Setting DisableDeleteNotify of NTFS to 1 decrease the duration of format of both NTFS & ReFS in Windows Server 2016 & 2019

Question

I found that setting DisableDeleteNotify of NTFS to 1 decrease the duration of format of both NTFS & ReFS , I think it must decrease NTFS format duration only (Windows Server 2016 & 2019)

Answer 1

This is the command I used :

fsutil behavior set disabledeletenotify NTFS 1

& after that I used the command :

fsutil behavior query disabledeletenotify

to check that values are set correctly

Thank you

Answer 2

Hi,
Please tell me what command you used to set DisableDeleteNotify of NTFS to 1.
And you can use the following command to verify the current setting of NTFS and ReFS:
fsutil behavior query disabledeletenotify

Thanks for your time!

Hi bumping an old thread but if you are finding performance increases after using the disable delete notify option in fsutil and its on an ESXi Virtual Machine this could be the reason and it affects a lot more than just the format. It affects the whole of the VM's disk IO performance
