I have an old HP NC6000 which I installed Windows 7 on. I can not get the SD card slot to work. At first it wouldn't see anything when I put a card in. After installing and un- installing several drivers from HP and Microsoft, now when I put a card in it shows up as being able to eject it If I want to. It does not show up in my computer as removable storage or any thing. I noticed in devise manager there is no SD host adapter listed. There is not even a heading for SD host adapter. The card works on my other laptop which is an NC6400. Do I need to install An SD host adapter?
