Download the latest Windows drivers for AMD AHCI Compatible RAID Controller Driver. Drivers Update tool checks your computer for old drivers and update it.

Updating driver for AMD AHCI Compatible RAID Controller AMD AHCI Compatible RAID controller have limitations compared to hard disk controllers of different manufacturers. By using this controller (and especially with an older driver for AMD AHCI Compatible RAID controller), only limited hard disk information reported. However, this is not really related to Hard Disk Sentinel and completely independent from the hard disk model(s) used. The issue is caused by the current version of the driver installed for the AMD AHCI Compatible RAID controller - which blocks the detection. Alien Vs Predator Pivot Pack more. Driver versions Generally, hard disk controller drivers affect how special commands (for example the status detection) are transferred to the hard disks / SSDs and some drivers may offer less functions than others and may completely block such special commands. Hard Disk Sentinel 4.60 and newer versions show the current disk controller and its current driver version (and release date) on the Information page. This can be used to quickly verify the driver and replace it from the page if required, for example if the status of hard disks can't be detected.

Updating hard disk controller / chipset driver To improve the situation, please try to download and install the better AMD chipset and RAID driver from the section or from the webpage of the manufacturer of your motherboard. Please note that the automatic Windows driver update DO NOT work - it does not update the driver as should. Also third party driver updater tools DO NOT work as they may either do not perform the update or update to a wrong driver version. If the complete chipset installation package does not help (due to installation problems of AMD packages, this happens relative often), you may try the manual update of the driver: To update the driver manually, please download the recommended driver (3.2.1540) from the section or directly from: (for 64 bit Windows) or (for 32 bit Windows) Please download the proper package and extract to a new folder (for example: C: AMDAHCI ) and then to install, please • right click on Computer, select Properties ->Device Manager • locate 'AMD AHCI Compatible RAID Controller' device. It is located in the Storage controllers (or in some cases the IDE/ATA controllers) section. • Right click on this device, select Update Driver Software • and select 'Browse my computer for driver software' • Specify the folder C: AMDAHCI After clicking on Next, the installation begins and when completed, you will need to restart the computer, then further hard disk status information should be detected and displayed.

Then in the Device Manager, you may verify that the correct driver version installed: Information displayed with AMD AHCI Compatible RAID Controller In the best case with the recommended driver for the AMD RAID Controller, Hard Disk Sentinel displays • the complete status of all standalone (non-RAID) drives • the complete status of one hard disk from the RAID array • the model, serial number and generic status (healthy or failed) of the other disk from the RAID array. The generic health value reported for secondary (further) drives of each arrays gives only an estimate: as we only know that the hard disk did not yet reach the error-threshold, but we can't say it is perfect. This is why Hard Disk Sentinel displays 75% health (which means that the hard disk is good, but can't be sure that it's perfect) or 0% health (which means that the hard disk is about to fail). These values corresponds to the generic health displayed in AMD RaidXpert tool for the appropriate hard disk, just Hard Disk Sentinel can also show the complete hard disk status for at least one member of each RAID arrays configured. That's the maximum possible with AMD RAID Controller and it is not a bug / limitation of Hard Disk Sentinel, but a bug / limitation of the AMD RAID controller (even with the recommended 'best' driver available for that). Example: when two hard disks configured as JBOD, complete hard disk status information detected about the first hard disk in the array (FB160C4081), including health, performance, temperature, complete S.M.A.R.T. Data, lifetime statitistics and so.
