Yes as of yesterday morning the card was formatted within the unit as FAT32. Still experiencing the issue. One thing I found interesting is that the regular Windows Format only allows NTFS or exFAT format so I had to use the HP USB Disk Format Tool which allows FAT32. This happened both with the card inside the included USB adapter as well as in the X5 unit but worth noting nonetheless.
HD Tune error checking underway on the card. Too early to tell as the scan is only at 6/64GB currently. Fiio has been contacted.
