Why we replace the drive even when it boots fine
Tested and boots fine is not the same as will not fail in six months. A real failure mode buyers rarely hear about.
A computer that boots, logs in, and runs clean can still be carrying a drive that is about to fail. Six units came through our OptiPlex refurb pipeline recently, and every one of them tested at 94 to 98 percent reported wear on its original drive, well inside the range where failure is a matter of when, not if. All six got a fresh drive before they ever reached a listing.
What drive-wear telemetry actually measures
Every SSD tracks its own wear as part of its SMART data: a running estimate, reported by the drive itself, of how much of its usable write life has been consumed. Zero percent is a fresh drive. Numbers approaching 100 mean the drive’s own controller expects to be near the end of what it was built to handle reliably, regardless of whether it currently boots and reads files without complaint.
A drive at 94 to 98 percent wear can still pass every test you would normally run on it. It boots. Files read and write. Nothing looks wrong at a glance. The number that tells you something is wrong is not visible unless you actually pull the SMART data and look at it.
One of the six carried close to 60,000 power-on hours alongside its 94 percent wear figure, and the repair ticket for that unit flagged it plainly as near end of life. The drive still reported itself as healthy in the basic sense, no read errors, nothing thrown yet. Healthy and near end of life are not opposites here. A drive can be functioning correctly today and still be the wrong drive to ship in a machine you are selling.
Six units, same story
Across a recent batch of OptiPlex desktops through our bench, six drives came back reporting wear in that 94 to 98 percent band, some flagged outright as near end of life. Every one of them got swapped for a fresh drive, re-imaged, and tested clean before the unit was listed. None of those six shipped on the drive it arrived with.
Boots is not the same standard as will not fail
A quick test tells you a machine works right now. It does not tell you anything about the six months after you own it, and a drive at 95 percent wear is exactly the kind of problem a quick test cannot catch, because a worn-out drive works fine right up until the moment it does not.
That gap, between passes a five-minute check and will hold up, is where most of the real risk in a refurbished computer actually lives.
What this means when you buy from us
A drive check is part of the standard test, not an extra step we skip when a machine happens to boot cleanly. If a drive comes back worn, it gets replaced before the machine is listed, every time, which is why none of those six units shipped on the drive it arrived with.
The takeaway for any refurbished PC
Boots and passes a quick test is a low bar. Ask what was actually checked, specifically whether the drive’s own wear data was pulled and looked at, not just whether the machine turned on. That one question tells you more about whether a refurbished computer will still be working in a year than anything you can see in a listing photo.
