Don't use DataRetrieval.com for you data recovery needs. They will not retrieve any data, but will certainly take your expensive deposit.
They will also be careless with your computer and break it, but accept no responsibility. They will not apologize to you for destroying your hardware, and in fact will call you a liar.
They took my $322 deposit and then didn't deliver any results. They broke my computer and then told me that it was already broken. They are a terrible company that only want your deposit money.
They are total scam artists. Worst company ever
Monetary Loss: $322.
