Switch your slimline drive between master and slave

English German   Print

NEC's slimline drives are configured for either master or slave IDE mode. In order to change this, you need to exchange the drive's bootcode. For some drives NEC offers a DOS based tool for switching your drive from master to slave.

There was no solution if you were unfamiliar with DOS or could not access the drive from DOS at all. For some drives there wasn't even an official way to get your drive back from slave to master again. Do not change your drive's bootcode if you don't really have to, as this may make a perfectly working drive inaccessible.

Some people could successfully help themselves by soldering pins 45 and 47 on the IDE connector. But this is not a universal way for everyone.

We can currently offer bootcode flasher software for NEC ND-6500A, ND-6650A, ND-6750A, ND-7550A and ND-7551A slimline drives.

Although changing the bootcode in your laptop might work, it is highly recommended to use an IDE adapter and a desktop PC for this procedure. In order to assure that broken versions of this software cannot cause any further damage, you will have to authenticate each time you want to change the bootcode of your drive.

Be sure to follow the instructions when using this program and only download these files from our site, because this is the only way for us to ensure that you are always using the latest version. We will not support downloads from other sites.

Please note that after changing the bootcode of your drive, you will have to reboot your PC and flash a regular firmware which matches your drive's IDE configuration.
