This have been a long awaited feature by the BDD\MDT Users

How can i do, using BDD\MDT Tools,  a repartition of the hard drive while doing a ZTI Refresh

Or.

Hi Or!

I solved this problem and for us it works fine.
First I wrote a litte vbscript called ZTIRepartition.vbs and copied this to \\server\distribution$\Scripts.
Update deployment points and add a Task Sequence on first position which runs a command line:

cscript.exe "%SCRIPTROOT%\ZTIRepartition.vbs" with the option "Task Sequence Variable DeploymentType equals REFRESH"

Update your OS Package Files on SMS (after you add the file in the program), update DP and run the osd advertisement. That´s all.

Script ZTIRepartition:

########################################

Dim WshShell
Dim objfs

Set WshShell = WScript.CreateObject("WScript.Shell")
Set objfs = CreateObject("Scripting.FileSystemObject")
Set objshell = CreateObject("WScript.Shell")

strComputer = "."

Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colDiskDrives = objWMIService.ExecQuery ("Select * from Win32_DiskDrive")

For each objDiskDrive in colDiskDrives
    strPartitions = objDiskDrive.Partitions
Next

strCount = strPartitions

If strPartitions = 1 Then
    WScript.Quit
Else

    Set objAusgabe = objfs.CreateTextFile("C:\Temp\Repartition.txt")

    objAusgabe.WriteLine "select disk 0"

    For X = strPartitions To 2 Step -1

        objAusgabe.WriteLine ""
        objAusgabe.WriteLine "select partition " & strCount
        objAusgabe.WriteLine "delete partition noerr"
        strCount = strCount - 1

    Next

    objAusgabe.WriteLine ""
    objAusgabe.WriteLine "exit"

    cmd = "diskpart.exe /S C:\Temp\Repartition.txt"
    objshell.Run cmd,0,True

End If

The fact that in the sysprep.inf the varible ExtendOEMPartition in the section
[Unattended] is set to 1 makes minisetup use the whole disk.

To repart the disk starting from RIS I use the Winbom.ini in WinPE:

[DiskConfig]
Disk1 = Disk1.Config

[Disk1.Config]
WipeDisk = Yes

Size1 = *
PartitionType1 = Primary
FileSystem1 = NTFS
QuickFormat1 = Yes
SetActive1 = Yes

For more partitions:

[DiskConfig]
Disk1 = Disk1.Config

[Disk1.Config]
WipeDisk = Yes

Size1 = 25000
PartitionType1 = Primary
FileSystem1 = NTFS
QuickFormat1 = Yes
SetActive1 = Yes

Size2 = *
PartitionType2 = Primary
FileSystem2 = NTFS
QuickFormat2 = Yes

Hope this helps a little bit! Dietmar
