Hi All,

 

I am trying to format a 3TB WD Elements (USB 2) external HD, GUID, 1 Partition Mac Extended Journaled. The formatting goes ok.

If I click on the "3TB WD Ext HDD 1021 Media" on the left in Disk Utility and hit "verify disk", I get the following error message:

 

"the partition map needs to be repaired because there's a problem with the EFI system partition's file system"

A 'repair disk' goes through without hitch, but if I hit 'verify disk' again, I get the same error.

 

I wonder if I can just disregard this or if I will encounter problems somewhere down the line.

 

 

Thank you very much for your help.

 

 

(Verify of the actual partition does not yield any problems)
