    Default system restore

    In the past month my root folder has become corrupted 3 times. General system restore doesn't help and installing the default kernel doesn't help. I don't expect a forum to be able to help with the corruption issus but is there any way to restore root without a complete re-install? It's a little time consuming.

    Describe "corrupted".

    What is that "system restore"? First time I see that mentioned.

    What openSUSE version do you have?

    If you really want to know, corrupted meant the mbr is trashed and the sound drivers are missing - even to insmod. Look for System Restoration in Yast. I use 11.3.

    Grub might be fixable but I don't know how. This time I put it in the root folder instead of mbr. I THINK drivers are in the kernel which should mean it's corrupted.

    The grub error message is 'unknown file system, cannot mount partition'.

    what could be trashing the mbr?
    are you dual booting to another system?

    during the past month (when this has happened three times) did the
    machine take in kernel updates or other changes requiring a
    reboot...and, were any of those required reboots done by a system other
    than openSUSE? (if so, the mrb was not 'trashed' but only reset to allow
    the other system to complete its update process--which _included_ a
    reboot)..

    or (since you have given zero insight into your hardware) how is the
    health of your disk? maybe it is failing--i sure can see no connection
    between the mbr corruption and loosing a sound driver..

    are you experiencing system lockups, of unexpected system crashes, or
    maybe pulling the plug, or anything else which might leave the disk in
    an unclean and/or jumbled state?

    to directly answer you question (with FAR too little info given to
    actually help):

    Q1. is there any way to restore root without a complete
    re-install?

    A: sure, restore from a system backup taken when all is well....but,
    note, a restore process which depends on being able to boot will not
    succeed if unable to boot because the mbr is trash....so, boot from a
    live CD (or whatever) and run the restore from an external/optical disk,
    or partition on the disk which is not within the area needing a restore


    > Look for System Restoration in Yast. I use 11.3.


    never use it myself...but no, it won't be useful if the disk is so
    trashed you can't boot...it seems to me if you are having sound drivers
    mysteriously disappear you might also expect any saved restore image to
    be corrupted also...so, you really must find a more dependable place to
    restore from..

    of course, the best path is to discover and repair the root cause of the
    corruption..

    oh i forgot to say (with reference to above): of course he really wanted
    to know, your initial post was so devoid of info as to make giving help
    totally impossible..

    which is exactly why i didn't try to even guess an answer until i knew
    more..

    because all helpers here are *unpaid* volunteers i'd suggest you adjust
    your attitude and read here if you have more questions:

    With a complex problem that may or may not involve hardware; that isn't easily replicable; that I probably don't understand very well, I don't expect a solution. What I would like is what I asked for: a faster way to restore. Two hours is too long.

    as said, restore from backup (which should be much faster than a
    reinstall)..
