It sounds like it could be a poorly seated or possibly faulty SD card. If you want to try replacing the card to see if that puts a stop to the issue, any micro SD over 500mb should work. (I think we use 1GB). To access the card you'll have to remove the end cap on the left hand side with a hex driver. We also recommend formatting the new card using the tool available at this link:

Once it's formatted insert the card and boot it on up. Try saving a couple presets and see if you get the same errors.
