750gb is the largest EHD that Dish officially claims to support. So, it is believed that is the largest drive they have put thru QA testing. However, many others have said they use 1tb drives with no problems.
Did you try a power cord reset on the receiver and on the drive? Back in the early days of EHD support it would sometimes want to format the drive but if you did a hard reset everything would come back. Not sure that would have helped or not, but I sure would have tried it before reformatting the drive.
