Am i correct in thinking that this drive may be failing based on this output?

4-22-2006 12:08:31 pm: NWPA-3.20-0
NWPA-004: The CDM driver deactivated device [V281-A1-D3:0] WDC

Device "[V281-A1-D3:0] WDC WD2500JD-22HBB0 f/w:08.02D08" deactivated by
driver due to device failure.

I can duplicate this error by getting the properties of this drive as it
calculates space, when it hits block 45809023, nw6.5 sp3 successfully
dismounts the volume with the above warning message.

Thanks
