ssd1-ssd5 are the partitions on that disk, not the entire disk. Listing your current disk layout is like this: fdisk -l /dev/sdd

You'll see immediately where your 72G went in partitions.


If you want to erase the disk and use it as a whole you can use fdisk or cfdisk on it and format it after.
fdisk /dev/sdd
(delete all partitions with 'd' and create a single new one with 'n' and format it)
mkfs -t ext3 /dev/sdd1
mount /dev/sdd1 /ora_dir
(be sure to add it to /etc/fstab like this as well if you want the disk to be mounted after reboots: /dev/sdd1 /ora_dir ext3 defaults 0 2)
