READ A MAC DRIVE ON WINDOWS 10 ETHERNET DRIVER
When the drive isn't available on your computer, it could also be a driver issue. In the case that you already tried the recommendations to address connection, initialization, and formatting issues, it could mean hardware failure, in which case you should consider getting a new drive. If Windows 10 doesn't detect the drive correctly, and it appears in Disk Management with the Unreadable status, you're experiencing read and write errors, corruption, or hardware failure.
If you can't get the storage online, and it was recently available, that could mean the drive is corrupted, disconnected, or it's not getting power.
