGP driver can automatically recognize the partition
As far as I know there is nothing special in MBR

Hi Doomer thanks
It seems PGP uses a non-standard Windows bootloader called BootGuard which asks for decryption key. I am working on it & will post results.

Hi Friends
I have cloned crashed disk & the partition which is encrypted is showing raw file system , is there any way to convert it into NTFS by altering its signature?
Here is screenshot of disk.
Thanks

Hi Spildit
Thanks for detailed explanation. I tried to forcefully decrypt using PGP recovery CD , it tooks 13 hours & at the end PGP gave error Data Corrupted. It was a great learning experience.
Thanks & Regards

Could you not have used the boot sector back-up ?
