Demigrator.exe / DriveExtenderService slowing down WHS? RRS feed

  • Question

  • Right, since I am having not much success in my thread here : http://social.microsoft.com/Forums/en/whssoftware/thread/109fccf8-5c1a-4c16-b0d2-eb45246784d9

    I decide to ask a more specific question, hoping someone would help. I am pretty sure that the issue now is caused by the said servce. If I enable it everything will take ages to load. CPU usage surprisingly is low but I virtually can't do anything at all. Everything takes a few minutes to register. This is really getting very annoying.

     

    I am wondering if anyone has the same problem? Please refer to my thread linked above for more info.

     

    Thanks.

    The fact that your chkdsk froze would seem to indicate you have a problem with one of your hard drives.

    Interesting. I ran the batch file again and this is what I've got :

    Chkdsk cannot run because the volume is in use by another

    checked the next time the system restarts? (Y/N)

     


    Seems like I have 391385988 KB in bad sectors. I wonder if this is because of some of my files which contains weird filenames. I seem to remember that my old Maxtor external HDD doesn't like that very much.

    Could this be caused by files with illegal file naming convention?

    What do I do with the bad sectors?

  • Oh, I selected N but it opened 3 more windows and does CHKDSK on all of my remaining HDDs. Nice :) Will post results later.

     

    edit: Strange, all three seems to have stopped at stage 4 out of 5.Still HDD activity though so I will leave it for now.

  • Stage 4 on a disk may take a while, particularly if you have a lot of data in your shares, and/or a lot of home computer backups.

    The bad sectors on your D: partition indicate a failing system disk. You should plan to replace the disk and go through the server reinstallation/recovery process as soon as possible.


    I'm not on the WHS team, I just post a lot. :)
