ok did a bit of googling etc.
the
driver that my laptop is using was an 8.7 version of the
driver issue by dell for its customers I had downloaded a couple of months back, the same
driver works ok on this machine no delay in bootup (although no official windows 7 support). However the drive stays as just 'disk drive', if I load the intel matrix app it does correctly identify the drive.
I found a beta 8.9.4 driver (the official latest drive which hangs is 8.9.0) and that has the same issue as 8.9.0, it seems intel is writing bad
drivers for windows 7 in my experience as some may remember I had issues with their graphics windows 7
drivers as well. I would love to know if there is a solution to this as for now I am probably going to revert back to the microsoft ahci
drivers.
My research so far indicates it is possibly a compatability issue between my new WD 640gig cavalier and the intel matrix drivers.
So 8.7 no pause
8.8 not tried as cant find it anywhere I expect be same as 8.7
8.9.0 first driver to officially support windows 7 pause on 1st boot, 2nd boot does not finish
8.9.4 beta driver same behaviour as 8.9.0 but pause is a bit shorter
8.7 and 8.9.4 do not recognise the drive by its name in device manager, 8.9.0 did recognise it after some unresponsiveness in the OS but the reboot after did not finish.
