SD card 8GB format problem

Recommended Posts


Have had no problems with 4GB SD's using SD.lib. But when I started to use  8GB SD's get all sorts of corrupted files.

Not too sure if I have to reformat them (the 4GB just plug in and work) or I have a bad batch from China, or 8GB not supported by SD lib.

Any ideas.

I think there is some kind of limit. I found anything over 4gb got pretty funky. I tried a few different cards and they all misbehaved. I know the cards are good as they all work fine in my dslr camera.


I'm not using sd.lib but rather petitfs.


Same problem though.


I found some 4gb cards on sale and bought a handful.
