Query: I'm very disappointed with this drive

It stores, data, it's usb2.0, and it transfers quickly. Same as any other usb 2.0 flash disk.When I bought it I wasn't aware that Viking wouldn't include any management software with the drive. Which means there is no password protection. The drive is worthless without passwords because I can't store anything private/personal on it. I can't even keep Thunderbird Portable on it because then my e-mail is there for anyone to plainly read.I contacted Viking and received no response from them about how to resolve this, or if in the future they would offer password protection.
