Ok, thanks. Bytecc ext sata hdd enclosure and separate adapter not working so good. Read about them and worried they don't work well. Any N56 users have luck with Vantec hdd enclosures? Thinking of trying one of those. Small text on laptop giving me a headache. Hope new glasses will help, but changing text size in windows, chrome and apps is clumsy. Before 14 days are up I am going to re-visit 17.3" asus laptops before settling in with this one.
