blasto Posted February 9, 2006 Share Posted February 9, 2006 Hi,you can find the sysinternals filemon output below; this hdd event occurs every minute with high disk activity. its recorded while there were no other programs running, indexing, shadow copy and system restore sevices were disabled. I have checked another computer with sp2 and this acitivity wasn't that often. this is happening on a clean fresh setup not connected to internet and virus free. what may cause explorer to do such heavy activity regardless of system being busy or idle. I'll appreciate any ideas, thanks17:16:07 explorer.exe:1840 IRP_MJ_CREATE C:\ SUCCESS Options: Open Directory Access: All 17:16:07 explorer.exe:1840 IRP_MJ_QUERY_VOLUME_INFORMATION C:\ SUCCESS FileFsFullSizeInformation 17:16:07 explorer.exe:1840 IRP_MJ_CLEANUP C:\ SUCCESS 17:16:07 explorer.exe:1840 IRP_MJ_CLOSE C:\ SUCCESS 17:16:07 explorer.exe:1840 IRP_MJ_CREATE D:\ SUCCESS Options: Open Directory Access: All 17:16:07 explorer.exe:1840 IRP_MJ_QUERY_VOLUME_INFORMATION D:\ SUCCESS FileFsFullSizeInformation 17:16:07 explorer.exe:1840 IRP_MJ_CLEANUP D:\ SUCCESS 17:16:07 explorer.exe:1840 IRP_MJ_CLOSE D:\ SUCCESS Link to comment Share on other sites More sharing options...
cluberti Posted February 9, 2006 Share Posted February 9, 2006 Do you have antivirus software or antispyware software involved, or even backup software? Any piece of software that uses a filter driver is suspect. Link to comment Share on other sites More sharing options...
blasto Posted February 9, 2006 Author Share Posted February 9, 2006 I'm using Avg antivirus free ed. but as I said I'm ending all non-system processes before testing, anyway the explorer keeps up spinning the hdd. Filemon doesn't show any application other than explorer, how can I track such an embedded driver or else? Link to comment Share on other sites More sharing options...
cluberti Posted February 9, 2006 Share Posted February 9, 2006 Process explorer can show you what's actually running in the explorer.exe process. Link to comment Share on other sites More sharing options...
