Troubleshooting ASUS AMD SATA AHCI Controller Driver Issues in ESXi 5.5

When upgrading to ESXi 5.5, many users encountered issues with their SATA controllers, which were previously supported by the generic AHCI driver in earlier versions of ESXi. One of the affected parties is ASUS, whose AMD-based SATA controllers stopped receiving driver support after the update.

The problem could be easily solved for network interface cards (NICs) by using the old ESXi 5.1 drivers with ESXi 5.5. However, until recently, there was no known solution to fix the issue for SATA controllers.

To troubleshoot this issue, it's essential to first check if Windows Update has any available updates for your device. You can do this by selecting the Start button and then going to Settings > Update & security > Windows Update. Select Check for updates to scan for new updates.

Additionally, you can use the HP Support Assistant tool to search for the latest drivers for your Notebook. To do so, click on My devices in the top menu and then click Updates in the My PC or My notebook pane. Finally, click Check for updates and messages to scan for new updates.

For ASUS users specifically, it's worth noting that their AMD-based SATA controllers were not included in the HCL (Hardware Compatibility List) but worked fine with the generic AHCI driver in earlier versions of ESXi. Unfortunately, this support was discontinued in ESXi 5.5.

In conclusion, if you're experiencing issues with your ASUS AMD SATA AHCI controller driver after upgrading to ESXi 5.5, try using the old ESXi 5.1 drivers or check for updates through Windows Update and the HP Support Assistant tool.
