I have an iMac with a 2TB drive. I have a 2TB WD drive used for Time Machine that is full. I would like to go to the bigest WD (type) external drive that will work with Time Machine. Is there a TB limit for TM in OS X Lion?
Welcome . I have also used a 2TB WD My Book ext HDD for Time Machine backups for the past year and have had no problems. They seem to get a very bad wrap. Perhaps we are a few of the lucky ones. The two brands recommended by macjack are very, very good brands.
