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 flash memory file 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 flash memory then copy needed system files to it. The Diagnostics file 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 files 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 files to an xD card:
• File Transfer utility, PC3FT040.BIN or higher
• PC3 Operating System file, PC3OS111.BIN or higher
• PC3 Diagnostics file, PC3DG018 or higher
• PC3 Objects file, PC3OB111.PC3 or higher
2. Turn on the PC3x and enter the Boot Loader. Then insert the xD card into the slot on the
PC3x.
3. Press the File Utilities soft button.

briefly then another menu.
