HP 9420 DRIVERS WINDOWS 7 UPDATE

Take WEI scores with a grain of salt - run actual HD benchmark programs to determine if your subsystem is running the way it is supposed to. I'm hoping post-7000 builds aren't so punishing on normal hard drives because people instantly assume their disk subsystem has something wrong with it. Is there something I'm missing? Why does this problem surface on Win7 and not on Vista? Thanks in advance! Keep in mind the disk scores have been refactored for SSD technology and the W7 scores are much 'lower' for normal hard drives compared to Vista. Also I scoured the hp.com support pages to find Vista drivers for this, but no avail.

So I suspect that the missing driver is the former - but searching Windows Update results in nothing. So I went to invesigate in Device Manager, and found two unknown devices 'Mass Storage Controller' and 'PCI Simple Communications Controller'. On Vista this same computer scores 5,2 - although that HD is a 7200 rpm drive and some what faster, 2,0 seemed extremely low. I was therefore stumped to see the Experience Index score a low 2,0 due to a slow hard disk! It's worked like a charm, and since I've read about Windows 7 having the same drivers as Vista, I didn't think I'd experience any problems, driver-wise. I usually run Vista Enterprise SP1 ењ†4 on the main hard drive. I've installed public beta (build 7000) ењ†4 on my trusty old laptop, on a spare disk. They are now listed under other devices as an unknown device. However there wre two unknown drivers under it which did not clear. That driver cleared the pci simple communications controller.
