external microSD card.... went from 16GB and 32GB and FROZEN droid razr

[jp233]

Went downstairs to check on the data transfer. The Droid was dead, had shut itself off.

I'm done with this card. Will try with one more 32GB card, then I'm done completely and I'll live with my perfectly functioning 16GB card and I'll erase music to make room for pics and video.

Droids, but no problems.
I went from a Droid 2 to a Droid 4.
Had a 32GB Class 4 Sandisk in the Droid 2 and it worked fine.
Moved it to the Droid 4 when I got it and it worked fine.
Did the OTA upgrade to ICS and no problems.
I believe I formatted it once in the Droid 2.
