First my system: Q6600, EVGA 780i, 2x2gb OCZ ram, 8800gts 512mb, Adaptec 1220SA RAIDw/ 2x500gb seagates. I have lates motherboard and raid card bios, latest raid card drivers, and ran MEMTest overnight on mem. I start to install vista, and i can see teh drives, and create some partitions...So i create a 100gb one for the OS. here is what i have noticed: 1 - formatting 100gb in the vista installer takes about 10 sec. is this right? 2 - Copying files section of install takes about 3 sec. 3 - always hangs at "expanding files - 0%" except once it went to 60% without any changes of settings / hardware. 4 - Tried my retail disc, heavily tweaked vlite one, and mild tweaked vlite, all the same. 5 - I cant pre-integrate drivers as this is 64bit and i dont have a 64bit comp to create disc on.
