Bug Description

When I load up the live CD, enable all standard repositories run:
sudo apt-get install dmraid
sudo modprobe dm-mod
sudo dmraid -ay
sudo dmraid -r

I can then mount my drives using something like:
sudo mkdir /media/Windows
sudo mount -t ntfs-3g /dev/mapper/nvidia_ebgeeceg1 /media/Windows

just as I could with the Hardy installation. In Hardy gparted could see these RAID 0 partitions but in Intrepid the partition editor doesn't even start if using the installation utility and if I fire up gparted directly, it just shows /dev/sda, /dev/sdb and /dev/sdc.

I've updated to the latest libparted1.8.9 also to no avail. I've attached partman logging from /var/log/syslog that seems to continually cycle since the first attempt to install. At the end of dmesg I see:
[ 242.672009] device-mapper: uevent: version 1.0.3
[ 242.673782] device-mapper: ioctl: 4.14.0-ioctl (2008-04-23) initialised: <email address hidden>
[ 324.397426] JFS: nTxBlock = 8006, nTxLock = 64052
[ 324.710688] SGI XFS with ACLs, security attributes, realtime, large block/inode numbers, no debug enabled
[ 324.715008] SGI XFS Quota Management subsystem
[ 324.901007] program parted_devices is using a deprecated SCSI ioctl, please convert it to SG_IO
[ 1701.842819] program parted_devices is using a deprecated SCSI ioctl, please convert it to SG_IO

I.e. I can't install Intrepid on my computer cause I use RAID 0, whereas I could install Gutsy and Hardy.

Note that the installer on the live CD explicitly doesn't support RAID yet, although it's on the roadmap. However, you clearly managed to work around this somehow, and we should certainly fix gparted. Working on it.
