Why are hard drives installed on TerraMaster DAS not recognised by computers with Windows XP operating system?

This is likely caused by the fact that the hard drive installed on TerraMaster DAS has a capacity exceeding 2TB, which is unrecognised by Windows XP OS. If this is the case, another OS should be used. A 64-bit system is recommended for hard disks with large capacity, as hard drives with a capacity exceeding 6TB are not recognised by some 32-bit systems.
