If a drive runs at a lower UDMA mode (e.g., UDMA2 or UDMA4), check for a proper 80-conductor cable and ensure it's fully seated.
Inspect BIOS/UEFI settings to confirm the controller is in Auto/UDMA mode rather than PIO.
For Western Digital drives, check firmware and model-specific docs—vendor tools (e.g., WD Data Lifeguard) can report transfer mode and diagnostics.
If you see errors like CRC errors or device falling back to PIO, replace the PATA cable and test different controller ports.
When cloning or imaging drives, be aware actual sustained throughput may be lower than 133 MB/s due to drive mechanics and filesystem/OS overhead.

If you are looking for the official media library for the German broadcaster WDR:

Confusion on the Name: The broadcaster does not release software called "WDR UDMA v6." The official apps are WDR aktuell, ARD Mediathek, or apps for Smart TVs (LG/Samsung) and streaming sticks (Fire TV/Roku).
The "v6" mix-up: You might be seeing a version number for a specific firmware on a TV box or a specific build of a third-party app accessing WDR content.
Verdict: If you want to watch WDR (German TV), do not download a file named "WDR UDMA v6." Instead, download the official ARD Mediathek or WDR aktuell app from the official Google, Apple, or Amazon store. The official apps are high quality, free, and legal.
