I've been very pleased with my new HD5 over the last two weeks in all respects except for one major annoyance. On 7 or 8 occasions (yep, roughly every other day) since I started using it, it has frozen - it has stopped playback suddenly and all buttons have ceased to work. In the majority of cases the screen has remained on and the only way to reset it has been to open the battery compartment. On two occasions however the HD5 has manged to reset itself displaying the message 'System Error 020'. I have emailed Sony and just received a response advising me that "I am sorry to read of your difficulties with your new NW-HD5. As it was recently purchased I would suggest that you consider returning it to your original supplying retailer (albeit Sony Style) and request an exchange or refund as appropriate. I am sorry that we are unable to assist directly on this occasion blah blah" Not a great deal of help. So, has anybody else experienced this problem, is it a 'feature' of the HD5, is it possibly something I'm doing wrong or do I just have a faulty unit? I will probably initialise and re-transfer my tracks and then return the thing for an exchange (probably, I love this little baby) if that doesn't work but would like to know if anyone else has experienced this/has any thoughts before I do so. Cheers, Hrochnick.
