Sandisk stuff generally seems to work, and most all my current USB sticks are Sandisk Ultra Fit (the really tiny ones, typically in 16GB or 32GB). -- john r pierce, recycling bits in santa cruz

I was using a 128GB USB 3.0 drive. I tried a lowly 8GB drive and it worked. Thanks, Mike

I'd love to hear how's CentOS 7 support for E7470 hardware.Hi Milos, The Thinkpad T series and Latitude are *very* similar computers. They are both business "ultrabooks" with a 1600x1080 display option, nice keyboards (not "chicklet" style), a trackpoint and trackpad and RJ-45 builtin. I bought a Dell Latitude E7470 over the Lenovo for several reasons. One is this comment which is worth mentioning again: On Fri, Sep 30, 2016 at 11:58 PM, Gordon Messmer <gordon.messmer at gmail.com> wrote:> It's worth mentioning again that Dell is one of the companies doing the > development for the bits that don't work, and that those drivers are often > the ones that get Lenovo equipment going, too. Lenovo does not, to the best > of my knowledge, do any Linux development.Another reason is that I have heard about people having problems with Lenovo. Not just with software but with hardware malfunctions. I spoke to someone on the phone that had hardware problems with their new Thinkpad (although I suspect some of the problems could have been misdiagnosis by the user). After describing how nice the E7470 they're thinking about dumping their 1yo X250 and getting a Dell. As for the Carbon, that is a very different computer. The Carbon is an ultralight / thin Macbook-like machine with Windows so I have no advice for you there. I have not tried CentOS on the E7470 but I'm quite certain it would not work because I have tried the latest Fedora Live which is about 100 kernel revisions newer and even that doesn't completely work. Specifically, if I plug in an external display it freezes. My feeling is I need a newer display driver (and thus newer kernel). The only other issue I noticed was that wireless didn't work but it seems more like a glue issue and not necessarily a driver. Otherwise, suspend and everything else worked near as I can tell which is actually pretty impressive for a brand new machine. So, I am doing other things while this new E7470 ages like a fine wine. Or maybe I'll loose patience and just install Fedora and try a "vanilla" kernel package. Then maybe after a year or two CentOS 8 or whatever will run on it and then I can just run steady for 4+ years without getting pummeled by stupid updates and feature creep that you get with Fedora and Ubuntu or whatever the latest hot distro is. The E7470 is obviously a laptop of choice for business people. And that is the type of machine developers use. So chances of good compatibility are very high. You just have to give it time. I was watching Daredevil season 1 and they use Latitudes that look exactly like mine. And that was probably filmed in 2014. So the form factor at least has been around for a while which is good. Unfortunately I can't say the same thing about the show. Mike
