Area of Cosmos - What area of Cosmos are we dealing with?

Getting a list of disks.

Expected Behaviour - What do you think that should happen?

Two discs, two partitions. One partition on one disk.

Actual Behaviour - What unexpectedly happens?

Virtual machine screenshot:

Reproduction - How did you get this error to appear?

I used the following loop:

...
List<Disk> disks = vfs.GetDisks();

for (int i = 0; i < disks.Count; i++)
{
    Console.WriteLine("==========");
    disks[i].Mount();
    disks[i].DisplayInformation();
    Console.WriteLine("==========");
}
...

Version - Were you using the User Kit or Dev Kit? And what User Kit version or Dev Kit commit (Cosmos, IL2CPU, X#)?

Dev Kit (Cosmos commit)

Note: A CD and one hard disk are connected to my virtual machine.

Hello, could you send me a screenshot of you virtual machine devices and if you can even the list of partitions you're using from your computer?

Hello. Here is a screenshot of my virtual machine devices.

You can also see in the picture that the disks have the same size.

The amount of partitions seem fine, since the ISO has 3 partitions since the change to UEFI iirc, and not sure who called it "Block Partitions" but that isnt the amount of partitions, very confusing naming I agree but this seems, apart from the naming, fine.

[GoldenretriverYT]

yup the ISO has 3 partitions

I have two partitions with the same directories (boot and EFI).
