No drive — SSD, HDD, magnetic tape, wire spool, paper tape, whatever — no drive can make that guarantee! But the data on any kind of drive should survive the drive’s careful removal, proper storage, and re-installation. Mostly, it depends on how you handle the drive. SSDs should be handled the same as an HDD…

Quora.com makes my head hurt.
Quora.com — it’s a question/answer forum of unvetted, wildly-varying content quality — uses software to determine who sees which questions. The Quora software knows I’ve written about operating systems. And it knows I’ve written about Windows in particular. And it knows I’ve written about bugs in software. So, the Quora software sent me this question…
“Why do HDDs seem to follow a doubling rule (256GB, 512GB, 1TB, etc.), but SSDs don’t?”
(Answer requested by Nelson Vidinha) Because you can’t add half a platter to an HDD. HDD capacity is usually added in large-ish chunks, a platter at a time. An HDD might have one, two, or many platters. For each drive type and geometry, there’s a commercially-ideal capacity per platter. Hence: drive capacity commonly goes up…

Smartphone cameras have come a long way
I recently got a new Samsung Galaxy S10, and have been playing with its three rear cameras. If you follow smartphones, or cameras, you probably have seen comparison and demo pix taken by professional reviewers to show the capabilities of the new crop of smartphone cameras. You’ve also probably seen the studio-quality promotional shots taken…
“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…
A reader asks: “Can getting the password wrong too many times make your phone factory reset?”
Yup. It’s a security feature, so that a hacker or thief won’t have an infinite number of chances to break into your phone. For example, Android 9 (“Pie”) on a Samsung, will optionally perform a factory reset after 15 consecutive failed logons/unlocks. Not all phones do this; and the exact verbiage, number of allowed attempts,…
40 Years Ago Today: World’s 1st Cell Phone Call
Forty years ago, a test call was made using a prototype of the first fully-portable commercial cell phone: A Motorola DynaTAC 8000X . A full charge took roughly 10 hours and yielded 30 minutes of talk time (no data, of course). When it went on sale, it cost $3,995; equivalent to almost $10,000 today. (More…
Got a minute? Got HD or 4K?
The folks over at Arstechnica found a very short (just 61 sec!), never-before-seen-by-the-public, video of SpaceX’s most visually-spectacular moments from 2018. This is different from SpaceX’s live and streaming videos. They’re awfully good, but are usually shown at reduced resolution; and often show some artifacting. But this video is apparently direct from higher-resolution source files,…
