A question about Vista's built-in Disk Defragmenter

[madmatt]

Has anyone figured out how to defragment just one disk? Clicking "Defragment now" appears to perform the action on all disks.

Here's a script to just defrag only drive c in vista.
Save it as whatever.vbs

strComputer = "." 
Dim Wmi : Set Wmi = GetObject("winmgmts:\\" & strComputer & "\root\CIMV2") 
Dim Act : Set Act = CreateObject("Wscript.Shell")
Dim ObjItem,ColItems,GB, Var1
  GB = Int(1073741824)
Set ColItems = Wmi.ExecQuery("SELECT * FROM Win32_LogicalDisk",,48) 
   For Each ObjItem in ColItems 
    If ObjItem.DriveType = 3 Then 
     If InStr(ObjItem.Caption,"C") Or InStr(ObjItem.Caption,"c") Then 
      Var1 = objItem.Size - objItem.FreeSpace
      Act.Popup "Preparing To Defrag This Drive" & vbCrLf &_
      Space(3) & "Drive Letter"& vbTab & ObjItem.Caption & vbCrLf &_
      Space(3) & "Volume Name" & vbTab & objItem.VolumeName & vbCrLf &_
      Space(3) & "Total Size" & vbTab & FormatNumber(objItem.Size/GB,2) & " GB" & vbCrLf &_
      Space(3) & "Free Space" & vbTab & FormatNumber(objItem.FreeSpace/GB,2) & " GB" & vbCrLf &_
      Space(3) & "Used Space" & vbTab & FormatNumber(Var1/GB,2) & " GB", 3,"Defrag",4128
      Act.Run("Defrag.exe " & ObjItem.Caption &"\"),2,True
     End If  
    End If 
   Next
  Act.Popup "Finished The Defrag",7,"Finshed Defrag",4128

Nice one Andy, I'll take a copy of that if you don't mind 🙂

I've never been able to use the dang thing.

Keeps saying my disks don't need to be defragged 🙁

Bleh.

You know you can just click "defragment now" anyway right?

I'm not too fond of the built-in utility. I like that you can schedule it but I don't like that you can't choose which drive(s).

yeah... me too

i hope they upgrade it in sp1 (although its unlikely)

Well, in the script I posted you can edit what drive you want to defrag yourself.
Also, the defragger for Vista is pretty good under the hood.

The only reason I don't like it is the fact that you cannot choose which drive. I could care less about the drive map.

Thanks for the script, I will defiantly check it out.

I don't want to disobey the almighty kernel 😱
