when i read all of the comment, most of them got the same problem and why dont u justtell us the solution so everybody and be happy about it. . . all i need is a solution to this which works 100%. . . so what is the solution?
Don't you think that if anyone (including SanDisk personel) knew a solution that they would post it here?
In other words, there is no known solution other than returning it as defective to SanDisk and getting a replacement.
