Hancom Sheet is not able to write to my ext2-formatted 2GB SD card. It always says "This card is write protected. Please check lock switch".
THe same file can be written nicely onto the internal HDD.
Hancom Word is able to write to the card without a problem.

I have checked the permissions of the Sheet_Files directory: They are set correctly.

Anyone have an idea what could cause this?
Maybe this is a general problem with the Cresho / Tetsu SD driver and cards > 1GB? If not, any other idea?

Thank you
