I have been trying to use usb drives lately. One a usb 500 gb ssd drive for backing up and one a 64 gb micro sd card for use in an Android tablet, and I have borked both of them. Total value £36 so not a disaster. But I can't find a way to reformat them in spite of extensive googling and that is extremely annoying. There must be some way of forcing a basic format of these drives. Gparted won't touch them, msusb does nothing and various command line methods have done nothing. A lot of methods concentrate on getting data back but I don't want to do that. I just want them in a state to get data onto them. Any ideas anybody?Presumably when you attach the drive to a system, you get some additional output from "dmesg". It would be useful to know what that output was.George
When you say that gparted won't touch them, what are you doing with gparted, and what is the output of what you are attempting.
Once you know, from dmesg what device you're looking at (e.g. /dev/sdb) then you will probably have more success in addressing the device with a tool (personally I'd use fdisk, followed by one of the mkfs.* commands to create a filesystem on the disk. Also remember that you'd either need to run these with sudo, or be the root user, as they're low level commands that wouldn't be permitted to perform these tasks by an ordinary user.
We really need to have some concrete information about exactly what you tried and what the results were. So far we just have some vague anecdotal report about stuff not working. :-) Unless they're actually faulty you should be able to re-instate a new filesystem on them.
