ScanDisk ssd u100 256 stuck

Hello I’ve got a problem. I have an Asus ux31 with a ScanDisk u100 256. There are 3 partitions but they can not be edited. If I try to remove the partitions then the software says that it succeeded but they are still there. Formatting the same thing. Get the report succeeded but the partitions are still unformatted. I do not know what to do. Can someone help me?
