I have a question concerning an aspire 6920. I attempted to change os's from vista back to xp pro. I wiped the hard drive (250g) with advanced killdisk. 3 pass. Finished without incident. I then restarted the system with xp pro corp sp3 and it said it couldnt find the hard drive. I closed setup and ran acronis disk director only to find that it too couldn't "see" the hd. I removed the cd rom rebooted and went into cmos and returned it to defaults. Restart with os install disk again, no hd again.
Am I missing something?

Was the CD drive the first boot device in the BIOS?

Hi i think your problem lies with yor hard drive controler

1. go in to your bios genraly F1, F2, DEL

2. depending on the bios make locate to something called "Advanced BIOS Configuration"

3. look for a key that says "Hard Drive/IDE Configuration" < will prob be diffrent but along those lines

4. Change the setting to "Compatability or AUTO" as it is proably set to "AHCI" which is why xp is not seeing your drive

Hope this helps

Is the hard drive reflected properly in the BIOS?

The default setting for some BIOSes...is not the hard drive, but possibly the floppy or some other boot source...so, as Mark suggested, I would check that.

As far as I know, this is a common problem. XP doesn't have Serial ATA drivers for seeing your hard drive(s). Maybe they fixed this in SP3, but it's certainly an issue for older versions of XP. And some BIOS's actually have to be downgraded to support XP because their manufacterers are pushing for Vista too. It really sucks.

I think the easiest fix for this would be a BIOS setting. But the settings for the BIOS are not standardized and are (to me, at least) very confusing.

When attempting to install XP, you'll see a prompt at the bottom of the screen to press F6 to install SCSI/RAID drivers. This is where you install the SATA drivers. Unfortunately, XP can only see these drivers 2 ways:
1 ) a floppy drive
2 ) slipstreaming the drivers into the XP installation CD

I prefer the floppy drive method (because most SATA drivers come with a utility to put them on a floppy) - and I use a USB floppy drive to install them.
