I got a Kingston Data Traveller 2.0 USB Drive (512 MB). few days ago my frend borrowed it from me and now it has become unaccessable. I cant open it, cant format it. If i check its properties it says RAW File system, when i try to open it, it pompts that drive is not formatted and when i click on format now, it says drive cant be formatted Tried formatting it from Command Prompt but it gave me Error in IOCTL call error. any help ?
