If your disk won’t initialize, first verify that the SATA and power connections are secure and that the drive is detected in the BIOS.
Then, in Windows Disk Management, right‑click the “Not Initialized” drive and choose to initialize it.
If initialization fails, try using DiskPart from Command Prompt to clean and re-partition the disk.
Also, check for any available firmware or driver updates from WD.
Could you please specify which operating system and system you are using, as the procedures might vary depending on the setup?
