A mensagem útil é de Polo127. Note que ele instala e desinstala o driver da nVidia se o nnot já estiver presente .. Eu nunca teria imaginado:
Eu tive o mesmo problema com o meu Asus nForce 650. Houve outra resposta do BorderShot com a solução. Aqui está:
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.
