1) My pa800 showed "SSD Media Error Press Media to confirm Format".
2) I had pressed Media .
3) it showed Nand Formatted USB Enabled.
4) I Formatted my Pa using Pa800_Format.pkg
5) Then loaded Pa800_os_res_v203.pkg
6) Then loaded my own Set

Every thing seems to work Correctly.

If i swich off the keybord then turn it on in less than one hour , it still no problem ...
But by trying to use it tomorrow for exemple the Pa800 showed "SSD Media Error Press Media to confirm Format" again !!

i repeated this process about 3 or 4 times ( by obligation )

it's not a solution at all ... and I'm afraid doing that could damage my keyboard


really need ur help

I would get it serviced by Korg.

Try to replace board button size st-by lithium battery ! Bios state seems to reset after some hours , which means
that no voltage source provides energy to maintain some significant bios data.
But since many years have passed and my memory do not help me , if no battery exist there then Pa800 must be serviced !

Hi Slim101010,

Kindly let us know if you have found any solution.

Thanks

The defective CPU board. A good technician can fix, not necessarily areas should be replaced.

Hi

Ensure that your PA800 serial number is greater than 69XXXX if it is below that ver 203 will not work. You will have to back to Ver 201 /2 .

Best of luck
