Hi cereal_killer
Thank you very much for your kind responce.
First, I have to apologize for lack of information.
I'm using a windows 7 host PC so the iPod has a FAT32 partition.
I tried the test build but the result was the same.

But I noticed that SSD has problems with RB when I read the forum posts for the first time.
So I re-installed the original 30GB HD to my iPod then I could easily use RB!

Thank you all for being able to play 24/96 WAV files from vinyls.
My iPod became a HiFi audio machine. I love RB.

So I'm planning to make an adequate file system on my 64GB SSD with Linux or purchase a 240GB HD to increase capacity to copy all my WAV files.
Thank you again for giving me a chance to increase the capability of my iPod.
I appreciate all the effort to make up such an excellent environment of RB.
