It's long winded - but if all else fails, there is an undocumented command
line switch for FDISK namely "FDISK /MBR" ...this corrects the MBR on drive
0 ...which would mean hooking your jukebox drive up to your PC as the
primary-master and booting from floppy/cd to execute the command.

There are any number of other utils to do the job - but there's nothing
like knowing you did it with the official bit of software!?

That all said, I do NOT get the feeling that this is your problem ...Joe's
advice seems good to me :)
