Ubuntu Installation :: Missing Hard Drive During Setup?

I've managed to get a hold of a 160GB drive, which I hope to use as my system drive for a server that I'm setting up. This may be the tip of the iceberg (as it tends to be with me for some reason), but this is what's happening:

I got the drive, which has been used before but has been secure erased, and it's been sea tool-ed so is therefore as good as new. It shows up fine in the BIOS, and GParted discovers it straight away. I then split it into 3 partitions:

A ~10GB system partition - sdd1
A ~130GB storage partition - sdd2
A ~4GB swap partition - sdd3

GParted performs all actions straight away with no issues.

After partitioning, fdisk -l reports the following:

Code:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x2bd2c32a

[Code]....

I've then gone to install Ubuntu. I go through all the major steps, up to where it asks you where you want to install Ubuntu... at which point sdd just doesn't show up at all. It shows sda, sdb and sdc fine, but sdd is nowhere to be seen.

Two things strike me as odd (although I suppose understandable) - Firstly, every partition in sdd mounts fine, but is owned by root. Secondly, each partition has a folder called 'lost+found' with varying amounts of data. There's 662.3MB in the 10GB partition's lost+found folder, and 6.9GB in the 130GB's folder.
