Format is invalid error on hard drive

just loaded OS v 3.07 on my MPC 1000 and still have the same error message (format is invalid) whenever i try to format my brand new and functional (it's not a dud) Toshiba mk1032gax 100gb hard drive... what the hell is going on--i've been troubleshooting this thing for 4 months now--is it really worth it to pay 30 bucks to upgrade to OS v4, to see if it will make a difference, or should i just get a new hard drive. going nuts here.
thanks.

I did a quick search on google and it looks that this guy had the same problem from this website too. Here's what he said.

Mine doesn't work. Me p*ssed off right now.

I cannot format. After waiting like 2 minutes for the "hard disk" to appear in the format page, I press "do it" and nothing happens at all.

Anyone have similar issues with this drive.......

Here's the thread. http://www.mpc-forums.com/viewtopic.php?p=573318
It looks like he just decided to get another drive.

thanks for the help man... does anyone know if upgrading to jj os 4.76 would make any difference with this "format is invalid" error i get when i try to format my hard drive?

try to format on os 2.1

no luck on any os's--tried them all..except jj os 4.76. this **** sucks.

I'm having the same problem, is there no solution. I have a 40gb toshiba that was confirmed compatible but it says " Format is Invalid !! " when i try to format it. Please help.

Same problem here as well, Is there a solution? Searched this forum and it seems I'm not the only one but no one seems to be offering a solution?

Has anybody tried formatting it on a PC with an external USB case?

^gonna try it, I'll post my results.
