donhorn20 Posted November 11, 2016 Share Posted November 11, 2016 (edited) How can I get the "Simple Volume Size in MB" for and Disk # I select. The value I am talking about is seen when you open Disk Management, select your disk, right-click > "New Simple Volume...". I would like to enter the desired disk number via an input box. Then return this "Simple Volume Size in MB" value. I don't want the DISKPART size as that is rounded (see picture). I already have script that extracts that, but I found out I need even more precise values. Any ideas of how to get this information? Been reading up on _WinAPI_GetDiskFreeSpaceEx() and _WinAPI_GetDriveNumber(), but I am not seeing how I could use these to get my results. One thing to note is these drives won't have drive letters associated with them at any point, so drive letter searching is useless.

Moderators JLogan3o13 Posted November 11, 2016 Moderators Share Posted November 11, 2016 (edited) Your 4095.88 is simply 4194174 / 1024. You could do that through some simple math.

RTFC Posted November 11, 2016 Share Posted November 11, 2016 If your disk is NTFS or FAT or similar, you can use my BuildPartitionTable UDF (link in my sig) to get disk/partition sizes exact to the byte.

Thanks JLogan3o13 for the reply. I do understand that simple math will get me that value. Maybe I wasn't clear enough in my original post. How can I extract the number 4194174 or 4095.88 when only providing the disk number to my interface? Scenario, a person enters the Disk number into an input field. I want to get the results of the disk 2, in this case the returned value could be 4194174 or if there is a way I can read from the disk management "Disk 2" section take the 4095.88 value, then I can do the math in the background to retain my results. Any ideas where I can find either one of these stored values, and how to extract them? Link to comment Share on other sites More sharing options...
Moderators JLogan3o13 Posted November 11, 2016 Moderators Share Posted November 11, 2016 (edited) You could pull this information from WMI (search the forum for scriptomatic if you are unfamiliar). Something like this would get the information you're after: Const $wbemFlagReturnImmediately = 0x10 Const $wbemFlagForwardOnly = 0x20 Local $oWMI, $oDrives, $sID, $sName, $iSizeinBytes $oWMI = ObjGet("winmgmts:\\.\root\cimv2") If IsObj($oWMI) Then $oDrives = $oWMI.ExecQuery("SELECT * FROM Win32_DiskDrive", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly) If IsObj($oDrives) Then For $sDrive In $oDrives If $sDrive.Index = 0 Then $sID = $sDrive.DeviceID $sName = $sDrive.Caption $iSizeinBytes = $sDrive.Size ConsoleWrite("ID: " & $sID & @CRLF & "Drive Index: " & "Drive Name: " & $sName & @CRLF & "Drive Size in Bytes: " & $iSizeinBytes & @CRLF) EndIf Next Else ConsoleWriteError("Unable to pull Disk Info" & @CRLF) EndIf Else ConsoleWriteError("Unable to connect to WMI" & @CRLF) EndIf You should be able to easily adapt this to a GUI, and change the If $sDrive.Index = 0 statement to something like If $sDrive.Index = GuiCtrlRead(<input field on your GUI>) Edited November 11, 2016 by JLogan3o13 "Profanity is the last vestige of the feeble mind.

donhorn20 Posted November 12, 2016 Author Share Posted November 12, 2016 Well I looked into Scriptomatic and tried out the code you provided. It does return the drive size in bytes, but it still is the incorrect value being captured. I even tried the Win32_Volume to see if it would produce different results. But I still get the same output. Check out what I mean. Scriptomatic returns size in Bytes = 4398040765440 I convert that to MB 4398040765440 / 1048576 = 4194298.520507813 MB Notice this isn't even close to what the Windows Properties shows for this volume. As a matter of fact you get different results depending on how you look at the volume. Ultimately I need to find a way to get 4095.88 GB or 4194174 MB based off of disk # selected. Right now I am not seeing an easy way of extracting that data. Have you guys seen this type of discrepancy before? Here is the code with a simple input box if you want to see your own results. expandcollapse popup#include <ButtonConstants.au3> #include <GUIConstants.au3> #include <GUIConstantsEx.au3> #include <MsgBoxConstants.au3> #include <WinAPIFiles.au3> #include <WindowsConstants.au3> Opt("GUICoordMode", 1) Opt("GUIOnEventMode", 1) ;0=disabled, 1=OnEvent mode enabled Opt("GUICloseOnEsc", 1) ;Send $GUI_EVENT_CLOSE message when ESC is pressed $GUI = GUICreate("", 175, 100) GUISetOnEvent($GUI_EVENT_CLOSE, "_Exit") $Label_DiskStart = GUICtrlCreateLabel("Disk #", 10, 20, 50, 17) ;Disk Start Label GUICtrlSetState(-1, $GUI_SHOW) ;Label $Input_DiskStart = GUICtrlCreateInput("", 60, 17, 65, 21, $ES_NUMBER) ;DiskStart Input / Numbers Only GUICtrlSetState(-1, $GUI_SHOW) ;Label $Button_Execute1 = GUICtrlCreateButton("Execute", 10, 60, 50, 25) ;Execute Button on left GUICtrlSetOnEvent(-1, "_Button1") ;Execute button calls the _Button function $Button_Close = GUICtrlCreateButton("Exit", 100, 60, 50, 25) ;Close Button GUICtrlSetOnEvent(-1, "_Exit") ;Close button calls _Exit function GUISetState() While 1 WEnd Func _Button1() Const $wbemFlagReturnImmediately = 0x10 Const $wbemFlagForwardOnly = 0x20 Local $oWMI, $oDrives, $sID, $sName, $iSizeinBytes, $Output $oWMI = ObjGet("winmgmts:\\.\root\cimv2") If IsObj($oWMI) Then $oDrives = $oWMI.ExecQuery("SELECT * FROM Win32_DiskDrive", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly) If IsObj($oDrives) Then For $sDrive In $oDrives If $sDrive.Index = GUICtrlRead($Input_DiskStart) Then $sID = $sDrive.DeviceID $sName = $sDrive.Caption $iSizeinBytes = $sDrive.Size $sIndex = $sDrive.Index ConsoleWriteLine("ID: " & $sID & @CRLF & "Drive Index: " & $sIndex & @CRLF & "Drive Name: " & $sName & @CRLF & "Drive Size in Bytes: " & $iSizeinBytes & @CRLF) EndIf Next Else ConsoleWriteLine("Unable to pull Disk Info" & @CRLF) EndIf Else ConsoleWriteLine("Unable to connect to WMI" & @CRLF) EndIf EndFunc Func consolewriteline($text) ConsoleWrite($text & @CRLF) MsgBox(64,"",$text & @CRLF) EndFunc ;==>consolewriteline Func _Exit() ;Exits Application Exit EndFunc ;==>_Exit Link to comment Share on other sites More sharing options...
