Hi all,


I purchased a new SEAGATE BACKUP PLUS 3T USB3.0 drive - and formatted GUID 1 partition - then ran repair disk and it showed with = "Error: Partition map repair failed while adjusting structures to fit current whole disk size"

And I also tried 4 partitions but no help

And I also tried formatting same on older 10.6 mac with no errors - then came back to 10.8 and error shows there...

Can some folks please try this on there own setups to see how widespread this is...


1 - ML 10.8.2

2 - Large external drive 2T or greater


Q: Has anyone experienced this and has a possible solution?
