R4 Clone Problem: disk errcode= -82

I've got a R4 SDHC Upgrade Revolution with an 8GB MicroSDHC from SanDisk.Some Games (also ones I've played before) don't work anymore. There always come this errcode.
I've tried it with formatting, another SDCard and several things. It doesn't help.Does anyone knows a solution for this?

i'm only guessing, but have you tried using a smaller MicroSD card?

Yeah, I have tried it with two MicroSD 2GB. It's still the same....

-Latest firmware?-what games?-Read the common issues thread?-Is the firmware in correctly?

you may be using the same R4 that i had, can you tell me your firmware that you are using?the card i had was, R4-III Upgrade Revolution
