If you have the hardware to support the following then try:

Create an LVM with the smaller drives if you have enough for 160+ Gb

dd the failing drive assuming it is seen in /dev (this example assumes 
sdc) and assume your lvm partition mount is lvm1

    dd if=/dev/sdc of=lvm1/recovery.img bs=512

also do some research on ddrescue which is geared more towards this type 
of recovery.  James also pointed out checking for hardware failure which 
is a good point.
