Optical Bay Hard Drive caddy not recgonized, system hanging/not booting

Replaced the optical drive of my laptop (Dell Inspiron 1464) with a hard drive caddy to extend the storage capacity, but the BIOS seems could not recognize it.

After some digging and checking, I noticed that the SATA port in the laptop for the optical drive is only 1st gen (150MB/s), and it does not support the SATA II type (300MB/s). So I changed the mode of the dard drive into SATA mode with copper wire (jumper settings, to change the working mode), and it works perfect.
