[QUOTE="dir, post: 509105, member: 24485"] Whenever I resume my Vista htpc pc from a suspended state, the hard drive goes crazy (ie. it's solid on) for about 5 to 10 minutes or longer. I've checked Task Manager and Process Explorer, but there's no processes using any CPU to speak of. The only process that seems to be active, and JUST BARELY, is my anti-virus software. But it's not doing anything; it's not doing an active scan, it's not doing any file IO. I've only seen this on my Vista PCs. I have two Vista PCs; they are entirely dissimilar in every way (one uses RAID; the other has a single hard drive. One is an Intel CPU, the other AMD. The motherboards are 4 years apart in age.). The htpc PC has 2GB of memory. Within Task manager, I have enabled I/O Read Bytes and I/O Write Bytes to see what processes are doing I/O. None are doing anything substantial. The total CPU usage is 0% to perhaps 2% occasionally during this 10 minutes (and most of that is Task Manager updating it's display!). The motherboard BIOS are the most current and now quite old and stable. There is no RAID ability on this htpc PC. Here's some more things I've checked: - there are no network applications accessing the PC; no remote backups, etc. - there are no events in the event log. The file system is fine (chkdsk etc. report no problems). - the hard drive passes all tests (i.e. no hard drive issues) - the following services are [B]not [/B]running: Offline Files ReadyBoost SuperFetch (I've tried it with Superfetch enabled but it makes no difference) Volume Shadow Copy Windows Search (i.e. Windows Indexing). This happens every time the PC is resumed. It's really frustrating because there's no way to see what process is doing this. It's almost like Vista has some hidden processes that don't appear on the Services / Processes lists that do some sort of major indexing/checking/rehashing/recovery after every resume. Another theory I have is that upon Resume, MediaPortal's TV Server starts recording a TV show, or peforming a Comskip analysis on my recordings, or is creating thumbnails of photos or TV shows. But again, no CPU or I/O activity is recorded against any processes and MediaPortal isn't even running. And it happens even when there's no scheduled recording to be done or overdue. It happens when I suspend manually or it does it automatically. MediaPortal may have been running at time of suspend, or (usually) isn't. Any ideas? [/QUOTE]
