Sorry but if you read the forum policies here we can't help you get around company policies.
Why not just use an external hard disk next time since that's allowed.
How can I make my thumbdrive appear on my computer as a hard drive instead of a removable drive? My external HD appears as a hard drive next to my C & D drives. Why you ask? Thumbdrives are not allowed to be connected at work, yet external hard drives are. I just use mine to transfer files, not download music etc. This policy is really inhibiting my work.
