My G4 HD is dead forever?

[web_james]

Hi there,

I've been running OS 9.2.2 and OS X 10.1.5 for a wile.
The OS 9 was not so healty and in the last couple months OS 10 was also not so healty ( it didn't shut down).
So I decide to instal OS 10.2.1. At first glance everything was fine, but soon my OS 9 didn't start up on X, so I change the start up disk to OS 9 and made a restart to pass Norton Utilities. That was the last day my Mac have been seen alive. At that moment it start up on OS 9 or OS X. I try Norton. I try installing OS 9.2.2 again. I try installing OS X 10.2.1 agin, but the install wizard doesn't find my HD. It's like it's not formated!
I mounted the HD on a G4 Silver as a slave, but no luck; it wont detect.
I even try on a PC with MacDrive software...
I've got some information that I want to keep, so I do not want to format the disk. That's the big problem. Any ideas? Any similar problem?

Thank's
