Dont know if this will help but there s an HD5 firmware update that can be found here;
http://www.sonydigital-link.com/DNA/common/asp/details.asp?l=en&v=&m=frm
It says 'Important note:: A certain number of NW-HD5 Network WALKMAN units may rarely stop responding on startup under certain conditions. In order to resolve this issue, we have provided a firmware update to version 1.2 for the Hard Disk Network WALKMAN NW-HD5.'
Best of luck, D
