Hi there. Thank you for reaching out about this. I'm sorry to hear about what happened! Losing data is definitely never a fun time. We more than likely could recover deleted information. In the mean time, do not use that USB flash drive as it can overwrite the lost data and make it much more difficult to recover. The charge can vary depending on the difficulty of retrieving the data. We'll start with an estimate fee and then once we know we can do it, we give you the quote and you decide whether to proceed or not. To get started, please visit www.geeksquad.com/schedule to set up a free consultation at your local Best Buy.
