- Test on Another Device: If possible, connect the drive to another compatible device to determine if the issue is with the drive or the original device.
- Check Disk Utility/Management: On macOS, open Disk Utility. On Windows, open Disk Management. See if the drive is listed, even if it's not mounted. You may need to initialize or format it if it's a new drive or has become corrupted.
5.2 Slow Transfer Speeds
