Hello,
Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.
There is a 24H2 compatibility hold for some Western Digital (WD) SSDs. This means those SSDs may not be able to update to Windows 11 version 24H2 yet.
Please check your PC manufacturer’s website or the WD website to see if there is a firmware update for your SSD.
Important: Before updating the firmware, make sure to back up all important files.
You can use the Western Digital Dashboard to check for firmware updates:
