camera problem which sd card

I use a 32 gig class 4 card with no issues....Sandisk is the manufacturer.

 

I had a Patriot Class 10 32 gb that couldn't go more than an hour after restarting or unmounting and remounting the card without having the pictures not save.

Now have a SanDisk Class 4 32 gb that had been fine for about 30 days and then last week started having the same problems.

Just wish Motorola would get their act together and fix this problem. I can't wait until ICS comes out to fix this.

 

I am pretty sure this phone has issues with class 10 cards because I also have this same exact issue but when I put in something with a lower class I can go months without having this issue.
