10.10 can't detect SATA drives

[Tsu Dho Nimh]

Just what the title says ... I'm trying to install Ubuntu 10.10 and it does not detect either 300G SATA drive in my system. One of them is /home for my non-OS software and the other is used for data storage.

It does detect the drive (SDC) where I have 9.04 installed, but /home is on one of the SATA drives.

Where to start? 9.04 works just fine, but I'm running tio problems with FLASH web sites insisting I have to upgrade Flash and Adobe doesn't have anything for 9.04.

In your BIOS, find the SATA channel, and change the "mode" to "legacy" or "IDE" or "compatibility" or whatever it offers, NOT AHCI.

Then try your installer again.

After you have installed Ubuntu, then you should be able to go into BIOS again and change the SATA mode back to AHCI, and it should work.

BIOS does not have a channel called "Legacy" or "IDE" for SATA.

My choices are SATA, SATA, and AHCI.

Any ideas?
