Overview on the used writing strategies

Do NOT try to crossflash between 2.** and 4.** firmwares by using Binflash. This is very likely to DAMAGE your drive or make it INACCESSIBLE!

If you need to exchange master to slave on your NEC ND6500A drive, you should try the NEC Bootcode flasher. There is a NEC ND6500A Master bootcode flasher and a NEC ND6500A Slave bootcode flasher

If you prefer the original DOS software from NEC, please use the NEC ND6500A Reverse ATA firmware package but be sure to follow the instructions:

  • It it highly recommended to use a slimline to IDE adapter and a desktop PC for this procedure instead of leaving the drive in your notebook. You might be unable to complete this procedure if the drive is still installed in your laptop. The drive has to be attached to the secondary IDE channel, you will probably get an error message on the primary channel.
  • Boot into plain DOS. A command prompt from within Windows does NOT work.
  • Execute the file 6500BOOT.BAT
  • Reboot your PC. The drive should now be recognized as a slave device
  • Execute the file 6500MAIN.BAT to flash the main firmware

If you want to revert your drive with a flasher made by NEC from slave back to master again, you can do so by using the NEC ND6500A Normal ATA firmware package and following the instructions above - you just have to exchange master with slave and vice versa.
