Hi,

I have a HP workstation xw4200 with a SATA controller that can be configured as a stand-alone SATA controller (no RAID) or in full f/w RAID 0, 1 or ... mode. In my configuration it is set up in a RAID 1 mode, presenting the two 160 GB disks as one mirrored set.
Windows installation detected only one disk, being the mirrored volume. Installation of Windows succeeded. Windows presents the RAID controller as a standard disk (such as IDE) and did not require specific drivers to be installed.

Now I want to copy information I put aside back to this RAID volume, using knoppix.
Problem is knoppix only reports the two individual disks, not the RAID volume.
I can see the RAID set but the status says "RAID is not available".

fdisk -l only lists the individual disks, not the RAID set.
My question: what can I do to mount this RAID volume?

Thanks for any information that could help,

Pat

Open Synaptic package manager and search for dmraid. Then see here: http://wiki.debian.org/DebianInstaller/SataRaid.

YMMV

But the documentation you pointed to says SATA Raid or software raid. I don't have the hardware, and have not played with the hardware, but the original poster says he has sata hardware raid .....

I meant to point the OP in the direction of dmraid, and also mdadm (http://linux.die.net/man/8/mdadm). The link I posted states:
The RAID support offered by most Serial ATA disk controllers is not hardware RAID. Instead it can best be classified as "software RAID provided by the BIOS of the controller".I dont have the hardware either, and as it turns out the 6.0.1 version of Knoppix has dmraid and mdadm installed, so hopefully the OP can give them a try without downloading anything.

What kind of SATA controller is actually responsible for the array? It doesn't sound like an "actual" array (e.g. hardware RAID), so you'll probably have to re-setup the RAID using mdadm when using Knoppix.
