My local MongoDB server is installed to my S: drive where the configs and logs live.

storage:
  dbPath: S:\MongoDB\data
{{}}

systemLog:
  destination: file
  logAppend: true
  path: S:\MongoDB\log\mongod.log

IE: it has no reason to access any other drive however it I found something periodically accessing my P: drive which is an external USB disk. I noticed this because the external drive normally likes to sleep since it's mostly idle but the unwanted access would occasionally force the it to wake up noisily.

Using Process Monitor I traced this to my mongod.exe process which appears to be querying disk space every 5 minutes:

3:01:03.0012146 PM mongod.exe 21348 QuerySizeInformationVolume P:\ SUCCESS TotalAllocationUnits: 1,465,097,471, AvailableAllocationUnits: 233,436,301, SectorsPerAllocationUnit: 8, BytesPerSector: 512

2:56:01.0028637 PM mongod.exe 21348 QuerySizeInformationVolume P:\ SUCCESS TotalAllocationUnits: 1,465,097,471, AvailableAllocationUnits: 233,436,301, SectorsPerAllocationUnit: 8, BytesPerSector: 512

3:06:05.0016549 PM mongod.exe 21348 QuerySizeInformationVolume P:\ SUCCESS TotalAllocationUnits: 1,465,097,471, AvailableAllocationUnits: 233,436,301, SectorsPerAllocationUnit: 8, BytesPerSector: 512

My first though was to disable the free cloud monitoring but this did not help. I scoured the manual page for the config and couldn't see anything either. I took a quick look through the git repository to try to see if I could trace back to where this was coming from but the trail went cold.

I would be great if whatever this diagnostic was could be turned off so my system can save power and reduce wear by letting the drive spin down.
