Since you are doing a cold install, have you verified that it ISN'T a driver problem by attempting at least a partial install of XP, or another O/S? &nbsp; &nbsp;Since you have a single disk drive, why not disable the RAID mode to begin with? &nbsp; (Only reason not to is if you plan on mirroring the disk later on)<br />

good suggestion dlethe, thx.<br />
Drive is detected correctly by bios. ST380013AS, seagate barracuda 7200.7<br />
Installed known good drive (WD raptor) with XP installed, boots fine to XP.<br />
Run win7 setup from dvd same with known good drive (wd raptor), drive is detected.<br />
Installed new seagate 1.5TB drive, Win7 installing normally.<br />
seems strange, but older seagate drive must not be compat with precision 490 or win7.
