Here are a few points to keep in mind:

1. FAT32 has limitations in terms of file size (maximum 4GB) and partition size (maximum 2TB). While it's compatible with both macOS and Windows, it might not be the best choice for large files or drives.

2. Sometimes, formatting a drive using macOS can introduce certain filesystem configurations that may not be fully compatible with Windows. This can lead to issues when trying to access the drive from Windows machines.

Solution 1: To ensure seamless file transfer between macOS and Windows, consider using exFAT as the filesystem format. It's compatible with both operating systems and supports large file sizes and partitions.

Solution 2: Checking Drive Health: Ensure that the WD My Passport drive is healthy and not causing the issue. You can use Disk Utility tools on macOS to check and repair the drive if needed.

Solution 3:  If the FAT32 drive continues to have issues, you might consider alternative methods for transferring files, such as using cloud storage services like Google Drive or Dropbox, or using a different external drive formatted with exFAT.

Overall, the key is to find a filesystem format that across both macOS and Windows to avoid compatibility issues during file transfers.
