Eh, I bought this USB flash drive 1 day ago to make a bootable USB flash drive for Ubuntu. After writing the iso a couple of times, I still can't boot the USB flash drive (maybe UEFI problem) but now this USB flash drive has problem itself.
When I connect, it says 'you need to format it...' but I can't format it, it shows error. I tried PartitionGuru tool and even that tool crashed and couldn't format it.
So my USB flash drive done :( ?
EDIT: It was a Kingston 8 GB USB flash drive but now it shows only 8 MB
