If indeed it is 40 wire, you need to switch it to 80 wire. It doesn't matter if "new" or not, they don't wear out. By now used 80 wire cables should be abundant.
40 wire cables look like http://upload.wikimedia.org/wikipedia/commons/thumb/a/a4/Nappe.svg/550px-Nap... and like MFM/RLL, floppy and 50 pin SCSI cables, with 40 individual wires readily counted by people with normal eyes. Usually their connectors are black, at least on the older ones. Moderate bends in them usually are not remembered.
80 wire cables have a smaller wire size that is difficult to count by average eyes. They also have blue and gray connectors instead of black. Bends are usually remembered unless very mild.
Note that there are two types of each, regular, and cable select. Each HD must be jumpered according to which type is used. Cable select cables have one wire that is null, and often can be distinguished by a hole in it near one end. It may or may not have the words CS or cable select stenciled on it.
#hwinfo shows ribbon-connect hard-disk as :
Device Files: /dev/sda, /dev/disk/by-id/ata-ST3320620A_9QF7G56W, /dev/disk/by-id/scsi-SATA_ST3320620A_9QF7G56W, /dev/disk/by-path/pci-0000:00:1f.1-scsi-0:0:1:0
That would be much too new for optimal use with a 40 wire cable. --
