What's the output of:
That should list your partitions.
If it doesn't display all the information you're expecting try:
Code:
fdisk -l /dev/hda
fdisk -l /dev/hdb
fdisk -l /dev/hdc
fdisk -l /dev/hdd
Also, depending on how you partitioned (from what I understand the partition was used by Linux when you changed the size and added another), you may have lost data.
