In another thread (http://www.steinberg.net/forums/viewtopic.php?f=196&t=46699&start=50), there was a discussion about crashes that could occur when closing the C7 MixConsole and I posted an example of it. From which, Fabio Bartolini (a Steinberg support crew member) interviened, asking me to send him the C7 crash dump file. After a discussion via PM, he also asked me for a complete description of my system, using an .nfo file generated by MSInfo32.exe, the Windows system configuration viewer. So, I also did, via e-mail.
The problem is that, using this tool, I stumbled upon the fact that my 2 HDDs were in IDE mode, not AHCI. So, I made few researches on internet which clearly showed that using AHCI is better, especially for intense read/write applications such as audio ones. The disk data transfer rates are reported to be diminished from 10 to 20% and there are much less strain for the disks themselves, due to the way the controller manage the heads movements of them, hence a life duration increased.
So, I realize that I forgot to check this point in the BIOS of my system before installing Windows 7 three years ago on it… Added researches gave me the way to set my controller in AHCI mode in a safe way (it’s a sensible operation : any error can lead to a system refusing to boot…) :
There is a key in the registry to change, and AHCI drivers to install if they are not present. I found, on a Microsoft support page (http://support.microsoft.com/kb/922976/en-us) a patch (MicrosoftFixit50470.msi) doing all this in one pass. Downloaded and installed it. I checked afterward and, indeed, the involved registry key has been modified as it should.
Restarted my system and immediatly went in the BIOS to set my HDD controller to AHCI. Crossed my fingers, rebooted and immediatly stumbled on the following message (before Windows start) :
SATA drive 1 - ATAPI not compatible
Press F1 to resume
Which I did… And everything was normal afterward. Phew ! But since, each time I reboot, I get this message. Of course, I checked how my CD/DVD-ROM drive behaves and everything seems to work : I can copy files from an inserted DVD-ROM and play songs from an audio CD. Didn’t try to burn something, though… FWIW, this drive is a SATA one, labelled as ‘TSSTCorp CDDVDW SH-S223C ATA Device’ (Samsung) and reported to work normally in Windows peripheral manager.
So, after all this, the question is : why does the BIOS keep on displaying this message and how to get rid of it ?
Thanks for any suggestion.
