Solved Drive partitions query?

Alexey2912 · Oct 7, 2022

Hi,

Posting screen captures from MR and Disk management, I see 5 partitions on MR and 4 in DM. Is that normal?

Thanks.

Could be correct, especially when Upgrading from an earlier version of Windows or if drive came from a different computer, usually will have some very small sizes. They usually cause no issues until one gets deleted, could prevent starting Windows. And they have no drive letters assigned on purpose, not intended for normal access from File Explorer or older Windows Explorer.

#2 16 MB partition seen in Reflect is not visible in disk management. Is it normal, or got deleted and I require to restore the full backup?

The laptop running W11 Home is stable, none issues starting, rebooting.

Thanks for the reply.

If no drive letter assigned File Explorer doesn't know about it but third-party programs can, I wouldn't worry about it except if those unlettered partitions are deleted it will affect Windows startup. As for a backup program restoring any deleted partitions it may be necessary or if can't be done can lead to resetting/recovering/reinstalling of Windows. Just as with changes to the Registry, any partitioning work carries dangers.

It’s the MSR partition and does not contain a partition ID so it won’t show up in diskmgmt. Normal

Simply I should be concerned, or would you recommend using a 3rd party app like MiniTool to recheck?

Thanks.

Macrium Reflect reports disk with 16MB partition. What is that ?
