Help... Not only did my MBP hard drive just stop working, but I needed to get the files off of my time machine backup on my other mac. My other mac was running very slow so I upgraded it to SL. After I upgraded, I plugged my 1TB WD hard drive into it and it does not recognize the hard drive. It worked find before I did the upgrade. So I borrowed my neighbors mac and plugged my time machine into her laptop running straight leapord and it also failed to mount. It is almost like plugging it into the computer with SL unmounted the disk inside the casing. It happened to both of my time machine backup drives.. Help. If I can not get these drives to work, I have lost 2 years worth of data that I backed up in two places. Has anyone else had a similar problem. Any help would be great.
