Unable to access device in Partition Manager, nor modify its contents

I’m rather surprised that this state of affairs is so poorly explained to the user.

Tangentially, another situation is similar:

Why can't I modify the partition table on an HDD (identified as a RAID device)?

I’ve extracted some SATA HDDs from a defunct NAS. When I view them in mmc diskmgmt.msc under Windows 11 Pro 24H2, I am able to format partitions. However, when viewed via kde-partitionmanager-25.04.3-1.fc42.x86_64, I am unable to see information about the HDD: …much less modify it: [Screenshot] Additionally, I’ve not configured RAID, so even if it used to operate in a RAID array, it doesn’t now. Though, on that note, both drives appeared to contain quite different data, so I’ll be surprised…
