I need to remove the "write protection" on my 64GB USB storage disk. I have too much to lose and all my backups for my profile are on here. I cannot write to it OR download from it. There is not a mechanical up or down flip switch. How it got write protected is beyond me. I only noticed this because my user profile became corrupted and I wanted to reinstall the programs from my USB drive back onto my profile. It says it is write protected and to remove it or use another disk. I don't have another disk. I'm using Windows XP Pro, Service Pack 3 on an E machine 3.33 GHz.
