Thank you both for your help. I connected the player via usb, deleted all music files from the internal drive , scanned and repaired the internal drive (no errors) I inserted two new sd cards and put one flac file on each of the internal, sd1 and sd2 cards. I reset the device to factory settings and rebooted. On power up I did a full rescan. The library then showed one file on sd1 and one file on sd2. The internal drive did not show in the folders directory and the file i put on it did not show in the library. Remounting on the usb/computer showed the file still on the internal drive. The internal drive shows as 12.4GB I assume the other 3.6GB is allocated to the system.(wish I could see that !) I still wonder if I'm missing a file on the internal drive. I can't think how to force the system to show/scan that drive for certain. Any more ideas would be much appreciated.
