But i cannot get the /etc/fstab entry right, on boot i get fsck errors
on the other two HDD's.
Fsck? Are you sure? :-?

Those errors can be important, can you post them?
This is expected. fsck /dev/sda will give an error since it can't find a
file system.
I can't tell (my crystal ball is out of range) so I prefer to be sure
about the nature of the errors the OP is experiencing.
Occam's razor. The lines in his /etc/fstab will create fsck errors on a normal system. No need to hunt for other problems yet.


Mount them with:

mount -t ext4 /dev/hdc1 /new-disk as an example works once the system
is up.

but the /etc/fstab example does not when i reboot.

Is it perhaps that i have the boot flag entry on the other two HDD's?
Unless you are using an old kernel (lenny or ealier releases) I would
mount the partitions by their "uuid" (or id/label/path), avoid using
the old naming system (/dev/sda1...) to ensure you are calling the
"right" device and using "uuid" will be the best option for this.

You can get the partitions "uuid" by:

ls -la /dev/disk/by-uuid/

Then adjust the "/etc/fstab" entry accordingly and verify the mount
point is already set.

Reasonable advice normally, but first I'd try to understand /etc/fstab.
Understanding "/etc/fstab" also involves using the proper device naming.

This seems to be his problem. He's put in entries without understanding
what they mean. Replacing a device name with a UUID is optional and can
be done easily once he's got his /etc/fstab working properly.
When using a modern kernel that's is more than "optional" but highly
recommended or you can end up with an unbootable system or messed mount
points.

Greetings,

Only if you are switching around HDs. You can also run into the opposite problem when changing drives and the UUID changes but the device name doesn't.
