I have a Dell Alienware PC here.

Bootable diagnostic utilities do not recognise presence of disk because in the BIOS
AHCI mode is set AND there is no option to change it back to IDE mode.

How do I run diagnostics on it's HDD?

AHCI mode is set AND there is no option to change it back to IDE mode.

Is there an option to set AHCI to Compatibility Mode?  If so, that should work.

If you are not able to change the AHCI to IDE Compatible mode then I would suggest that you slave the drive to another PC and perform there scan with your Diagnostics tool in Windows. Every HDD vendor provides a Windows and DOS based diagnostics tools.

Those diagnostics I have used up to now have never had any issue with AHCI mode. You only start to get issues when you try to start or install an OS like Windows. Are you sure the disk is even recognized by the BIOS? If the BIOS doesn't recognize the disk, no utility will either. Are you trying to run the correct utility? If you run the utility of the wrong disk manufacturer on a disk, it usually won't recognize the disk either, or it will recognize it, but refuse to diagnoze it. What diagnostic are you trying to run?

Look very carefully in the BIOS ... it's almost certain that there will be a way to change the SATA mode.    It may not say "IDE" ... it may be a "RAID Mode" setting with Disabled, RAID, and AHCI options or something along those lines -- setting it to Disabled will enabled IDE mode access.

Be sure to look carefully at the various submenus -- some of these settings can be hard to find, depending on the BIOS structure.    But I'd be very surprised if an Alienware system doesn't have that option.

As suggested by Gary, I dug very deep in the BIOS and "IDE" "compatibility" "RAID" or any other mode that might suggest an alternative to AHCI  was nowhere to be found.

Nobus, it was an Alienware X51.

I ended up slaving the hdd to another PC to run diagnostics.

HDD manufacturers should really offer a bootable diagnostic that can be used in AHCI mode!

Thanks guys for all your help.
