I had this Sandisk 32Gb Class 10 micro SDHC card in a Pittasoft Blackvue DR500GW-HD in-car camera DVR. It worked like a champ for 2 months and then died with the dreaded "Please format the SD card" errors. Stuck it in my Mac Mini (2011) and it is unrecognizable. Same with Windows PC. Even the low level HP SD card formatter cannot reformat it. So in the garbage it goes. I have 2 more of these cards in my Garmin GPS devices and they continue to work (so far) but they are not being written to continually every day like the Blackvue. So a word of advice; if you need to write to these cards often - buy something else.
