When I switching the drive from Fixed Disk to Removable Disk, there is a small unallocated partition. Where did this come from?

Question:When I switching the drive from Fixed Disk to Removable Disk, there is a small unallocated partition. Where did this come from?
Answer:We recommend repartitioning/formatting the drive when switching it from Fixed to Removable or visa versa. If you set up the drive as fixed and use a GPT partition style, this will create a small UEFI partition on the drive. If you switch the drive, from Fixed to Removable, the drive will then use an MBR partition style and the UEFI partition will appear as unallocated/formattable space. For this use case, we recommend re-setting the drive, or using Diskpart commands to clean the drive. Then create a new partition and format the drive. This will delete the “hidden” UEFI partition. Using MBR partitions for Fixed drive will not create the UEFI partition.
