ah... will this work? install vista as 'aha' mode. boot it up and run, go to device manager, update sata driver with the intel provided one, reboot to bios, switch sata mode, go.

Its a controller issue not a drive issue.
messing with a new clean good drive is irrelevant to this issue.
The fix is a registry mod to invoke the AHCI mode driver.
This afflicts both Vista and Win 7 systems.
see: Error message when you start a Windows 7 or Windows Vista-based computer after you change the SATA mode of the boot drive: "STOP 0x0000007B INACCESSABLE_BOOT_DEVICE"
score one for Team MS.
yep... quite a few controllers do not offer the AHCI mode, even on fairly recent vintage, and its not a given that the system maker [dell/hp/etc] accomodate the mode with appropriate BIOS integration [my daily driver HP DC7600 does not, for instance].
But if the controller has the enhancements, and if there is a well-written driver for it, and if the OEM supports in BIOS [all are the case with the Optiplex 755 in my lab], Win7/Vista apparently are incapable of permitting the original installation to 'default' to that mode.
Thus the registry hack.... err... modification.
yep solved, marked.
