Have two laptops, off internet for a week, both Dell's XP-SP3 patched current, running SAV 9. Both have similar symptoms. Before boot error, get warning of low drive space (> 1GB available on one, >60GB on other) Will boot Safe Mode, Tried Chkdsk, no Joy. Did a ghost to preserve before flatten, got message about incorrect file size report on temp internet - remove the ie5. folder restarted ok, until next boot. Safe mode V_scan doesn't find anything and V-def's are 11-06 and 11-07 on the two beasties.
