- If you have multiple drives on this system, you can specify a different location for the database files after installation of SQL Server is complete. Make sure that drive reflects a supported sector size when querying the `fsutil` commands. SQL Server currently supports sector storage sizes of 512 bytes and 4096 bytes.

- You can add a registry key, which will cause the behavior of Windows 11 and later to be similar to Windows 10. This will force the sector size to be emulated as 4 KB. To add the `ForcedPhysicalSectorSizeInBytes` registry key, use the [Registry Editor](#registryeditor) or run commands as described in the [PowerShell as Administrator](#powershellasadmin) section.

> [!IMPORTANT]
> This section contains steps that tell you how to modify the Windows registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, see the [How to back up and restore the registry in Windows](/troubleshoot/windows-server/performance/windows-registry-advanced-users#back-up-the-registry) article.
