Hi all, I have an i7 27 iMac with Lion 64bit and this docking station I use quite few different HDs with this dock and it works fine. Suddenly one of my HDs (the most important one ) became very slow from one minute to the other. I was copying a large video file and for no obvious reason it became slow and then it unmount. I stop it for a few minutes and tried once more only this time I got a message that this disk is not recognized and needs to be initialized before using it. I also tried this on a Win7 laptop with MacDrive on it and I get the same message from the OS. You need to format before using it. This HD is very important for me and even that I do have most of the files on other drive I do need about 35GB out of it. You see it happened when I was trying to backup this new data so I never got the chance to complete the copy Do you have any idea how I can restore the data?
