Windows 7: Files deleted before win 7 bitlocker encryption can they be recovered?

Files deleted before win 7 bitlocker encryption can they be recovered?

Hi everyone I am new to this forum. I have a question:
1. I had some confidential data stored on a partition that is not encrypted.
2. I decided to give away my computer to charity so I deleted this confidential data using a simple delete in Windows 7.
3. After that I formatted the whole hard disk and then turned on BitLocker and encrypted the whole drive and then gave away the PC to charity without using a disk wiper program .

My questions is: Is it possible for anybody to recover those deleted files using a data recovery program? I understand that when you do a simple file delete only the address of the data is deleted but not the data itself. If I encrypt the drive, files deleted before encryption do they get encrypted because they are not really deleted?

To answer your question.
I don't know because I have never tried.

Anything needing encryption, in my opinion needs to be removed when the hard drive is going to be use by another.

Kari has a tutorial I think will meet your needs.

I suspect your deleted files will soon be over-written. I doubt anyone buying from either Goodwill or Salvation Army will have the software and skills and desire to attempt any level of folder/file recovery.

I have no knowledge of what people using Goodwill or Salvation Army stores have for desires or knowledge. So if it was my drive I would wipe it or throw it away after destroying it.

I use Salvation Army Thrift Stores and I'm quite sure if I had the desire I would find the knowledge to get into the drive, if possible.

One never know who is shopping where.

LayBack Bear, you're right, however, the odds are still in the thread starter's favor; and since the computer has been donated already, the only solution I see: Either borrow it back and do a DBAN on the hard-drive, or, buy it back and do DBAN on HD and re-donate back.
