Solved RwDrv.sys Caused DRIVER_IRQL_NOT_LESS_OR_EQUAL When Unplugging External Drives

magnifia_magnus · Feb 28, 2024

Hi everyone, please help me identify the root cause and how to troubleshoot. Below I provide the info related with the case.

Frequency of incident: Random

Steps to reproduce:

Plug any external drives (Seagate, WD Elements, WD My Passport)
Unplug with or without safely removing first. Both didn't matter.
Gets BSOD

This is so frustrating as the BSOD often wiped my ongoing work which involves frequent back and forth of connecting external drives. Please help me and thank you!

Got it.

I attached the Tuneup.log. Link

Thanks!

zbook · Feb 29, 2024

Tune up results were good.

Once there is more free space Windows can create and maintain memory dumps should there be any new BSOD.

magnifia_magnus · Mar 2, 2024

I uninstalled then reinstalled Legion Fan Control, which so far has fixed the issue after multiple attempts of connecting and disconnecting HDD. It was enlightening to know the source of the malfunctioning service.

I haven't tried updating BIOS or DDUing Nvidia Driver, since I'm pretty comfortable with the current version and don't want risk unknown bugs.

Many thanks Zbook!

The computer logs indicated: BSOD and hangs and / or freezes

The misbehaving Legion Fan Control driver had caused the BSODs.

The misbehaving Nvidia GPU driver had caused the hangs / freezing.

If there are any recurrent hangs and / or freezes then replace the Nvidia GPU driver.

You're welcome.
