Without changing where /sda was connected, I then connected the other 4 drives for the RAID5 array, and suddently the system wouldn't boot - because the 80 gb drive was no longer the boot drive, and I had to reset bios to make it that way, AND, my OS drive was suddenly /sdd !!!

Yes David I felt you hadda be feeling that way. I agree with your
learning and I am learning with you. I recently upgraded both my boxes
on my little network and I bought 4 - 200G SATA HDs with the intention
of setting up a Raid 5 but in reading all the specs tips forums etc I
bogged down and decided I was getting in way over my head if things went
S. I decided not to go RAID and I am just keeping a manual backup
duplication but I do intend to automate it. I have a 3rd box that I am
gonna add on also and keep all 3 synced at some point.... maybe that is
... lol Linux is so amazing but quite daunting for a non-programmer
Break a leg with your recovery man you deserve to win this one.
