Spinning Wheel - Macintosh HD 1

G4 MDD, OS10.4

Just recovering from a Pram battery change and my main drive won't boot past the grey apple. Disk Utility is telling me the drive needs no repair and I can access everything on the drive. When I boot holding option the drive comes up with the number 1 at the end of it's name and I have a very vague memory that this causes the drive to be locked in a loop it can never escape, but all you need to do is remove the '1' from somewhere in a file in it's boot block?

Does anyone know this trick? Wish I'd bookmarked it

You change the PRAM battery , it might loose the name of you're start up disk .
Try to reset you're PRAM , holding down P and R key during start up

Thanks for replying dobby, I've reset the Pram and open firmware, I just wish I could remember the address of the site I discovered the tip I mentioned. Just thought someone here might know it
