Tale of woe about 64gb MicroSD cards.

 

I love these things and have five of them but they don’t seem to take repeated formatting very well.  After being satisfied with my first three I bought two more from Best Buy.  Neither of them worked and Best Buy exchanged them.

One of them worked okay until I formatted it for the third or fourth time, then it failed.  The other didn’t work at all.

 

I contacted SanDisk and got one of them replaced.  It worked.

Then SanDisk replaced the second.  It too worked.

 

I cannot now tell which card is which, but I the other day I reformatted one a couple of times and it stopped taking a format.   Every time I tried it seemed to get worse.  After a couple of failures I tried other formats than exFAT , with no luck.  I tried another formatting tool which usually works but it too failed.

 

OK, I’ll bite. What’s with all the formatting? This should be a rare occurance, a last resort, a once in a great while sort of thing. Not an daily or hourly ritual. 

What you’re doing sounds akin to tearing down and rebuildiing your car’s engine every weekend, just so it’s fresh for the next week’s commute.
