Is it by anyway possible to make certain disk sectors read-only? (The disk being specifically a USB Flash drive). Also the possibility of repartitioning the drive and making one partition read-only would also be great.
You could give this utility a try: http://agnipulse.com/2011/11/partition-usb-flash-drive/
If that doesn't work you could look for a utility tailored to your make and model drive, but after a bit of research there doesn't seem to be anything special about yours. (Besides the partition removal software the company offers)
