AMD is investigating a Radeon driver problem that users say keeps writing to their SSDs even when their PCs are idle. Tom’s Hardware reports that the company has acknowledged the issue, with one owner claiming their drive’s reported health fell by 1% each month for 16 months. The reports point to AMD’s External Events Utility, although the effect on SSD lifespan has not been independently established.
VideoCardz reports that AMD is targeting Adrenalin 26.11.1 for a correction later in November. It attributes that expectation to AMD representative AMD_Vik, who also described an apparent interaction between the utility and Microsoft’s PCIe filter driver. There’s no exact release date, so affected owners should check for the fix in the release notes when the update arrives.
Why a small write rate adds up
The process under scrutiny is atieclxx.exe, the AMD External Events Client Module associated with the External Events Utility. The service handles display-related tasks such as monitor detection and Radeon software hotkeys. Users have reported continuous writes of around 0.3-1.5MB/s, with one report reaching approximately 5MB/s while the machine was idle.
At a sustained 5MB/s, the arithmetic works out to about 18GB an hour, 432GB a day, or almost 13TB over 30 days. Those totals assume uninterrupted activity at that rate; they aren’t measurements from a month-long test. Tom’s Hardware also cautions that reported host writes don’t directly establish how much data reaches the NAND flash, because SSD controllers manage incoming data through caching, wear-levelling, and other techniques.
That leaves the monthly health-loss claim as an individual owner’s account rather than a measured outcome for Radeon systems generally. VideoCardz reports that some owners see no unusual activity even with Adrenalin 26.10.2 installed. Checking the process on your PC is therefore more useful than assuming that installing Radeon software has damaged your drive.
Check the activity before changing settings
VideoCardz describes a straightforward check in Windows Resource Monitor: press Win + R, enter `resmon`, open the Disk tab, and sort by write activity. Look for sustained writes associated with atieclxx.exe while the PC is otherwise idle. Unlike a foreground benchmark, this checks what a background driver component is doing, a separate concern from Microsoft’s recent Windows 11 responsiveness claims.
Users have reported that stopping AMD External Events Utility or disabling Resizable BAR can reduce the unwanted activity, but VideoCardz says neither workaround succeeds in every case. Stopping the service can interfere with hotkeys and display functions, while disabling Resizable BAR may reduce gaming performance. We recommend checking for the symptom first rather than changing BIOS settings solely because you’ve seen the warning.
The issue arrives as AMD faces broader questions about its gaming business following Lisa Su’s description of the company as “data center first”. For Radeon owners dealing with this particular bug, the immediate priority is a driver correction. Until it arrives, keep a record of persistent idle writes so you can compare the same behaviour after updating.
Does this bug affect every Radeon PC?
No. The reports cover multiple driver releases, but VideoCardz also describes users who see no unusual write activity. Resource Monitor can help you check whether atieclxx.exe is continuously writing on your system.
Should I disable AMD External Events Utility?
Check for persistent writes first. Users have reported success with disabling the service, but it can affect display functions and Radeon hotkeys, so it’s a workaround with trade-offs.
Which driver is expected to fix the problem?
VideoCardz identifies Adrenalin 26.11.1 as the expected fix. Check its release notes for confirmation before relying on it to resolve the issue.
