I bought this card on the strength of the 64GB XDSC SanDisk in my phone right now.  It was a gift for a friend of mine and sadly it corrupted within minutes of first use.Initially it worked fine, then dead.  We checked in a laptop and Windows Disk Management screen told me it had a single 128K partition and the rest was unusable.  Outstanding.The replacement sent by Amazon (Thank you Amazon, you are always excellent) is sitting in my office right now, I should probably check it out.
