Due to a harddisk crash while travelling international, our support desk in the country I was travelling in, gratefully helped me to unlock my data and rebuilt my system on a new HDD. When coming home, my backup archive disk is not accepting the passphrase anymore when attached to the rebuilt machine. I encrypted the backup disk with a passphrase that reflects a key event in my personal life, so I am 150% sure I make no typo or have forgotten.
I now discovered, the foreign country support desk created the new system using "John.Doe" as the Windows 7 account name, while my previous Windows account was named "John.Doe@myCorp.com". Unfortunately my home country support team claim they are not educated enough on PGP to understand how to regain access or recover this 2nd, removable disk.
Should I rename my windows account back to the old name, or add it as an additional ID ? And what do I have to do with the encrypted boot disk not to screw up my running system ?
