AMD Radeon SSD Write Bug Gets A Fix From ‘necanditool’, Whose Open-Source Tool Stops atieclxx.exe Copying Itself Every Second
An AMD Radeon GPU driver bug causes the atieclxx.exe process to copy itself every second, generating continuous write traffic that degrades SSD health. AMD has acknowledged the issue and promised a fix. In the meantime, an open-source utility named necanditool stops the runaway process, serving as a stopgap for affected users. One Radeon owner reported the External Events Utility consumed roughly 1% of SSD health per month for over a year. The bug mirrors an older AMD chipset driver issue that similarly wore down SSDs.

AMD Radeon GPU driver bug continuously writes to SSDs; open-source tool 'necanditool' stops atieclxx.exe loop
An AMD Radeon GPU driver bug causes the atieclxx.exe process to copy itself every second, generating continuous write traffic that degrades SSD health. AMD has acknowledged the issue and promised a fix. In the meantime, an open-source utility named necanditool stops the runaway process, serving as a stopgap for affected users. One Radeon owner reported the External Events Utility consumed roughly 1% of SSD health per month for over a year. The bug mirrors an older AMD chipset driver issue that similarly wore down SSDs.
Why it matters
The defect resurrects a known AMD Windows chipset driver problem that quietly shortened SSD lifespan, now reappearing in GPU drivers. Continuous background writes accelerate wear on flash memory, potentially leading to premature drive failure and data loss. AMD's admission and commitment to a patch indicate the issue is confirmed and not isolated. Users running Radeon GPUs on Windows should monitor SSD health metrics and consider the open-source mitigation until an official driver update arrives.
What is confirmed
- AMD Radeon GPU driver bug causes atieclxx.exe to copy itself every second, writing continuously to SSDs.
- AMD has admitted the bug exists and promised a fix in a future driver update.
- An open-source tool called necanditool stops the atieclxx.exe loop as a stopgap measure.
- A Radeon owner reported the External Events Utility used about 1% of SSD health per month for over a year.
- The bug resembles an older AMD chipset driver issue that also degraded SSDs.
What to watch next
- Release of official AMD GPU driver containing the fix
- Independent verification of necanditool effectiveness across GPU models and Windows versions
- Long-term SSD health data from users applying the stopgap or updated driver
