I own a Kingston thumb-stick. I have installed a Google Chrome OS image to it, so I could try it out. When it did so, it created 3 partitions (I backed everything up and the software that installed Chrome OS deleted my thumb-stick completely and created three partitions).
Now I want to get it back to one partition, but when I go to Disk Management, it will not let me "extend" the partition. I have tried different partitioning tools but they didn't recognize my thumb-stick anyway. I have also tried diskpart to no avail. Is there any software that will completely format my thumb-stick so I would only have one partition?
