My older Sandisk extreme Pro has the firmware 6EA 1010. In crystaldiskinfo shows with the newer USB stick a lifetime of 0%. No data on power-on and read-write operations are displayed. Here is a link with the same problem: http://forums.sandisk.com/t5/All-SanDisk-USB-Flash-Drives/SanDisk-Extreme-PRO-USB-Flash-Drive-6EB-1030-witch-SMART-failure / Mp / 356542 Is the stick broken?
