Lightroom 3 Metadata Error when Editing Image
I am working with Adobe Photoshop Lightroom 3 without having any problems. But when I am making any changes in the image, an error message is coming which says that ‘An unknown error occurred when writing metadata to this picture. Do you want to retry?’ It gives me three options such as Retry Metadata Export, Cancel and Import settings. If I select the ‘Retry Metadata Export’ it says ‘It is not able to write metadata because the drive space is less than 1GB. The original picture is saved in external drive and imported to Lightroom.  I don’t know why this is happening. Are they asking for a hard disk space or Lightroom space? I have tried by removing the folder from the Lightroom, but there was no change in the result. If anybody knows why this is happening, please help me.
