Windows is not trying to defrag the drive frequently? There is a bug that was fixed in the May 2020 update.
So I just checked and defrag settings for the drive, turned off Optimise Drives setting for the shared D drive.
Even through I've turned off chkdsk for D drive, when I powered on the laptop recently, it scanned D drive before booting into windows.
So I start looking at Event Viewer to see if I can find anything and scan seems to be sourced from Wininit (event ID 1001) which then seems to trigger Chkdsk to run even though I disabled Chkdsk by going into regedit, path:
Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager
BootExecute > Value data set to:
autocheck autochk /k *
(the /k
tells it to exclude D drive)
EDIT: The green smiley face is supposed to be characters colon and uppercase D (it keeps autochanging to the green smiley, not sure how to disable it)
