Hi,
I recently upgraded my rio Mark 2 by adding a WD 120GB HDD. It's been working fine but locked up mid song today. A power off and on hasn't cured it.
player software is: Linux version 2.2.17-rmk5-np17-empeg55-hijack-v508 (hijack@rtr.ca) (gcc version
2.95.3 20010315 (release)) #2 Fri Jan 9 16:06:35 EST 2009

I noticed this error in hyperterm.
Mounting first music partition
Tried to mount /dev/hda4 as reiserfs but got error 19
and also this
show_message("Zeroing hda3")
/bin/cat: write error: No space left on device
Done!

Full hyperterm results are attached
