Hi,<br><br>I posted a while back on my iMac drive having problems. I have now determined it to be the actual internal Apple disc drive that is acting up. I've heard this type of drive has a tendancy of acting up. I've looked for new firmware updates, but have found none. It's an old Rev. D 333 and it's still trucking along but for this. It all happened after the Jag update. (and the 10.2.1 update too)<br><br>Anyway, any thoughts would be helpful. <br><br>thanks!<br><br><br>AlgæS
