A:Answer Windows XP only reads drives using a Master Boot Record (MBR) partition type, while any drive over 2TB generally comes preformatted with GUID Partition Table (GPT), as the MBR partition reaches a maximum table size of 2TB and can't be expanded without making an additional partition. This drive, being an 8TB drive, would need to be reformatted with an MBR partition table, then partitioned in to 4 2TB partitions, making this drive appear to be 4 drives in one. The oldest version of Windows that can use GPT is Windows 7, which is 8 years old at this point, and Windows XP is nearly 16 years old. If you plan to use the latest hardware, please consider using a more modern operating system to prevent issues with compatibility.
