How to recover deleted data - Korg D3200 Digital Studio

Unless you backed up your data as described on page 123 of the manual, you may be out of luck. http://www.fullcompass.com/common/files/12278-D3200_E1_633661369446200000.pdf

You have a memory problem. If you are using a flash card for memory or a CD drive or perhaps you have configured an external drive, you need to free up some space. Try deleting tracks or songs you don't need anymore.

Each song is independent on a CompactFlash
without affecting other songs. You can give a desired song name for managing recorded songs
(see pages 23 and 91).
Recorded track data is stored in a song as mono WAV files.
The MR-8mkII can convert the two WAV files recorded on tracks 7 and 8 (L and R) to a stereo
WAV file (see page 115).
You can export the converted stereo WAV file to your USB-connected personal computer, and
use the file by a music software application or make an original audio CD on the computer using
a CD burn software application. You can also burn an audio CD by using an external CD-R/RW
drive connected via the [USB HOST] port of the MR-8mkII (see page 115 and 123)

I am not sure about specifics for your model but if you use the internal memory I understood the data was kept if it either had batteries fitted or the keyboard was left plugged into the mains ( even if the keyboard is turned off )

I guess with hindsight it would have been wise to save the data to a USB backup before turning off.

With IDES4, I can load factory defaults to my WK8000.
WK500 uses DATA MANAGER 5.0. If I am not mistaken, you can only save/restore/delete "user data" from and to the instrument.
FACTORY Settings are always unchanged in the instrument and it reset itself every time you power cycle.

Make sure you do NOT have ANY antivirus/antispam/antiadware OR network links active. These high priority programs will steal the processor to do their scheduled tasks and your audio will get overrun. All such programs need to be removed or killed while running audio programs. Another problem can be caused if your disk is getting errors and it has to do retries to recover the data.

You need an application to recover your deleted files.

Some of these data recovery applications are free and does not cost you a dime.

Others you will have to purchase.

Here is a YouTube video that show you how to recover your deleted files.

Good luck

 The initialisation function erases all backup data in the instrument's flash memory and restores the initial default settings. To clear data backed up to the internal flash memory-panel user setting, registrationmemory-turn the power on by pressing the standby/on switch whileholding the highest white key on the keyboard. The backed up data will be erasedand the default values restored.Initialization does not delete the files transferred from the computer.

This is a common problem if proper closure cannot be done is is not done by mistake.

You MIGHT try asking this on the VSplanet.com site where they discuss these recorders.

You may have to reformat your unit and of course lose the data.

Try pages 14 and 15 also 23 also44 also page 66 also 83 also 90(purge samples) 103 (memory cards) 11 formatting page 108 deleting data in memory before loading, I'd suggest page 112 (save the contents by backing up to computer) then wiping the memory card. I don't have one of these units and I see the hard drive is an option which I don't know if you have. Read the manual from beginning top end and always save your work before deleting anything. Hope this helps.
