I bought this 32 GB plus another 16 GB. Key become inaccessible after some weeks. Important data for irrecoverable moment because unreadable key. All software used so far can not do anything. To access the contents of the key formatting is proposed so that data is the key. It is as if the key format is not recognized. I contacted the Kingston email support. Everything he has to say is go on the Internet to download software recovery or get close to a data recovery specialist (paid service) if not downloaded a formatting utulitaire "KillDisk" etc .. .. I put ZERO star
