Unable to format WD my passport ultra

I have a WD my passport ultra, and I haven’t used it for a while until now, but it is corrupt. There is an NTFS volume, and an HFS volume. The NTFS volume mounts, but the HFS won’t mount, and I can’t reformat either volume, or initialize the disk to begin with. I get various errors about posix including permissions, and I get the error unable to open device. I have a utility that allows me to write to the NTFS partition, but it is slow. I used a disk speed test, and it starts at 100 mbps, then drops to 42 then 8, and eventually 1. Is there anything I can do or is the drive dead. I have tried multiple computers, windows, linux, and MacOS. Unfortunately this is a “legacy product,” and WD doesn’t provide support. The weird thing is I can still store files pretty reliably. I don’t care about data, just want the drive.


Have you tried using MiniTool Partition Wizard? It has helped me with issues I’ve had.
