Hi Albert! Let's try this:
Please let me know if you have any luck with the above.
The Home folders are created by the device -- not by OS X -- so this appears to be a problem with the Walkman itself. I'm not as intimately familiar with that particular device as I feel I need to be in order to further assist, so I am going to open this question up for some of our other Experts to chime in on.
Please bear with us...we'll have someone with you shortly!
Hi Albert, I'm Carl and I will be assisting you where eeewing left off. I have seen this issue before in my repair store and we tried everything! Even formatting the internal memory in the settings does not resolve this which is only performed in extreme situations. I just took a quick look online and it's a well known issue and Sony has no resolution for the problem at this time. Here's a forum full of consumers with the exact same issue as you: http://www.anythingbutipod.com/forum/showthread.php?t=36035.
If you need any clarification or additional help, please feel free to ask me.
I am available if you need any further assistance with this.
