Disk Doesn't Contain A Valid Partition Table

I am unable to mount the 2nd disk's extended partition. Please help.

Commands I tried and returns....

Quote:

mount -t ext2 /dev/hdd2 /second
mount: wrong fs type, bad option, bad superblock on /dev/hdd2,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Also I tried to add it to /etc/fstab but it says the same error, Disk /dev/hdd2 doesn't contain a valid partition table... I am able to mount /dev/hdd1 successfully.
