Thanks for your response….
The NSLU2 is running V2.3R63-uNSLUng-6.8-beta, from a 300Gb Maxtor drive attached to USB port 2. It is the only drive attached.
The files (MP3 and FLAC) are all located in the MP3 folder visible through the web administration interface of the NSLU2, which also happens to be the /public/mp3 folder.
Where do I find the log file?
Is there any other info I can provide that would be helpful?
