hard drives not detected.

[mafia_emu]

Trying to install Karmic (x64) and it will the partitioner will only detect one out of four of my hard disks.
It can mount all my hard disks on the live cd. So why can't the partitioner see them.
Is there another way I can go about installing.
All help greatly appreciated.

I have a similar problem. I have stripped the PC back to a single CD drive and a single sata drive. I boot up on the Cd image, Parted running on its own can see the sata drive, but when it comes up during the 9.10 install phase the drive is not detected.

I know the sata drive is ok, I have installed 9.04 on it without difficulty.
I have also run the WD Diagnostics programs on it and it passes with flying colours. I have also tried it on a different sata port!

The other three drives I have on the PC are detected correctly, one which is the original system drive.(I want to do a fresh install on a clean drive and import all the bits and bobs over from the older system drive!).
I could use one of these drives.

But that is not the point.

Why does this drive not work?

BTW its a Western Digital WD2500KS model

Is this a common issue? Am I wasting my time?

May have something to do with this, looks like it is being picked up as part of a Raid array. How do I boot with nodmraid option?

F6 set to nodmraid.

I will let you know if it succeeds.

Hi there!
I went through all this yesterday - reading through the forum, it looks like a common problem. Indeed, before the official release, this disk recognition issue was flagged repeatedly, but they (Canonical) did nothing about it.
Apparently, they have a laudable, but flawed, policy of sticking to release dates come what may. Of course, if they discover a problem late in the day, they feel they still have to release it even if it doesn't work!
I'm going to wait a week or two, and if it isn't fixed I'll have to go elsewhere.
This is sad, as I was really looking forward to this, to replace Vista.
