esata external hard drive througn 2nd hard drive caddy
I bought a esata-sata cable and tried to connect a esata external hard drive througn a sata 2nd hard drive caddy. The result is that my T42 can not detect the external hard drive. The caddy, cable, and the external hard drive are all functional with other setups. As I know, the signal of esata and sata are the same. It should be just passing through. I don't understand why it fails. I observed that both the leds on the caddy and above the caddy are lighting when I boots T42. However, both leds dims after that. Any suggestion?
PS. I know using a pcmcia will be easier. However, several reviews confirmed that the writing speed is limited to 30 MB/s through pcmcia. The writing speed on the caddy is at least 55 MB/s when I tested it with a 2.5 in hard drive.
