[QUOTE="Andy Ful, post: 566896, member: 32260"] I read somwhere that it is possible to find the factory software by the chip number, that can format disfunctional pendrive (if GParted fails). Here are more details: "If for no reason you encounter "The disk is write-protected. Remove the write-protection or use another disk." – message for your flash drive it is more likely than not that this is due to the failure of controller’s firmware. In this case you need to flash it by using recovery utility suitable for controller of your USB flash drive. Read above how to find correct utility for your flash drive knowing its VID and PID" "First, recover the functionality of the flash drive’s controller. To do this find utility to work with it. If you know both the controller model and the name of the flash drive manufacture then a suitable tool can be found on the manufacturer's website or somewhere else on the Web.
