Sounds very similar to a problem (squeaky HD with SPOD and long waits with certain apps) I had with with the original 30 gb Deathstar HD in my G4 dual 450 Gigabit Ethernet. It finally hung (squeaks & the spod) on Photoshop or Netscape and wouldn't boot. I was able to quit out from the original 9.0 disk and managed to swap all the data to a new 40 gb disk mounted internally as slave. After running Techtool Pro on the bad drive and finding corrupt directory files, I reformatted and have been using it for backup ever since with no problem, and the squeaks that had been freaking me out since day one are gone too.
