I recently encrypted a drive by accident when i was fooling with the cipher tool at home , the problem is i didnt realise I had encrypted the whole drive ( plz dont rub it in)
anyway to cut a long story short i rebuilt the system n as a result am unable to axs any data on the d drive , it registers as a healthy volume in disk manager but no file system is listed (no NTFS listing next to it)
and when i click on it in the logical drives veiw it says i have no permissions to axs , and when i try and add permissions it says i dont have permissions to add permissions.... Is there anyway I can retreive the data off there ???? there is like 14gig of data on that drive including my CV & all my study materials along with 2 years of email backups, my docs backups ect & god knows what else... and I am really desparate to find a solution for this stupid situation i have got myself into

( BTW Im guessing on the EFS bit but thats the only thing it could be , also it gets listed as Landis Secure File System when i try n look at it with partition magic ( no PM cant recover it i tried that first)...
recovery console is no help either it says its 1 or more unrecoverable errors...

Thanx In Advance

mrwolf, I'm afraid I have bad news for you
format the drive is all you can do. Once you rebuilt the system, that killed it. the administrator is the emergency encryption restore agent. If you had logged on as the administrator, then you would have been able to recover, but since you rebuilt the system, the administrator now has a different SID, and will not be able to recover the data.sorry
I am assuming you did not backup the private key?

grrr its as i thought , oh well wheres my sledge hammer err i mean my copy of fdisk ;)
I kinda had a sick feeling in my gut when I realised what I had done ( no more tinkering after i get home from a night out on the town)and had a feeling that was the outcome . Just out of interest if the workstation had been a member of the domain I run at home , would the domain box have kept a copy of a usable recovery key ????( it wasnt a member so it does not matter but it was a point I was mulling over)
 Unfortunatley I dont exersize proper DR on that workstation ,as normally its my gaming box .... but in light of this event I think I will add it to the backup schedule in future & dust the cobwebs off my wallet and go buy some more tapes

Only if the user was a memeber of the domain, and had been issued a key, and had backed it up, how ever the domain admin would have been the emergency recovery agent.
again, if you hadn't rebuilt the system, then the administrator would have been able to help, but since you rebuilt it......
