Hi,

I need a simple vbs to format and set the drive label of a usb. I found this but it does not seem to do anything on Win8. Any suggestions please?
Tom

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colVolumes = objWMIService.ExecQuery _
("Select * from Win32_Volume Where Name = 'E:\\'")

For Each objVolume in colVolumes
errResult = objVolume.Format("NTFS", true)
objVolume.Label = "MyLabel"
Next

Open in new window

Try removing the double "\"...with this adjustment:

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colVolumes = objWMIService.ExecQuery _
("Select * from Win32_Volume Where DriveType=3)

For Each objVolume in colVolumes
  If objVolume.Name = "E:\" Then  'Filters for ONLY drive E:
    errResult = objVolume.Format("NTFS", true)
    objVolume.Label = "MyLabel"
  End If
Next

But from an elevated environment?
For instance, launching your app using
cscript FormatUSB.vbs

Open in new window

in a command prompt...does the command window state that it's an Administrative environment?

Since the suggested change i get an 'unterminated string constant' error on line 6

and the same if run as cscript... from a cmd window

the command window does not specifically stat admin environment. I can however run lots of other scripts without a problem if that helps?!

i went back to my original script and ran that from an admin cmd and it ran and formatted the drive ok but did not rename its label

Will it be possible to make this work from a non admin point of view though?

Don't know of a way to do it without elevation.  You could create a shortcut and mark that to only run as admin, but you'll get that pop up asking you to confirm it each time.

Here, try this adjustment with the elevated cmd:
strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colVolumes = objWMIService.ExecQuery _
("Select * from Win32_Volume Where Name = 'E:\\'")

For Each objVolume in colVolumes
  errResult = objVolume.Format("NTFS", true,,"My Label")
Next

This works fine if 'elevated'. The other option is i can compile it using exescript then right click and run as admin.

Thanks for your help
