AMD's SSD Write Bug Is Fixed — But How Much Life Did Your Drive Lose?

The bug, in one paragraph: what Adrenalin was doing to your SSD

AMD has shipped the fix. Adrenalin 26.11.1, released today as an optional driver, addresses a bug where Radeon RX 7000-series and newer cards caused excessive writes to the system drive while the PC sat idle. In plain terms: your graphics card software was quietly hammering your SSD in the background, even when you weren't doing anything.

Why does that matter? Because SSDs have a finite number of write cycles — that's the TBW (terabytes written) rating you'll see on any drive's spec sheet. Every write chips away at that budget. A card that keeps writing while the machine is idle burns through the drive's lifespan with no visible symptom whatsoever. No slowdown you can point at, no error message — just wear accumulating in the dark.

And here's the part that matters most: the fix stops the damage. It does not undo it.

Update this week if you run a Radeon RX 7000 or newer

The driver is labelled "optional", but if you're on an affected card, treat it as anything but. Install it this week. Every day the old driver stays on your machine is another day of unnecessary writes to the drive holding your operating system, your documents and everything else.

Updating a GPU driver is a quick job if you're comfortable doing it. If you'd rather not touch drivers yourself — plenty of people don't, and we don't blame them — it's exactly the kind of thing we do alongside other work. Bring the machine in for a health check and we'll sort the driver at the same time.

Worth noting: it's driver-update week on both sides of the fence. NVIDIA also shipped GeForce 621.24 WHQL Game Ready drivers today, so whichever camp you're in, there's a fresh driver waiting.

And if this bug has you factoring driver reliability into an AMD-vs-NVIDIA decision for a new machine, fair enough — that's a legitimate data point. Our custom PC build service handles the whole thing, drivers included, if you'd rather start fresh than patch.

And if this bug has pushed you towards a whole new build rather than another patch, now's the moment — we've looked at the supply picture and November 2026 genuinely beats January 2027 for upgrading your PC.

The question nobody else is asking: how much life did your SSD lose?

Most coverage of this bug stops at "there's a fix now". We think that's the wrong stopping point.

Every SSD has a TBW rating — the amount of data the manufacturer says the NAND can take before it's outside warranty territory. At 1TB, common ratings sit somewhere between roughly 300 and 600 TBW, with premium drives rated higher — the exact figure is on your drive's spec sheet if you want to check your own model.

But this bug wasn't normal use. Excessive background writes, running every hour the PC sat idle — and if that went on for weeks or months on your machine, it adds up. Because the drive kept working normally the whole time, most owners had absolutely no idea it was happening.

The fix doesn't restore any of it. NAND wear is permanent: once a memory cell has been through its write cycles, they're gone. So the real question isn't "is there a fix?" — there is. It's "is my drive still healthy enough to trust?"

That's the question we'd be asking if we ran a Radeon card today.

How to read SSD wear: SMART indicators explained (not a walkthrough)

Every modern SSD reports its own health through SMART — Self-Monitoring, Analysis and Reporting Technology. Tools like CrystalDiskInfo read those numbers and present them, usually as a health percentage. Here's what the key figures actually mean:

• Health Status / wear percentage — derived from the drive's wear levelling count and spare-block reserves. This is the headline number: how much of the drive's rated life has been consumed.
• Total Host Writes / Total Bytes Written — how much data has actually hit the drive since new. On an affected Radeon machine, this figure is the smoking gun: if it's far higher than your usage could explain, the bug's been busy.
• Percentage Used — the NVMe-standard figure for consumed rated life. It's the one to watch.
• Remaining spare capacity — the drive's reserve of fresh memory blocks. When this runs low, the drive is on borrowed time.

A rough guide: 0–10% of rated life used is healthy. 10–50% is worth watching. Above ~80%, plan a replacement.

We're deliberately not giving you a full click-by-click self-diagnosis routine, and here's why: a proper health check doesn't stop at the wear percentage. It also looks at reallocated sectors, pending sectors and the drive's error logs — and a borderline reading (say, 55% used with a handful of reallocated sectors) is exactly where interpretation matters. That's the difference between "fine for another two years" and "back this up today". We run that full inspection as standard on any machine that comes through the workshop.

Why this mimics the "slow laptop" complaints we see every winter

We've written before that slow-machine complaints spike every November as usage hours and update cadence increase — it's a pattern we see across the counter every year. A worn SSD behaves exactly like the generic "my laptop's got slow" complaint we hear all season: long boot times, apps stalling, files taking an age to open.

It gets worse. A drive near its wear limit can throw intermittent read errors that look for all the world like malware or a Windows problem — files that won't open one day and work fine the next. We've seen plenty of machines come in suspected of infection when the drive was the actual culprit.

So if you run a Radeon card and your machine has felt sluggish lately, the SSD deserves suspicion before anything else.

One caveat from our workshop experience: the most common cause of a slow laptop is still a mechanical hard drive, followed by 8GB of RAM that's full under normal use. A worn NVMe is the rarer variant — but it's nastier, because a mechanical drive tends to degrade gradually and audibly, while a worn NVMe can fail suddenly and completely.

What a worn NVMe replacement costs

If the health check does show significant wear, here's where you stand.

In our workshop experience, most laptops from the last five or six years take an NVMe SSD; older machines take a 2.5-inch SATA drive instead — that's the split we see daily across the counter. For a modern machine:

• A 1TB NVMe replacement, including the drive, fitting and transferring Windows and your files across, typically lands in the low-to-mid £100s as of November 2026. Exact quotes depend on the drive grade and capacity you choose, and we quote current pricing on every job — drive prices move weekly.
• If the old drive is still readable, we clone it, so nothing is lost and you get the machine back looking exactly as you left it.
• If it's already failing, it becomes a data recovery job first — more on that below.

Students and NHS staff get our discount, and we collect and deliver across Portsmouth for £10 each way — or you can drop the machine off at the workshop on Durham Street.

If you're already planning other work — a RAM upgrade or a driver tidy-up — doing the SSD at the same time keeps the whole thing to one visit.

If the drive is already misbehaving: recovery comes first

Some of you won't be planning a replacement — you'll be reading this because the drive is already playing up. The signs a drive is past saving:

• Files disappearing or refusing to open
• The drive dropping out of Windows entirely, then reappearing
• Long freezes whenever you access files
• SMART warnings at boot

If that's you: stop using the machine now. Every extra write to a worn drive reduces what's recoverable. Don't run backups, don't "just check" things — power it down.

Our data recovery service handles drives in exactly this state, and if the data comes back clean we can fit the replacement drive in the same job — one collection, one visit.

What to do this week — the short version

1. Radeon RX 7000 or newer? Update to Adrenalin 26.11.1 this week. The "optional" label is marketing, not advice.
2. Then get the drive's health checked. The fix stops future wear but says nothing about wear already done — and that's the number that decides whether your drive is trustworthy for another three years or another three months.
3. If it needs replacing, a 1TB NVMe with fitting and Windows transfer runs low-to-mid £100s, with student and NHS discounts available.

We can do all three in one visit: update the driver, run a proper SMART health check with error logs, and fit a replacement drive if it comes to that. Collection and delivery across Portsmouth is £10 each way, or drop the machine in — ring us on 02392 733174.
