Rebuilding the Internal NAND Flash Memory
Rebuilding the Internal NAND Flash Memory
It is unlikely but possible for the Internal NAND Flash Memory to become corrupted such that
normal hard reset and software update procedures fail. In particular, if the LCD displays the
following:
Internal File System Error. Low-level fmt error.
and recurs even
after a power cycle, the internal
fl
ash memory
fi
le system is probably corrupted.
The following procedure can be used to rebuild the Internal NAND Flash Memory using either
an xD card or the USB port via computer. Before starting you will need a special utility program
called PC3FT040.BIN or a later version (last 3 digits are a higher number). This program may be
downloaded from the kurzweilmusicsystems.com website. This program can reformat the
internal
fl
ash memory then copy needed system
fi
les to it. The Diagnostics
fi
le can also be
downloaded from the website.
