Reports say AMD has acknowledged a Radeon software issue that can cause persistent background writes to the system drive on some otherwise idle Windows 10 and Windows 11 PCs. The activity has been linked to atieclxx.exe, part of AMD External Events Utility. AMD’s reported fix has no confirmed release date, and the available evidence does not establish exactly when it will ship.1

What’s known—and what isn’t
Users have reported sustained disk activity associated with atieclxx.exe across Radeon hardware and multiple Adrenalin driver versions. Reported rates vary: one account describes roughly 0.3–1.5 MB/s, while another reports about 5 MB/s. These are reported observations, not a confirmed rate on every affected system.5
6
AMD External Events Utility is associated with display-related functions such as detecting monitor connections, handling display hotkeys, and supporting FreeSync-related behavior.4 One report suggests a possible interaction with Microsoft’s PCIe filter driver, but the supplied evidence does not independently establish that as the cause.
26
AMD’s reported position is that the behavior appears to be a real bug and that a fix is planned for a future driver, with no date announced.1
2 Another report says a correction has entered testing, but the available material does not confirm final validation, completion of testing, or a release version.
26
Adrenalin 26.10.2 is dated October 30, 2026, but the supplied records do not verify whether it contains a fix. Nor do they establish that the issue will miss a particular upcoming release or that AMD has promised a specific release-note confirmation.8

What 432 GB per day means
At a sustained 5 MB/s, multiplying by the seconds in a day gives about 432 GB of reported write activity per day, or 12.96 TB over 30 days using decimal units. That is a rate-based estimate, not a measurement of how much data the SSD’s flash memory physically programs.3
6
A process-level Windows write reading does not, by itself, establish the drive’s actual host writes or physical flash writes. So the estimate alone cannot show how much SSD endurance is being used or prove that the bug has shortened a drive’s life. The available sources do not provide drive-specific endurance data or measurements of resulting SSD wear. Owners of lower-endurance drives may reasonably want to monitor activity, but the reports do not quantify damage to those drives.
How to check for persistent writes
- Open Windows Resource Monitor by searching for
resmon. - Select Disk and sort by Write (B/sec) while the PC is otherwise idle.
- Check whether
atieclxx.exerepeatedly appears with sustained write activity. A brief or isolated spike is not the same as continuous activity.
A guide to checking the process and service on Windows 10 and 11 also recommends checking the activity on your own system rather than assuming every Radeon PC is affected.2 If you want to assess longer-term storage activity, compare the SSD’s reported write counters over a measured interval; a single process reading does not establish physical flash writes.
Workarounds: proceed cautiously
Stopping AMD External Events Utility temporarily through services.msc can serve as a diagnostic test: compare disk activity before and after stopping it. Because the utility is associated with display events and hotkeys, disabling it may affect those or other dependent Adrenalin features.4 Treat this as a reversible test, not a confirmed permanent fix.
A user report says that copying older PCI bus driver files from version 26.3.1 stopped the activity on one system. That is anecdotal evidence, not an AMD-approved or broadly tested solution; the report itself notes a lack of long-term testing.14 Avoid mixing driver files unless you understand the risks of mismatched versions and are prepared to restore the original files.
The supplied sources do not establish disabling Resizable BAR as a reliable workaround. The most cautious approach is to verify that the activity is persistent on your PC, avoid unsupported driver-file changes, and wait for AMD to document an official correction.
