I was unable to do anything with that drive. The problem was that when the new drive was connected to the Linkstation, I was unable to get to the disk management settings in the Linkstation software. The page would be blank. I updated the firmware, reset the linkstation, but I still was unable to do so. When I attached the old drive, the disk management 'folder' was available again. I called buffalo and the guy said that there may be a limitation with the size of the drives attached to the linkstation. I have searched everywhere and have not been able to find any information on USB drive size limits. Hence the question. If there is no drive size limitation, where is my problem?
