Confusion about partition during use of BU Imager - Unknown Partition
Confusion about partition during use of BU Imager - Unknown Partition
I've experimented with various new Imagers for Windows 11. Previously, I relied on Acronis True Image (released in 2016). With Acronis, it would automatically identify and safeguard the Recovery Partition and the EFI Systems partition whenever I chose to back up my main drive, which contains the operating system.
With other Imagers I've recently tried, besides the OS, Recovery, and EFI partitions, I'm encountering an unidentified third partition that Disk Management in Windows doesn't recognize. When using Hasleo or EaseUS imager, the following details appear:
Other... 0 free of 128mb
NTFS... 51.71 mb available from 485 mb
FAT32... 73.39 free of 100mb
The names shown correspond to those listed by Hasleo or other software. In Disk Management, the "FAT32" is marked as the "Healthy" EFI partition. It remains unmarked for NTFS-485mb, which I suspect is the Recovery partition. The "Other" partition isn't visible in Disk Management at all.
Acronis handled this automatically, backing up both the EFI and Recovery partitions along with my OS drive. However, it never detected the "other" partition. I'm curious whether this "Other" partition exists, if it was created during installation, or if it's just an error from my past partitioning attempts.
I'm planning a fresh Windows 11 installation soon. I'll check if it generates an additional drive. If not and you don't see it either, I assume it might be an oversight I made during setup. It's odd that Disk Management doesn't recognize it, even though it's completely full. Please let me know if you can shed any light on this matter.

I saw some mention of a third data partition being acceptable, though I'm not familiar with it. Someone else has likely heard of it too. The reason it appears fully filled and shows up in Disk Management is probably because of recent changes or updates.
Doesn't seem like Tom provided an option for image uploads, so...

You've been in the US for a while. Have you ever come across a "data" partition that's completely full and hidden from Disk Management?
The other image resembles a similar scene from Hasleo, but it appears consistently when using EaseUS todo.
The only possibility I recall is from a time when a hard drive failed and was replaced. It now shows as Disk 1, but the replacement drive was assigned to Disk 1 instead. I don't remember the exact details, but I thought about mentioning it just in case it's relevant.
Also, that site is really useful. It lets you upload images quickly and easily without needing to log in. Files are deleted automatically after six months.

Not sure if this helps, but I just ran diskpart...
Disk 0 is now the chosen disk.
Listing partitions shows various details about their sizes and offsets.
Switching to disk 1 also displays the current selection.
Listing partitions reveals specific information about each partition type and size.
The 128 MB drive appears in the results, indicating it’s present on Diskpart.
It seems to be a Windows-specific feature. I can provide more details about it. The reason for its creation is unclear, but it serves a particular purpose. It's designed to function differently from other partitions like EFI and Recovery. Including it in backup processes might not be standard, which could explain why it isn't reported in Disk Management. Most users likely don't encounter it unless they're backing up the OS partition specifically.
