Unreliable Cronjobs - fREW Schmidt's Foolish Manifesto
The general pattern that we suggest at work is to run your cronjobs five to ten times more often than you need to and to exit early if there is no work to do. In addition, you should monitor what the cronjob produces (which obviously varies wildly, per cronjob) rather than the sythentic exit code or output from the cronjob. This can both help you to avoid being paged when a cronjob is a little flaky and additionally detect a cronjob that is failing but still exiting zero.

<code class="language-bash">$ top -d 1 -b |grep <process> >>somefile</code>

Where are checkdisk/scandisk logs ? - Windows 7 Help Forums
if I remember try..

Go to Start > Run and type: eventvwr.msc /s , and hit enter.
When Event Viewer opens, click on "Application", then scroll
down to "Winlogon" and double-click on it. This is the log
created after running Checkdisk.

In Event viewer, under Application logs, you need to double click on "wininit".

"Winlogon" is applicable for XP.
