I formated a new 1.5TB WD hard drive, using the eSATA cable - in the FAT32 format so I can use it on my PC as well. (It was formatted on the MAC) I was working on the Hard Drive via eSATA and the express card. Then the Hard Drive was accidentally unplugged. Subsequently, my MacBook Pro didn't like that and gave the warning message to properly eject ... too late! I restarted the MAC and it still won't recognize it - I've tried eSATA, USB, firewire- and nothing. The hard drive was all 3 connections. So, I tested the HD on a friend's MacBook Pro and the hard drive is recognized without any hesitation and it works fine. So, there is nothing wrong with the Hard Drive - its my MacBook that won't recognize it. The HD won't even show up in disk utility of my MAC. I've restarted many many times and I've tried every port available. Any suggestions??? Thank you!!!
