    I really like the concept of the SanDisk Dual USB Drive.

    I have a 64GB Turbo and tried three different 64GB Dual drives. They are not recognized.

    I had to get a 32GB drive for a customer and got a 32GB Dual. It is recognized on my Turbo and my Maxx.

    Is there a 32GB limitation or is there something I need to do to support 64GB OTG drives?

    The 32GB drive is FAT32 and the 64GB drive must be reformatted to FAT32 in order to work in the Droid Turbo or Droid Maxx (the only two I tested).

    Since you can not reformat to FAT32 on Windows 7 you must use a third party program. Three are identified by SanDisk ...
    • HP USB Disk Format
    • miniAide FAT32 Formatter
    • Tware Fat32 Format
    After a reformat using HP USB Disk Format or miniAide FAT32 Formatter the drive is not recognized in either phone.

    After a reformat using 2Tware Fat32 Format the drive is recognized by both phones.

    So ... the solution is to reformat to FAT32 using 2Tware Fat32 Format.

    Interesting. I use a 64GB Kingston flash drive as OS storage with my M7 and never gave it any thought. Just works.

    I had no problem with a 64GB stick that was preformatted to FAT32 connected with a Motorola OTG cable. The only problem I had was with the SanDisk Dual USB Drive. It is preformatted exFAT and is not readable by the Turbo or Maxx. Two of the three third-party formatting programs I tried did not solve the problem.

    This was all news to SanDisk Technical Support also. (I really like having O-N-E 64GB memory stick in my pocket that can be plugged directly into a PC or Android phone.)
