R-09HR: SYMPTOM: The Computer Does Not Recognize the R-09HR

The following is information to help you troubleshoot in the event that a computer does not recognize the Roland recorder:

  1. Be sure that a compatible SD card is being used:

  2. Try a different USB port on the computer and/or a different USB cable--just to be sure that one of these is not the cause.
    Note: Do not connect the recorder to a USB hub while troubleshooting.
  3. Be sure that you are connecting to a USB 2.0 port on your computer; or a USB 3.0 port with backwards compatibility. Check the USB 3.0 specifications of your computer to determine if there is complete support for USB backwards compatibility.
  4. Physically disconnect any connected power supply and test with new, unused Alkaline or Nickel Hydrogen batteries.
    Note: Lithium batteries are not compatible with the recorder.
  5. Be sure that a PSB-6U or UDC-25 power supply is being used only--3rd party power supplies can cause the unit to not operate properly.
  6. Be sure to log onto your computer as a user with administrative privileges.
  7. Close/turn off system monitoring/anti-virus software temporarily--this may be preventing your computer from recognizing the recorder. 
  8. You may have a fragmented memory card--due to improper ejection from a computer, power loss while recording, not formatting a new SD card, etc. We would recommend formatting the SD card to alleviate the possible fragmentation on the card:

    NOTE: Formatting a memory card will delete all contents on the card.
  9. Try using a different SD memory card (if one is available) to rule out a malfunctioning card.
  10. Test on a different computer (if available) to rule out a computer related issue.
  11. Be sure that your recorder's system version is up to date. The recorder's current version appears on the display when powering on the unit. The latest version may be downloaded below:
