what are your drives set to in the bios?
IDE mode or raid or what. it should not be IDE mode
also did you do AHCI?

It's set to IDE mode.  If I change this setting, will it cause any problems with XP?

I tried changing to AHCI mode.  The result was Blue Screen for both XP and W7.  Back to IDE and it's working again.

you have to do a complete reinstall for AHCI.... or suffer the lack of performance in win7 with ide mode
technically this is not supposed to work
XP i cant recall if the is a work around..

I feel reluctant to mess with my existing XP setup, which has been running smoothly with no hiccups for over a year now.  I will probably stick with it for a while longer.  I am not ready to move to W7 until I can verify that all the main software that I use works properly on that platform.  Most of it does seem to work, except for one particular plugin, the 2c-Aether Reverb.

The problem is that the driver you are loading at boot is for IDE mode, so it can't read the drive which it sees as being AHCI after the bios change. It is possible to change the mode to AHCI from IDE after installation of XP or Win7. I would make shure I had a good image of the system before I started messing with it. I suspect you would need to change both OS's to AHCI, although you might be able to kludge around that by entering the bios every time you plan to boot into XP and changing back to IDE if that is how XP is set up to run. At any rate, you should be able to see if Win7 with AHCI solves your drive problem. Remeber that you may need to install the specific motherboard AHCI controller drivers after you have managed to get Win7 to boot in AHCI mode in order to get full benefit.

FWIW, you can switch to AHCI or RAID mode (after the fact) in Win7.
Haven't found a reliable means of doing this with WinXP (we don't do much with XP at this point).

I don't think this would work.  It can access Boot Manager only when in the correct mode for W7.

By the way, thanks for the links.  I will check these out.

If it was the other way round it would suit me.  I am quite happy to reinstall W7 from scratch but I don't want to mess with the existing XP setup.

The only reason why I have been using IDE mode is that it was the default setting in the BIOS.  I am wondering why this was the case if AHCI is the recommended mode for both W7 and Vista.

I gave up on this a while back but returned to it again last weekend.  I tried disabling core parking and the problem now seems to have disappeared.  Not sure why core parking should affect harddrive activity.

Sonar now appears to be working fine in this Windows 7 64-bit setup.  However there are lots of other problems with softsynths.  I'm too busy to tackle them right now.

I have finally installed Windows 7 (64-bit) on a partition I had reserved for it when I first built the PC.  I took me a year to get round to this, as XP has been working so well that there was no real motivation for me to change.  I spent a couple of days getting all of the programs installed/registered/configured/etc., and they all work fine (aside from one particular plugin: 2c-Aether).  I have stuck with the 32-bit versions of Sonar and plugins so far.

But there is a serious problem with performance.  Any operations that involve HDD access are noticeably slow compared to the same operations running on XP.  This applies to all 3 HDDs.  Any clues?

Here is one of the faults! MatroxP690? 128mb? To bad performance even for XP

The graphics are ok.  The screen image updates smoothly with no jerkiness.  I have used similar cards with larger monitors in the past without any problems.
