Wow, that's a pretty hefty temperature. I've rerouted cables specifically to improve airflow, and the old ATA cables are no longer in the case. However, you point is well taken. I have an indication from this client that the system was left on all night last night. Hmmmm. If Apple System Profiler can't see them, how can I get DiskWarrior to see them? I'm having a brain freeze here. Thanks.

Disk Warrior will probably find a bad volume wrapper. Have they checked the heat in the case with those drives running? My MDD 867 would never handle more than two drives without a meltdown. I have two drives in the stock ATA 100 and emptied cages and ribbons from ata 66 location to reduce heat. With two optical dives I get up to 144 deg F just using a web browser.

Of course, Disk Utility doesn't see them either. ---------- G4ist, a listserv for discussion of everything G4. FAQ at <http://www.themacintoshguy.com/lists/G4.html>.
