What does IDE (PIO mode 0) represent?

IDE (PIO mode 0) is the slowest CPU-driven ATA timing mode used for very old IDE drives, involving software-driven data transfers without DMA.

Why convert IDE (PIO mode 0) to IDE (UDMA mode 1)?

Converting helps translate slow PIO transfer timings into the faster DMA-driven UDMA mode, aiding in diagnostics, benchmarking, and hardware configuration on vintage PCs.

Does this conversion reflect data size?

No, it reflects relative data transfer speeds between timing modes, not direct amounts of transferred data.
