Here is my situation... I believe I had bad sectors on my drive, and while halfway through reformatting, it crashed... So now, when I boot to the HD, I get the prompt to insert the 2nd Install CD, but it never finishes (because it hits a bad sector). So I want to write Zeros to the drive. and thus I pop in the Tiger install disc... With the Tiger install disc in my drive, I boot to it, but it gets to the blue screen and locks up. So I can't finish the install with the original discs, I can't write zeros using a Tiger disc. Any ideas? I was trying to reformat it using commands in Single-user mode, but my bashing needs some work It is a 1.67Ghz Powerbook G4. Thanks in advance!
