Error With Chkdsk

[RedneckTech]

So I'm working on a general maintenance script. Part of it is to run chkdsk (just check no /f /r) and report that to a file. So far whenever i run the script, everything works perfectly, but i get errors on the chkdsk readout file, but then if i follow up with running chkdsk manually i get no errors. even piping results to a file.

so far has happened on a Dell XPS and Dell Precision both using the original factory image (Win 7), and a Dell Vostro 200 (Win XP)that has been reformatted like a week ago.

The error is always with the volume bitmap.

Here's the script im running:

If ProcessExists ("chkdsk.exe") <> 0 Then
   $pretime = TimerInit()
   While ProcessExists("chkdsk.exe") <> 0
      Sleep(1000)
      If TimerDiff($pretime) >= 1800000 Then
         FileWriteLine ( $DiskSick, _NowCalc() & "  Checkdisk was already running. Appears to be hung")
         $Defrag = 0
         ExitLoop
      EndIf
   WEnd
Else
   FileDelete (@WorkingDir & "Checklog.txt")
   Sleep(1000)
   $checklog = @WorkingDir & "Checklog.txt"
   $qchecklog = Chr(34) & $checklog & Chr(34)
   Run (@ComSpec & " /c chkdsk >> " & $qchecklog)
   $runinit = TimerInit()
   While ProcessExists("chkdsk.exe") <> 0
      Sleep(1000)
      If TimerDiff($runinit) >= 1800000 Then
         FileWriteLine ($DiskSick, _NowCalc() & "  Checkdisk appears to have hung")
         $Defrag = 0
         ExitLoop
      EndIf
   WEnd
   While ProcessExists("cmd.exe") <> 0
      Sleep(1000)
      If TimerDiff($runinit) >= 1800000 Then
         FileWriteLine ($DiskSick, _NowCalc() & "  Checkdisk appears to have hung")
         $Defrag = 0
         ExitLoop
      EndIf
   WEnd
EndIf

edit. Fixed the autoIT to show loops correctly

have looked it over and cant seem to see anything causing the issue. have even gone so far as to "Run": cmd /c chkdsk >> C:Users__DesktopChecklog.txt

it still comes up no errors, but then follow with script and get errors. it has to be something with the way that the script is running checkdisk. if this particular error is nothing to be worried about i can just write some lines in to ignore it if it's the only error. Would still like to know why just for my own knowledge though

[BrewManNH]

Are you running this on your C: drive? Doesn't your log tell you that there will/might be errors reported even when there aren't any errors?

The volume is in use by another process. Chkdsk

might report errors when no corruption is present.

[RedneckTech]

right. i understand that. yes it's on the c drive. Which is why i have 2 questions.

1) is this caused by the way AutoIT is written? (only happens when i run the command from an autoit exe or script) and if so (just for curiosity) what is it that causes this?

2) is this particular error something that can be a severe problem or is it ok to write into the script that this error is ok?
