Failed to run task sequence with following error 0x80070570

In this case, during operating system deployment using SCCM 2012 r2 task sequence, I have experienced error 0x80070570 on some machines:

From the MSDN, descriptive information for the error (0x570) 1392 is: "The file or directory is corrupt and unreadable."

This task sequence job was to deploy new operating system using wipe and load scenario. In order to fix this issue and allow the task sequence to finish it's job, I've entered into debug mode using F8 and used diskpart. Since, the operating system deployment scenario was wipe and load, I didn't care much about the data stored on disk. So, here is the syntax for disk cleaning:
diskpart -> list disk -> select disk 0 -> clean -> exit
After cleaning the disk, the task sequence has successfully installed the required operating system.

Finding scripts in GPOs

For this case I wrote a simple PowerShell easy to read script for finding GPOs with scripts and their links to OUs. The script requires domain administrator credential for enumerating GPOs machine startup folder. For populating $dc and $dom variables the script requires online domain controller and domain name. Then the script will start to enumerate policies folders searching for files with vbs,bat, and vbe extensions. It will also filter out with regex the gpo guid found between the curly brackets "{}"in the full file path. Using the gpo guid the script will resolve the gpo name and OUs where that gpo is linked. At the end the script will output the data.

$dc = Read-Host "Online DC (example:dc1)"
$dom = Read-Host "Domain name ("

dir \\$dc\SYSVOL\$dom\Policies -Include *.vbs,*.bat,*.vbe -Recurse | select -ExpandProperty Fullname | Select-String -Pattern "(?<=\{).*?(?=\})"  | % {

    $gpo=get-gpo -guid $id
    $ou =Get-ADOrganizationalUnit -LDAPFilter "(gPLink=*$id*)"

    Write-host $_
    Write-Host "GPOName=" -ForegroundColor Red -NoNewline
    Write-host $gpo.DisplayName -NoNewline
    Write-Host "`tStatus=" -ForegroundColor Yellow -NoNewline
    Write-host $gpo.GpoStatus
    Write-Host "OUlinks=" -ForegroundColor Green -NoNewline
    Write-host $ou.Name
    Write-Host " "


Feel free to customize or modify the script to satisfy your needs.
