The -x means "stay in this filesystem", so I think cp -ax will do the trick. It'll copy symlinks as symlinks - it should make your new filesystem identical to the old - permissions, everything.

and it doesnt work !
what I did :
partition the new HD with the same FS as the old one
create new partitions with fdisk
old disk
| Quote: | grenada ~ # fdisk /dev/hda
The number of cylinders for this disk is set to 1245.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/hda: 10.2 GB, 10248118272 bytes
255 heads, 63 sectors/track, 1245 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 1 7 56196 83 Linux
/dev/hda2 8 70 506047+ 82 Linux swap / Solaris
/dev/hda3 71 1245 9438187+ 83 Linux
Command (m for help):

new disk grenada ~ # fdisk /dev/hdb

the new partitions arent exactly the same size as the old ones - all a bit bigger, icouldnt get it to partition them to exactly the same size
I then dd copied existing -> new
as the new hdb3 is smaller than the old hda3 I cp -ax'd the files across.( dd runs out of space !)
ive reset the jumper on the new HD to master, disconnected the old one, plugged the cable into the new HD and on boting it the BIOS doesnt detect it.
however, when its mounted as a slave its detected by dmesg
| Code: | grenada ~ # dmesg |grep hdb
ide0: BM-DMA at 0xe000-0xe007, BIOS settings: hda:DMA, hdb:DMA
hdb: WDC AC28400R, ATA DISK drive
hdb: max request size: 128KiB
hdb: 16514064 sectors (8455 MB) w/512KiB Cache, CHS=16383/16/63, UDMA(33)
hdb: cache flushes not supported
hdb: hdb1 hdb2 hdb3
grenada ~ #

so what has gone wrong ?

Do you mean the BIOS can't see it at all, or just can't boot from it? If it can see it, but not boot from it, the most likely reason is that you haven't copied the MBR across, or run grub/lilo/... on the new disc?

the bios doesn't detect it and thinks there is no HD
But just dd'ing the boot partition should have copied over grub etc (shouldn't it) ?

Yes & no 
Yes it copies over the settings, but you still have to make the MBR boot the setup.
Did you install grub to the MBR first time, or to the install partition?
