First I used a 8MB SIMM and had around 3GB MP3 on the disc in a lot of
directories and every thing was fine.
Now I added 20 albums by deleting the whole disc and write back the new
package of now 4.6GB. And I changed the SIMM to 16MB to be able playing
longer songs.
Now I realize that the most of the old albums are played correctly. But
the last few albums of the old package and the new albums showing the
following effect:
When a song was played it dosn't load the next one from the disc. A
part of the next song seems to be already in the SIMM and it plays it
until the end of memory is reached. Then the rest of the song is
loaded. The load from disc is now somewhere in a song depending on the
length. When I switch off my player in such a position and switch it on
again the last title played starts somewhere in the middle of the song.

What did I wrong???
