The disk-drive has two major components: the circuit-board, and the 'spinning' part. If the electronics on the circuit-board have failed, you would get the 'not present' message. But, since you connected the disk-drive to a different computer, the circuit-board is OK. Caution - On servers equipped with an Adaptec disk controller, all drives must be part of a volume before they can be used by the BIOS or the OS.Adaptec controllers support single-drive volumes that can be used for drives that are not part of a RAID array.

• A bad hard drive cable. If the recommendations above are attempted, and you are still encountering the same issue, the cable connecting the hard drive may be bad. Replace this cable with a known good cable. If you continue to experience the same issues, the hard drive may be bad. We recommend the drive be replaced.
• There might be an instance, wherein the drive gets corrupt or format while enabling the disk controller in BIOS. Therefore, to resolve all such issues, one can use Computer Data Recovery Software. It is a simple and reliable solution, which helps to recover all deleted files from the HDD.

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.

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 Driver Zone 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 Driver Zone 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 Driver Zone section or directly from:
https://www.hdsentinel.com/driver/amd_raid_3.2.1540.92.zip (for 64 bit Windows) or
https://www.hdsentinel.com/driver/amd_raid_x86_3.3.1540.22.zip (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.

C-media Hard Disk Controller Driver

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. In contrast the secondary hard disk (Seagate ST9320421AS) provides only this generic status - 75% health but with no further details.

No improvement made by AMD for years

The problem is that even if we (both developers and thousands of users) asked them in the years, they seem advance in the wrong direction as newer drivers even offer LESS functions (they even removed the ability to detect any, even generic status of the secondary drives).

We can just hope that one day AMD will change their mind and hear the requirements of users. AMD: we want to monitor the complete status of ALL hard disks / SSDs configured as RAID arrays and you should release a new driver which allows this. Wonder why AMD still does not allow this - as complete hard disk monitoring is possible with dozens of RAID controllers from all major manufacturers by Hard Disk Sentinel (listed at Compatible hard disk controllers, RAID controllers section, so have no idea why their users are not important for AMD, why they ignore our requirements.

Note: newer Windows operating systems may automatically have driver version 3.6 or 3.7 installed as default. The numbers are confusing as they may indicate the driver is newer - but it is actually older and worse than the recommended driver. These 3.6 and 3.7 versions do not provide access to any hard disk status information. Upgrading the driver of the AMD AHCI Compatible RAID controller to the recommended 3.2.1540.92 version helps in such situations.

Alternative solution

In the worst case, you may try to install the 'Standard AHCI 1.0 Serial ATA Controller' driver. This is a built-in driver in Windows so there is no need to manually download and extract. When standalone, non-RAID configuration used, it can work correctly for the AMD controller.

To install this driver, proceed the above mentioned installation steps

• 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

• Browse my computer for driver software

• Then select 'Let me pick from a list of device drivers on my computer', and if required, enable the 'show compatible hardware' option - and then Windows should show the 'Standard AHCI controller' driver also as an option.

Driver Zone

We recommend to use the following drivers for the respective hard disk controller, RAID controller, motherboard chipset or listed hardware device. These may be not the most recent versions of the drivers, but they were tested either by us or reported by most users as actually working, meaning that they do allow getting complete hard disk status information and they do enable important disk features, as e.g. TRIM on SSD drives. Different versions from the ones listed here _might_ work on your system, but usually they have been found to be quite buggy and therefore we do not recommend their use.

The following drivers are tested and recommended to use for the appropriate hard disk controller, RAID controller, motherboard chipset or related hardware device to get complete hard disk status information:

Note that all hard disk controllers provide hard disk status information in single/standalone mode only unless RAID mode is listed for the appropriate hard disk controller (RAID controller).

Note: the firmware update for ASMedia ASM1051 USB3.0 bridge may work with enclosures, adapters based on this chip to get the missing status information. Not recommended for SIIG JU-SA0212-S1 as the device does not work with the new firmware.

Please check back for new, updated, tested and verified drivers for different disk controllers.

C-media Hard Disk Controller Drivers

In some situations, the newest (most recent) drivers may not be working correctly, in this case the updated version is not listed and you should select a driver from this list.
