A couple weeks ago my 128GB PNY Card said it was Corrupted and No matter how many times i Formatted it is was no longer usable in my Z Force or Any Device. I replaced my Corrupted Card with 128GB Sandisk and in about a week now it doesnt show up anymore. It says SD Card Missing. I took out the Card put it back in and nothing. I have Formatted my Cards as Internal Memory and understood they could not work in other Devices by simply taking them out. I fear my Z Force killed both Cards. IS there a Utility that anyone knows of that i can use to reformat these cards? Has anyone else had similar issues?
