Quick overview of ground zero: Home-built server/firewall/mail server/web server/MythTV back end/makes coffee. Motherboard: Abit IP35 Pro with Intel Core2Duo E6750 @ 2.66GHz eth0 --> cablemodem eth1 --> intranet 6 sata ports on motherboard (JBOD, not RAID) 1 sata drive for root 4 sata drives for MythTV recordings 1 sata DVD-RW I decided to add another 1TB drive for MythTV recordings, so I bought a WD Caviar Black sata drive. I plug it into the 6th and last sata port and power back up, and the server won't boot. Unplug the new drive, and it boots. I got an idea of trying to disconnect the DVD-RW drive and plug the new drive back into sata port 6, and the server boots. Spooky. So once again I unhook the new drive, plug in the DVD-RW drive again, and it boots. Then I discovered that eth1 was dark. No signal, lights aren't lighting up. So my server can get to the internet, but the rest of the house was SOL. I reboot, and then eth1 works, but eth0 is dark, so I can get to my server from my other computers, but nothing can get out to the internet. I reboot AGAIN and finally both ethernet jacks are live. I backed away slowly thinking clean thoughts. Again, this is several reboots with no changes to hardware getting different results. Current status is that the system is back up with all the original hard drives working, and both ethernet ports working, but my brand spankin new hard drive is staring at me longingly waiting to be deployed. I have a theory that my server is running out of "something" (interrupts? DMAs?), and the luck of the draw is determining what devices get what they need. I can't think of another scenario where devices would randomly work or not at boot, and adding a device disables others. What do you think? What can I look at? What can I try? Thanks in advance. Side note: I stick labels on all my drives with the install date. Apparently some of my MythTV drives have been spinning almost continuously since 2007. That is impressive. And scary.
