copying files failed. the disk could not be read from or written to.
Im moving my iTunes to an external hard drive. Its moved about half already and Im now getting this error. I have no idea what file its getting stuck on so I cant remove that file. When I restart it it will say preparing to copy then I get the error right away. I dont want to delete the extrenal and start over if I dont have to.
iMac, OS X Mountain Lion (10.8.4)
