It will be slower but safer to put the card in the phone first. 64GB cards need special formatting and it would be a good idea to make sure the phone is happy with the empty card and then to let it do all the accessing. Just make sure you properly seat the card. It has to CLICK into place in the phone before you insert the cover/SIM holder. Either use the special tool that comes with the phone (the back is a flat surface that's designed to help you seat the card) or a fingernail, but make sure the card is fully seated. Otherwise it will fry.=========================================================================================================
Before I put this card in my phone should I transfer my files over using my reader,or put card in phone then move files over.
Thank's

Motorola says they support up to 32GB. Some people report that 64GB works for them but, as I said earlier, there are formatting issues because the FAT32 format can't be used beyond 32GB.used all of my sd cards 16,4,and 32 and they all work with my phone,I think I got bad information when guys were saying 64gb worked unless I bought the wrong card.
I bought a 64gb microSDXC should this work in my RAZRMAXX HD
If the phone will recognize the card at all and allow you to format it, that's the way to go for sure.I had problems with my 64 GB card, until I reformatted the card with the phone. Which meant wiping out all the data I had put on it and then loading it up again.
So far it has worked well. I have about 37 GB filled up, video and music mostly
