If I cannot recover your data, you don’t pay anything.
If I can recover your data, $50 charge for it and I give you a download link if the data is not sensitive, or a thumb drive if your data is sensitive. I make some quick attempts and may be able to recommend something.
The next option would be a laboratory. I can diagnose and try to give you some idea of your chances if you send your media to a laboratory.
If your data is worth $500+, I recommend Data Recovery Labs. They have a “no data, no charge” guarantee.
Last resort, I can open the drive and make an attempt. Opening a hard drive does not usually cause damage that would prevent a laboratory from recovering data if you decide to send it, but it can increase the recovery cost and the laboratory will know if the drive has been opened.
