Simply put, I now have 59.48 GB of extra storage space in my Samsung SGH-1717.  I did not think it was possible because Samsung recommends using a 32GB microsd on this phone.  I tried to re-format this card using my phone just like what the other reviewers mentioned, but, it didn't work.  My phone kept recognizing the microsd card as blank.  However, after using EaseUS Partition Master Home Edition that I downloaded on my PC (yeah, it's free) to convert to FAT32 , it finally worked!
