I have a Lenovo D20 and I want to reinstall Windows 7 but I can't seem to find the driver for the SAS controller. I have found an .exe on the Lenovo site but that won't help me much during OS install. Does anyone have any ideas short of copying the entire contents of C:\Windows\System32\drivers to my install USB stick? It's only about 80 MB. Can I be sure that the driver is even in that folder? It's a Marvell 64xx/63xx SAS controller for the record.
