WavManager V2.12 works with Windows XP. Go to the FostexInternational site, Support and WavManager software. Download both the Wavmanager software and the .pdf file of instructions. WavManager makes the MR16 look like an external drive to your PC.
Try to download the songs you want to keep on to your PC. Then try to re-format the disk.
If this fails and the MR16 is locked up and will not do anything. Try the following:-
1) Connect the AC cable and power on MR16. After the bootup procedure
is completed, the display on the right will appear on the MR16
LCD.
2) Press the [MENU/ENTER] dial while holding down the [STOP]
and [POWER] keys. If you do so, "Service Mode" is displayed on
the MR16 LCD.
CAUTION: If the [POWER] key is held down for more than three
seconds, MR16 turns off. Please be careful to expedite
the above manipulation 2).
3) Rotate the [MENU/ENTER] dial and select “Service Mode”. Then,
press the [MENU/ENTER] dial. You can see that the following service
menus will appear on the MR16 LCD.
Select one of the service menus you would like to execute and press
the [MENU/ENTER] dial. In this case Advanced Format.
Advanced Format
MR16 checks the remaining capacity / partition information written on the
internal HD in the bootup process after powering on. In case this information
does not match the current HD condition, the “Advanced Format”
service menu can be used. For example, even if no song has been created
(recorded) but the remaining capacity indicates only 10MB, execute the
“Advanced Format” menu.
As indicated on the right, please remember that executing the “Advanced
Format” deletes all the songs recorded on the internal HD.
The disk on the MR16 is not designed for long term storage. Once you have done a recording session, mixed your recording and created the stereo WAV file in the 2MIX folder then download it to your PC or burn it to a CD THEN re-format the disk for the next recording session. Use your PC or a CD for long term storage.
