I was referred here by a friend that was helped out with an issue on his machine and I am hoping that I can get the same. I bought a maxtor 1tb external drive about a month ago. Since I loaded it up with music, backed up files from work and have many personal files that have transferred with me through the ages from computer to computer. Shortly after putting these files on there I started getting COOD11B1 errors anytime itunes, winamp, wmp or any such program tried to play my music. I researched this on the net and found several people claiming how to fix the issue. So far nothing has worked. I cleaned out some registry files, downloaded codec packs, scanned the drive for errors and etc. It seems all the talk is with wmp11 being the problem but I am not convinced. Now all of a sudden I am getting an I/O error anytime I try to access anything on the drive. Please help this is driving me nuts and I find it hard to believe that a new hard drive went bad so fast.
