There are several disks with exFAT and NTFS partitions. NTFS partition disks are visible in the guest OS. Disks with an exFAT partition are visible as disks with a RAW partition. Can you tell me where my mistake is?

Guest OS with Linux Server 20.04 work with such disks correctly

It looks very likely that the problem appeared due to formatting of disks by means that do not fully comply with exFAT standards.
