    Can I stop disk check at startup if I use smartctl?

    There is a default hard disk check program with the ubuntu12.04 which runs automatically at the time of logging in, may be after a gap of every 30 or 40 sessions. However there is also a program: "smartctl" which can do the job very efficiently. If I choose to use the later to check condition of hard disk, is there any harm if I stop the default hard disk condition checker? How do I do it? I am especially worried about frequent power fluctuations at our ocality in recent times. Though the power to my desktop is through an offline UPS, I am afraid frequent power level fluctuations may soon damage the hard disk. So it is best if I get some forecast regarding that. If you know of any better program for that specific purpose, please mention it. Thanks.

    HI:

    This looks like a good application. Here is more information on it to help you know more about it-

    http://smartmontools.sourceforge.net...martctl.8.html

    From what I read if you skip the disk check it will do it again at the next re-start-

    There is also another application for monitoring if you'd like to consider it-
    It's called CPU Frequency Monitoring

    I installed in on a distro called "Voyager" which was built on Ubuntu 12.04- You can find it here:
    https://launchpad.net/ubuntu/+source/cpufrequtils

    is there any harm if I stop the default hard disk condition checker
    That; I don't know so be careful until another member here advises you--

    You can also use the sensors command to see if your system is running hot-
    Code:
    sensors -f | grep -i temp
    -f is for fahrenheit, -c is for config file, -h is for help, -s is for set root only, -u is for raw output for degug and -v is for program version.

    Hope that helps-

    fsck and smartctl are two different things, there's no "one replacing the other." fsck is (literally) file system check, which works with a bunch of different possible file systems; ext2, ext3, ext4, etc.

    smartctl is a check of a disk drive's SMART data which lies "underneath" any file systems in use on the disk's partitions.

    Users should know that fsck has been disabled in the past few releases and should be enabled by the user.

    See :

    http://ubuntuforums.org/showthread.php?t=2141727

    How to check if it's disabled, and how to enable fsck is explained in Post #3 of that thread.

    As oldos2er points out, condition of the disk drive and condition of file system are two different things.
