lefrosth, These players are not able to support 4GB of memory 2GB is the maximum. I went back through your posts and see you listed your memory chip serial number as K9K
8G08U0M.
On Samsung chips the 4 & 5th characters represent the chip density in your case 8G which is 8gigabit or 1GigaByte.
If your player is only showing 228MB then one of the following may have happened.
The chip has been marked as a 1GB chip but is really only 256MB.
The serial number has been misread and is actually K9K
2G08U0M which is a 256MB chip.
The chip is in fact a 1GB but has failed in some way and not all the memory is accessible.
When you used the MP3 Disk Tool to rebuild the partition the slider was not set all the way to the left at zero before you repartitioned in which case you may be able to repeat the process and restore the chip to 1GB.
This is why you were having problems with file corruption because the files were being loaded to damaged sectors or space that did not really exist.
Here is a post regarding a 4GB player I purchased that was in fact a 2GB chip.
