“Can I still make use of a hard disk drive that is at 0% health?”

Sure. You can also start your day with 0% charge in your phone; or leave on driving vacation with 0% fuel in the tank; or start a scuba dive with gauges showing 0% air…. There are many things you can do. It might even work for a while. A “0%” phone usually has at least…

“My PC needs repair and will be reformatted. Should I just save my files and programs, or should I clone my entire hard drive?”

The silver lining, when you have to reformat a PC, is that it’s chance to start over with a 100% clean rebuild — to set up everything afresh in a like-new, pristine setup. For that, a simple “files and data” backup can suffice: After the repair, reinstall the OS from your official setup/install medium, add…

“Are there USB pen drives that can hold as much data as external hard drives?”

(Answer requested by Pavlov Pascale) Sure. If you have deep enough pockets, you can even buy USB pen drives up to a full 2TB — that’s TB, not GB — in size. Two terabytes is huge capacity in a pen drive, but the price is likewise outsized — something like $1000/TB, or roughly 10x more…

“Is a 32GB SSD on a netbook enough to run Windows and Microsoft Office?”

In a word: No. On this page, Microsoft states (emphasis added): “Starting with the May 2019 Update, the system requirements for hard drive size for clean installs of Windows 10 as well as new PCs changed to a minimum of 32GB.“ That’s Windows itself. MS Office also needs room, although the space requirements vary by type…

“HDMI ports are usually output only, so how can I use my Win8.1 laptop as an input display screen (preferably free)?”

It depends what you want to use as the HD source. If the source is another PC or similar device (smartphone, tablet, laptop…), you can likely use any remote desktop, screen sharing, Twitch-type screen-streaming, or any similar type of app (that both devices support) to display whatever’s on the source screen on your Win8.1 PC’s…

“How is it done to format multiple PCs (same model) at the same time? Does a disk cloner work? Does it handle everything — drivers? BIOS?”

Your question touches on two separate things. First, yes: Cloning can perfectly replicate everything that’s on a PC’s disk. If the PCs are truly identical (as in a managed corporate setting), and the OS is licensed for it, then you only need one Master disk image, which can then be deployed/installed more or less simultaneously…

“Is Windows 10 Pro worth the $200? What are the advantages over the Home version?”

I think the only place it still costs that much is at the undiscounted Microsoft Store. With just a little shopping, you’ll find prices half that; and only a small or nonexistent price differential between Home and Pro. (In fact, checking prices today to write this piece, I see Amazon is selling Win10 Pro for…

“Why are external hard drives so big when the iPhone can fit 512GB along with other components in a thin package?”

A classic hard drive is a complex mechanical assemblage consisting of a circuit board, one or more spinning platters, a spindle, a hub, bearings, several read/write heads on actuating arms, at least two electric motors, and miscellaneous wiring, connectors, and other parts. (Examples.) In contrast, a SATA SSD contains just air and a circuit board….

“Can I clone an encrypted hard drive?”

(Answer requested by Anthony Dimpu) Sure. In general, drive cloning basically just hoovers up the ones and zeros from a source disk; and lays them down, unchanged and unexamined, in an exactly analogous pattern on another disk. It doesn’t matter to the cloning software what the ones and zeros represent, or whether the data is…

“Should I use my new NVMe or old SATA SSD for booting Windows 10?”

The general rule is: Put the operating system, and your other most-frequently-accessed files, on the fastest drive. NVMe drives can be faster than classic SATA drives; but the fastest SATA SSDs are faster than some run-of-the-mill NVMe SSDs. Plus, some of the spec-sheet advantages of NVMe may not matter all that much under real-world conditions….
