Hello,

 

I have a Dell E310 with two Seagate hard drives. One 80GB, which came pre-installed, and one 250GB, which I added.

 

It's my understanding that the drives can be run in SATA mode without having to set up a RAID volume. They're currently running in PATA (IDE) mode. It states in my user manual that in the BIOS I can set the SATA controller to any one of the following three modes-

 

1. RAID Autodetect/AHCI

2. RAID Autodetect/ATA

3. RAID on.

 

I only have the second two options.

The first one, RAID Autodetect/AHCI, is not available.

 

Does this mean I can't run my SATA drives in SATA mode? And if not, why not? The drives support it, and the chipset supports it. Doesn't the BIOS support it?

 

Am I missing something?
