Hi all I have reported this problem to Yamaha 4-5 months ago-went thru 3 new internal Hard Drives and another brand new T4 keyboard all to no avail-dealt directly with Steve Demming at Yamaha USA.

This problem has nothing to do with fragmentation or over 50% full Hard Drive--it has been experienced by T4 owners all over the World both on playback of MP3's and recording using the Audio/Recorder/Player.

I encourage all experiencing this problem and believe me if you record much using this function or play MP3's you will see this issue at some point-to Please Contact Yamaha directly and do not I repeat do not accept the answer to Defragment or Reformat as this will not correct this problem.

I now feel that Yamaha is totally dragging their feet on this problem!!!!

Great Day

Jack Hanoka
