Mbamservice.exe causing external USB HDDs to wake


Recommended Posts

I have an external JBOD with archive drives in which are set to spin down when not in use.  'Something' kept causing them to spin up randomly and for no reason (ie. no access was requested of the drive).


I ran ProcMon and filtered the drives to see what process was causing them to wake - it turns out to be Mbamservice.exe.  I've set each drive to be excluded from all detections, but Mbamservice.exe continues to wake the drives from sleep (Explorer.exe then has to do some volume queries once the drives are awake but it's Mbamservice that triggers it).

Why is MWB ignoring the exclusion command and how can I ensure it leaves these external drives alone...?

Cheers.

Maybe its time to think about SSD.

I'm just asking, checking. I'm not sure that behavior can be stopped or not.

You're the first person I've seen with such a request

I'm pretty sure disabling the scheduler will stop the service trying to access those drives but it'd mean I'd have to regularly run scans myself (might as well revert to the free edition in that case..).

I'm not quite ready to pony up for that sort of capacity of SSD just for long-term archiving...

Again, I'm asking to check, verify if that works or not for you so that I can pass that along to our Dev Team.

With zero input or help on the issue then obviously nothing will change. I cannot promise it will change but I can submit the issue for review.

 

To begin, please do the following so that we may take a closer look at your installation for troubleshooting:

NOTE: The tools and the information obtained are safe and not harmful to your privacy or your computer, please allow the programs to run if blocked by your system.

  • Download the Malwarebytes Support Tool
  • In your Downloads folder, open the mb-support-x.x.x.xxx.exe file
  • In the User Account Control pop-up window, click Yes to continue the installation
  • Run the MBST Support Tool
  • In the left navigation pane of the Malwarebytes Support Tool, click Advanced
  • In the Advanced Options, click Gather Logs. A status diagram displays the tool is Getting logs from your machine
  • A zip file named mbst-grab-results.zip will be saved to your desktop, please upload that file on your next reply

Thank you

Hi AdvancedSetup,

Update: I think we can rule out scheduled scan being the issue - it's not due to run until 2am, however MBAMService.exe has just woken all the sleeping drives again exactly 2 hours since the last time (to the minute!).

I'll run the support tools tomorrow if I have time but tbh I suspect this is just MWB 'doing its thing' and regularly checking - the issue is I don't need (or want) it to check sleeping drives.  I'll do some more playing with settings and see what happens.  If it keeps doing it I'll just bin it off.

MBAMService.exe still popping up regularly on ProcMon.

AFAICS, surely excluding drives x/y/z from all detections should mean that MWB should simply treat them as if they don't exist; if it's not been asked to monitor them, surely it doesn't need to query/address the sleeping disk(s) every few hours...
