Is there any reason why the combination of a Macally G-S350SUA sata HDD enclosure and a Segate Barracuda ST31000340AS would not work together? Besides the HD not mounting? the enclosure has external power which works when I turn the combination on I can hear the drive turning itself over and over trying to mount. I am using a firwire connection. The drive doesn't show up in disk utility either. I also tried jumper settings at both 1.5 and 3 Gb/s neither worked.
