Query: RealDrive Out of Business

I purchased the RealDrive 400 in December of 2006, in early August it just stopped working. I've tried to reach RealDrive, it has a one year warranty, but their phone number has a message that the voice mail is full and does not take messages. I've emailed them ten time, written letters to them, and an email and letter to Amazon....nothing....I finally got an email from a former distributor, and was told the company had gone under..............it's a great product when it works, but now I'm out of luck....do not waste your money.
