Troubleshooting & Maintenance
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.
Rebuilding with an xD Card
Warning : Rebuilding the Internal NAND Flash Memory also does a hard reset erasing all user
created fi les and restores the unit to factory settings.
The following assumes that you are familiar with the procedures to enter the Boot Loader and
perform normal system updates using an xD Card or the USB port via computer.
1. 1. Using an xD card reader/writer, copy these four fi les to an xD card:
