Once I had a problem with a file on my AUDYA 76 HardDisk. On top of the index of the HD here was a file named with some chineese characters or something like this. I could not delete this file with my AUAYA and I could not delete it with Windows 7. Then I found "LINUX MINT 14.1 Mate" on the internet - downloaded it - burned a CD with this program - started my PC from the disk - connected my AUDYA with USB. And now I could delete this silly file without problems.
Maybe you could use this to recognize the SD1 drive??? I donīt know.
Thank you.
