I have a korg i4s do not have the manual can you tell me how to record a backing track on it and is there any site I can go to to download the i4s manual

I will assume you want to sync the two as one. I have one of these sitting in a closet. The 3200 will record 12 tracks at a time if I remember correctly. I believe the Korg will sync to Midi Time code. I just wonder if the midi implementation allows for start and stop code. Anyway, I found this information:
x2. MIDI messages used by the D3200 Note On (Note, velocity), aftertouch, pitch-bend:
The D3200 uses these messages to control effects.
Program change:
The D3200 uses these messages to switch scenes.
Control change:
The D3200 uses these messages to control mixer and
effect parameters.
MMC (MIDI Machine Control):
MMC messages can be transmitted from the D3200 to control an external MMC-compatible sequencer or recorder. MMC messages received from an external sequencer or recorder can be used to control the D3200.
MTC (MIDI Time Code):
The D3200 can transmit or receive MTC messages to
synchronize with an external sequencer or recorder.
MIDI Clock:
The D3200 can transmit MIDI Clock. It can also receive MIDI Clock if you have selected MIDI Clock for the tempo track and are recording the tempo track.

6. Playback
(1) Set channel 1 to play.Turn the REC/PLAY key on. Then press the channel key of track 1 (the track you just recorded) to set it to Play (key lit green).
(2) Return to the beginning of the song.Hold down the STOP key and press the REW key to return to the beginning of the song (?p.37 "2. Location").

Give your email, I'll send for free.

Are you connecting to the laptop and using it as a midi controller? You can record midi notes from the keyboard and send them to your laptop via USB using any midi sequencer program (reason, logic, etc). Create a midi track, select the input of that track as your keyboard, then hit record to play some midi notes. To hear what you record, you have to set the output of the midi track to whatever midi sounds or instrunents you have installed on your laptop.

If you are trying to record the actual audio sound the keyboard makes, use an audio program such as cubase, sonar, audacity, pro-tools, and either mic the keyboard, or connect one of the other audio outputs (1/4" TRS) to an audio input on your DAW, and record an audio track that way (as opposed to a midi track).

Here is a link to the manual on Korg's site.

Good Luck!

First thing would be to check the power supply voltages. It may be the disk drive is failing. Drives are inexpensive, might be worth a try with a new drive. Also check that cables to the drive have not been loosend by handling.

check to see if your in monitor mode, seems like yout not

It depends on whether you are trying to record audio or midi Which are two different formats and have separate connections. I will have to download the manuals for the keyboard and the recorder and read through them but I will try and help you if you would like.
