AMD Confirms Radeon Driver Bug That Writes to SSDs Nonstop - tech|
| (hx) 11:07 PM CET - Nov,09 2026 | AMD has confirmed a bug in its Radeon Adrenalin drivers that can cause continuous writes to the system SSD even when the PC is idle. The process responsible is atieclxx.exe, part of the AMD External Events Utility that handles display tasks such as monitor detection and hotkeys.
Users report write rates mostly between 0.3 and 1.5 MB/s, with one case reaching about 5 MB/s. At the higher rate, that can add up to hundreds of gigabytes per day. AMD staff acknowledged the issue on forums and Reddit, noting it appears linked to an interaction with a Microsoft PCIe filter driver. A fix has been submitted and is expected in Adrenalin 26.11.1, due later in November, though no exact release date is available yet.
Not every Radeon system is affected. Until the update arrives, owners can check Resource Monitor for sustained disk activity from atieclxx.exe. Temporary workarounds include disabling the External Events Utility service or Resizable BAR, but both can affect features or performance. |
