I bought both a TT BlacX and a 1.5 TB WD Caviar Green hard drive to go with it. From day 1, the WD had trouble mounting on my MacBook Pro (10.6.2). If I put my other drive in, a Seagate 320GB 7200.10, it mounts pretty much straight away. Any ideas what I'm doing wrong? I've tried it on my bootcamp partition on my MacBook, and it also had trouble mounting. I can see the JMicron USB mass storage device under System Profiler, but it doesn't mount. Thanks!
