Partition map problem with my hard-drive

I have a 1 TB G-Drive back up drive.....it has developed a problem...... I have it physically connected, and the drive is on........the computer recognizes this connection.....when I went to troubleshoot the drive, I found this error message on disk utility as I clicked "Repair Disk".........as follows, " Partition map repair failed while adjusting structures to fit current whole disk size." What does this mean and how do I repair it, if possible? I don't want to loose the information on the drive..

iMac, OS X Yosemite (10.10)

To fix it you are probably going to have to erase the drive and reformat it. This will erase all data though.

You are welcome. Buy another drive and copy the information to it. Then you can use both drives as backup drives, since hard drives do fail as you have just experienced.
