A second physical storage area, including sectors x+1−y, usb protect is preferably mapped to a second virtual LUN (virtual LUN2) corresponding to the secure section 120.

These tiny USB flash drives are hard to care of. I lost my USB flash drive in my office, which was stuffed with some confidential information of my employer. My boss found that USB drive and plugged into his computer, but, he could not open it as I was using this amazing software. My boss called me and appreciated my approach towards data security. It was a proud moment for me, thanks to usb lock, otherwise, my job might have been at risk.
