I'm getting the same error. I was trying to do a favor for a friend. So I've download the firmware and followed step by step and when update was in 99% gave me such error. Now I can't try to update again. The MP3 shows on My Computer but when I try to open say that has no disc. The firmware also says there's is no disc and can't update. I can't believe I will lose this MP3 just trying to do a favor and I can't get support from Sony since Sony doesn't has a support for the MP3 on Brazil at all. So it's over or there's a hope yet? Any help I'll be greatful.
