Hi i have the aao a110l and I am grateful for this forum which helped me a lot in the past 2 weeks. Now it seams reading is not sufficient for my problem, so I have to post. I changed the "l" to "x" by installing XP. Well, after that and tweaking the SSD I was quite satisfied with the overall performance of my one. But unfortunately I had to reinstall XP and now "disk write caching" is grayed out. I am somewhat confused... Can anyone help and tell me how to fix that? all the best
