Back up then Swap Internal Hard Drive

[wuulfgar]

I wonder if this is my problem with Call of Duty 2 and Quake 4. I had an internal 160GB drive in my Powermac G5 dual 2.0GHz. I installed a new SATA2 250GB drive (which down rates to 1.5Gbs/s throughput) and partitioned 100GB for 10.4.11 and 132GB for Leopard (Real Soon Now). I duped my existing install to the new 100GB partition but had it named something different from the original volume. I booted to the new cloned install and everything seemed to be working (famous last words) so I wiped the 160GB drive to make it a data drive visible to both 10.4.11 and Leopard. So far Call of Duty 2 and Quake 4 fail to run but most other apps I've tried so far work. I've even tried installing Call of Duty 2 all over again and it refuses to run, complaining that it can't find the data folder. I've renamed the new 100GB partition to the same name the 160GB had. I've rebooted. I've tried CoD2 fresh and after installing the 1.3 patch both on the current boot volume and on the data volume. No go. Always the "could not locate data folder" error even though the data folder is clearly right there and the game CD is in the optical drive. Quake 4 just flat out fails to start, crapping out while trying to load the game. Like I said, other apps are working fine and keychain is fine and everything else is fine. Any thoughts?
