It can happen with a disc from any manufacturer. MediaKit reports not enough space on device for requested operation.Īfter several attempts, I tried formatting to HFS+, and get the same error. I started up the Disk Utility and tried to Erase it and make it APFS, but every time I try, I get the following error: The easiest way to format the drive is by using macOS built-in Disk Utility app. So the only workaround is to format the drive to HFS+ or APFS. MacOS can read but not write to NTFS formatted drives. But most WD drives come formatted in the NTFS file system format for OS Windows, while for macOS we needed the HFS+ format or the Apple’s brand new APFS (Apple File System) format. A Western Digital company says that it can be used on both Windows and macOS. Today I bought a brand new external hard drive WD Elements Portable 1Tb.
