The fix is suggested here: http://communities.intel.com/message/78539;jsessionid=48A13DE8B18CD478528559087E625352.node5COMS
The helpful message is from Polo127. Note that he installs then uninstalls the nVidia driver if its nnot already present.. I would never have guessed:
I ran into the same problem with my Asus nForce 650. There was another response from BorderShot with the solution. Here it is:
Alright, I got this to work by
changing the driver from the "NVIDIA
nForce Serial ATA Controller" to the
generic "Standard Dual Channel PCI IDE
Controller". In Vista, Control Panel
--> System --> Device Manager, IDE ATA/ATAPI Controllers, select "NVIDIA
nForce Serial ATA Controller", right
click, Properties, Driver, Update
Driver, Browse My Computer, Let me
pick from a list, and then select the
"Standard Dual Channel PCI IDE
Controller". After reboot, I was able
to use the SSD Toolbox.
I didnt have the Nvidia nForce serial
ata controller driver so i just
decided to update the standard duel
pci ide controller and rebooted
anyways BUT it did NOT help at all. SO
I went to nvidia's site to download
the lastest nForce driver which did
install the nforce serial controller
then I followed BorderShot's
instruction and it worked like a
charm! I am now able to see and TRIM
the drive.
Let me know if you have any
questions.
