LSI MegaRAID SAS 9260 4i Driver

The LSI MegaRAID SAS 9260 4i is a storage RAID controller from LSI Logic, and its driver enables Windows to communicate with the controller and access the virtual disks it presents. When choosing a download for Windows 11, 10, 8, or 7, check the package’s compatibility details carefully—support can vary by driver release and system architecture.

Key Features

• RAID storage recognition: Allows Windows to detect and use virtual disks configured on the controller, rather than treating each connected drive as a separate volume.
• SAS and SATA storage access: Provides the operating-system interface for storage attached through the controller’s supported SAS and SATA connections.
• Storage I/O handling: Carries read and write requests between Windows and the controller, supporting access to files, applications, and system volumes.
• Controller status reporting: Helps Windows receive storage-device status and error information, which can assist with troubleshooting alongside compatible RAID management tools.

How to Install

1. Confirm the hardware and Windows version. Open Device Manager and identify the LSI MegaRAID SAS 9260 4i under Storage controllers or Other devices. Check whether your Windows installation is 32-bit or 64-bit, then select a driver package that explicitly supports your configuration.

1. Prepare before updating. Back up important data, especially if Windows boots from an array attached to this controller. Record the current driver version and keep a copy of the working package available in case a rollback is needed.

1. Download and extract the package. Save the driver locally and extract any compressed files. Read the included instructions for prerequisites, supported operating systems, and any controller firmware requirements.

1. Install the driver. Use the supplied installer if one is included. Otherwise, right-click the controller in Device Manager, select Update driver, choose Browse my computer for drivers, and point Windows to the extracted folder. For a fresh Windows installation, use Load driver on the disk-selection screen if the RAID virtual disk is not visible.

1. Restart and verify storage access. Reboot if prompted, then confirm that Device Manager shows no controller warning icons and that expected volumes are accessible. Do not initialize, format, or recreate an existing array simply because it is missing after an update; check driver compatibility and controller status first.
