100% disk activity, but very little disk transfer
I've often noticed that sometimes my boot hard disk goes crazy, disk
activity light flickers constantly, system becomes unresponsive, but there's no particular process hogging the processor cores. I managed to watch one such incident while Hard Disk Sentinel was present in memory, and when I looked at the boot disk in the Performance tab, it showed 100% activity, but data transfer was down near zero. Obviously, I had to reboot the computer to get it back to normal. I'm talking about Windows 7 Ultimate 64-bit in this case, but I've seen similar things happen under Windows XP Pro 32-bit in the past too. Another thing I noticed is that during this time, the System's own SVCHOST.EXE program is using up a lot of memory too, over 300MB by itself! What could be happening here? Yousuf Khan |

Are you saying that it doesnt when that isnt happening with the drive ? What could be happening here? |

If svchost.exe is not running out of the windows.system32 folder, then it could be malware that it is running. You should check what svchost.exe is hosting by using Process Explorer. PE is free to use, and you can use Bing or Google to find out how to use PE to look at a running process, see what it is hosting and see what directory a process/program is located when it is running. -- posted with a Droid |

Yousuf Khan That used to happen a lot on systems with insufficient memory, swapping program segments in and out from the page file. I guess it could also happen where the page file was either not used or too small an allocation. Ed |

But I have 8GB of memory on a 64-bit system, and taskman was showing that I was only using about 4.9GB out of the 8GB. That's still quite a lot being used up, but still not saturated. During normal operations, the memory being used up ranges between 2.5 to 3.0GB. Yousuf Khan |

It only host processes. -- posted with a Droid |

Likely it is that, but since svchost.exe is used for hosting a lot of stuff, its not necessarily bad. Have a look at svchost.exe with google and you will find its quite complex what it can be used for. |
