976 In a Mac Pro, the SSDs are seen as external drives, how do I prevent accidental ejects?Feb-14-23
There is no provision in macOS to make SSDs on a PCIe card to appear as internal and non-ejectable. If you want to prevent accidental ejection, open a file on the volume with Text Edit, which will prevent macOS from ejecting the volume, because a file will be in use by Text Edit.

1077 Programming SSDs to 4k Block Size for Compatibility With macOS 10.13.6Feb-08-23
macOS 10.14.6 supports both 512 and 4k block size SSDs, but macOS 10.13.6 supports only 4k block size SSDs. Today, most SSDs are shipped from the factory programmed with a 4k block size. If your SSDs are programmed with 512 block size, however, and you need to be compatible with macOS 10.13.6, you must reprogram your SSDs to a 4k block size. Sonnet has written a script to do this, but it needs to be run on a Linux computer. You can download the instructions here. For a copy of the script, contact support@sonnettech.com.
