I have a pa500 with the exact problem, and exact messages.
did anyone find a solution?

where would I find the sd ram in the unit to replace it?

thanks

dont believe your board should be replaced in case of loading inconsistent datas.

if that would happen, everybody would be to angry to load sounds, styles or performances.

it is enough to reformat corrupted NAND-memory, to install the newest OS and to load resources and your keyboard will work again.

as there is no reformatting-software like for pa800, reformattin NAND is to do with servicemenue as described in service-manuals. this information you get from Korg. so did i and i am not angry to load sounds, styles, performances ...

cheers

Hallo Alfredo,
It is right, that formatting don´t recover bad sectors.

Maybe I have problems with english language, but on my opinion both members were loading incompatible datas. And they used a procedure “SSD-formatter” that would take them to “SSD format page” and than they found the instruction “there is no OS” etc. And they used combinations of buttons during power-on that does not check the NAND, but did something other I don’t know. But they did not perform a NAND-formatting!

Check and format NAND are simple serviceprocedures, to be necessary to do after you have loaded bad data. Usually keyboard get freezing or you get message like “device generic error” if you try to load some i3-styles or 128 sounds to usersound-bank 16, whereas capacity is only 64 to load etc.

Checking and formatting NAND will show the message “zero bad sectors”, and then it is possible to load OS from SD-card as described in manual.

Believe charly67 as he wrote he was loading user sounds bank when trouble occurred, keyboard frozed and was unusable and made the reset information that he got from Korg to fixed the problem.

But if there would be bad sectors, why not to check them with serviceprocedure to see if the NAND is in “good condition” and to get the information about amount of bad sectors, before you change a board?

It can not be necessary to change a board, after you loaded bad data. If that would happen, i had to change my board 5 times last six months. Make that simple reset with serviceprocedures as there is no reset-button on Pa500. And I can not understand why this resetting-procedure is so secret, because you get this information from Korg.

About the NAND flash "zero bad sectors" message this is a really good news because user are able to check memory integrity before loading OS resources.
Also is important to use the right OS resources file, so any user should check the NAND integrity with the "format" procedure.

Also in the case of bad sectors I think the system should return a "checksum error" or "error writing OS resources" message in case of bad sector on the NAND flash.

Thanks siebenhirter for your recommendations.

The information about a reset for the pa500 is still available on Youtube. Search for “korg pa500 pictures” posted by seaboss67, and on Dailymotion, search for “korg pa500 pictures” posted by bingo73.

Hi,

Since it seems this problem can happen more often than expected, we put the Pa500 Factory Reset in our web site. You can use this file to format the internal memory of all Pa500 exemplars (International or Local versions).

Please only use it in the event of the instrument not starting, due to damaged data in the internal memory.

The Reset file can be found here:

Best regards,

Thanks to you Paolo and all the Korg Team in Italy! I feel much better having this tool available should I ever need it.
