(Answer requested by Dennis Hayes) I think I can suggest a better approach; but first, to answer your question: You need a hub, not a reader. When you plug in a standard card reader — even one with multiple slots for different types of cards — the reader is assigned one address from the PC;…

Real-life measurements show ways to speed smartphone charging times
In response to “Is there any way to charge a phone faster?,” reader Peter Rothschild sent in the following interesting and very surprising post, based on his real-life measurements of smartphone charging times. Fascinating info about differences in USB charging cables! (Thanks, Peter!): “I have done a bit of experimenting with this on my last…
“Can I increase my RAM using a pen drive? Also, can I change the pen drive back after I am done?”
Not exactly. But if you’re using Windows, you can use a capable flash device to speed your system a different way: It’s called ReadyBoost, and it’s been built into the OS since the days of Vista. ReadyBoost lets your PC use a flash device as a predictive (“prefetch”) cache, preloading the data that the OS…
“Is there any way to charge a phone faster?”
Sure, turn it off! Seriously, your phone will charge fastest when it’s fully powered off and connected to an active charger. If a full power-off charge isn’t possible, power down as much you can. Some things you can do: Turn the screen brightness down to the lowest level you can use; use Dark Theme/Night Mode…
“How do I stop the CBS All Access app from lagging so much when I Chromecast it to my TV?”
Good luck. The CBS app is horrible! My wife has an iPhone with the Apple version of the CBS app; I’ve used the Android version of the app on two different, current Samsung phones; and have also used the CBS app built into my smart TV. On all platforms, the app’s native resolution is meh,…
“I know to de-fragment my HDD and not to de-fragment my SSD. Do I de-fragment my hybrid drive?”
It’s a quandary. Solid-state/hybrid drives (SSHDs) use a modest amount of high-speed memory as a kind of front end to a large, conventional, spinning-platter drive; software makes the two act as one. The idea is to yield a drive that’s faster than a conventional drive, but less expensive than an all-solid-state drive. But, as you…
“If you could only have a smartphone or a laptop for the next 5 years, which would you choose? Why?”
I’m glad I don’t have to choose! But if I did: I’d choose a high-end, state-of-the-art smartphone. Why? Because you can turn a high-end smartphone into a pretty capable notebook-equivalent by adding a USB- and Bluetooth-connected monitor, keyboard, and mouse. But while a smartphone can serve as a portable PC, the reverse isn’t true: For…
“Is it OK to leave a portable external hard disk plugged in and active 24/7?”
(Answer requested by Diego Gerardo Velasco) If the drive is simply on — fully powered up and spinning, even while it’s not needed — you’re wasting energy, and putting needless wear on the drive bearings. You’re also exposing the drive electronics to extra risk from electrical problems (spikes, surges, sags, etc.). If the drive is…
“How can I retrieve a copy of a document from the hard drive in the office copy machine?”
Not all copiers have hard drives (it’s generally only higher-volume copiers that need to queue, track, and manage numerous large print jobs); and not all copiers with hard drives work the same way. But, in very broad terms, and depending on whether you’re trying to do something above-board or not, here are two approaches: If…
“If you could only do one computer upgrade when you purchase a new computer, would you upgrade RAM, processor, or storage?”
(Answer requested by Mandi Bailey) If it’s a brand-new PC, odds are it’ll have a reasonably current, capable CPU; and an at least acceptable hard drive. But most PC baseline models have only a modest — sometimes minimal — amount of RAM. So, if I’m allowed only one upgrade, I’d go for more RAM —…
