    defragmentation and a small problem

    Hi,

    congratulations for this software! It works really great on my Amilo Notebook (Centrino Pentium M).

    I have two questions:

    First: can I do a normal defragmentation with windows? Will this affect the Ubuntu/Wubi installation in any way?

    Second: when I boot Ubuntu the normal Ubuntu load screen appears. Then it removes and I see a black screen with many status messages. Most of them returns an Ok but one shows a red Fail message. I am not able to read which operations fails I think its something with the virtual discs and "file not found". The screen disappears very quick and Ubuntu starts. Is there any possibility to see a log file or pause the boot sequence so I can read what fails?

    Thank you very much and please forgive my bad englisch.
    Bastian

    EDIT I use the test 3 release and mit Host OS ist Windows XP Media Center Edition (so it is XP Pro)

    As far as I know, defragmentation in Windows should not affect Wubi, but I have not tried it yet...

    As for the "file not found" error, this is might be a problem with mounting the extra.virtual.disk swap partition. It is not a critical problem, but it might reduce Wubi's performance, since it will not be able to use virtual RAM (on your hard drive), only physical RAM. See this post for more info: http://ubuntuforums.org/showthread.p...ual.disk.extra

    Log files are stored in /var/log

    In any case, please report your findings here on the forum. Thanks.

    extra.virtual.disk does not affect performance and you can safely ignore the error. It is an extra disk to expand disk capacity later on if needed. So at boot we look for it and if there is none an error is raised.

    Re: defragmentation and a small problem

    running xp when I try to defragment my disk, i get one file

    21 5.86 GB \wubi\disks\home.virtual.disk

    which won't defragment. it's big enough so that in theory I should defrag every time. Can I erase it or what ?

    Will it be automatically recreated ?

    I believe that this is the Wubi intstall itself - you don't want to delete that!

    What program are you using to Defrag? DiskKeeper and the Windows Defrag program aren't very good, I recommend PerfectDisk, it's awesome.

    21 fragments for such a file is not problematic at all. That makes an average size of 250 Mb per fragment. It won't hurt the performance in any way.

    If only someone would port Reiser4 to Windows - no more defrag

    You could also use JkDefrag. It works like a charm ^_^
