So I have a DVD-RW that I'm using to transfer all of my pictures. I have it in the drive on the iMac and it keeps closing on me. I'll be in the middle of selecting the items I want to copy or scrolling to where the error occurred on the last attempt (didn't have any problems or errors on my HP) and the Finder will just close and take me to the user menu (music and photos, etc). This was NOT a one time thing. Happened about six or seven times before I had to leave for work. Anybody have any ideas what's going on? Any suggestions will be appreciated!
