ClonerAlliance UHD Pro works with all formats of USB flash drives and external hard drives.

ClonerAlliance UHD Pro works with all formats of USB flash drives (NTFS, FAT32, exFat) and external hard drives (MBR, GPT).

Besides, ClonerAlliance UHD Pro works with an over-2TB external hard drive. But due to the maximum capacity limitation of FAT32 and NTFS format, if you use an over-2TB external hard drive and don’t want to partition it, please format it to exFAT, which will work normally. If you want to use NTFS/FAT32, please partition it first, otherwise it will not work.

File system limitations:

FAT: The single file can be 2GB at most. The maximum capacity of the partition is 2GB.

FAT32: The single file can be 4GB at most. The maximum capacity of the partition is 128GB.

NTFS: The single file can be 2TB at most. The maximum capacity of the partition is 2TB.

exFAT: Theoretically, there’s no limitation on the single file size and maximum capacity of the partition.
