I'm running Entourage 2004 on OS X 10.3.9 (iMac G3, for at least a few more weeks). I've never had problems with Entourage until we had a brief power-out the other day. Since I restarted, Entourage won't open. It says the database is corrupted, and I need to rebuild it. But I can't rebuild it -- the Entourage Database runs into an error almost as soon as it starts, and says it has an I/O error with a bad block. However, Apple's Disk Utility and Hardware Test both say everything's fine. Anyone have any clues what to do next? Is it believable that Microsoft would find a bad block that Apple can't?
