Well as tried I have found out that the loose IDE cable must of been the cause to Leopard KPing. After reseating the IDE cable on the ATA100 bus I booted leopard last night and ran it all night long... No KP. Woke up this morning and put the computer to sleep. Woke it up now to test it STILL no KPs or lockups however now the 2 HDDs on the ATA66 bus have disconnected (as if unplugging a USB Stick without ejecting it 1st). What is the cause of this?
