Note I removed other storage group folder and problem still persists ie its not storage 
pools causing problem.

I see a few of these after the above event:

2008-09-21 10:53:41.031 TVRec(3): ASK_RECORDING 3 0 0 0
2008-09-21 10:53:41.190 TVRec(3): Changing from None to RecordingOnly
2008-09-21 10:53:41.196 TVRec(3): HW Tuner: 3->3
2008-09-21 10:53:41.262 AutoExpire: CalcParams(): Max required Free Space: 3.0 GB w/freq: 
8 min
2008-09-21 10:53:41.270 scheduler: Started recording: Afl Game Day: channel 1006 on cardid 
3, sourceid 1
2008-09-21 10:53:41.871 TVRec(4): ASK_RECORDING 4 0 0 0


not sure what that means...
