Re: Ubuntu installation fail detect 1TB HDD's partitions
Hi and welcome. There are some possibilities. Has that 1TB drive ever been used in a RAID array? The Ubuntu installer will not even see a drive that has Windows RAID signatures on it, although it ought to.
Try booting the live CD and "trying without installing"
Open a terminal and run
sudo sfdisk -luS
You should find that this lists all your drives and partitions and gives them names of the form sdxy. Windows drive names like C: and D: are meaningless to linux. Please post the output.
sudo dmraid -r
and this will list any Windows RAID devices detected.
To erase the RAID signature (or super-block) on drive /dev/sdx (x=drive letter for 1TB drive)
sudo dmraid -E -r /dev/sdx
