How to show a hidden partition? - (Moved)

[BlueSkyMemory]

Hello guys! I'm a rookie in AutoIt lol.

I've tried to looking up in MSDN and the UDFs, but it can only get the GUID of a usual partition and with the GUID to control it. Now I have no ways😥.

Thanks a lot for your help!

Have you tried Win32_DiskPartition class ?

Maybe try this?

Thanks a lot!

But in WinPE, it is not able to use Powershell and WMI.

Thanks, it works fine! But it's a pity that it doesn't support GPT disk.

What about diskpart ?

You will need  to add\build in the ms scripting package "WinPE-Scripting.cab" to your winpe to make it work

"WinPE-PowerShell_en-us.cab" and more,  Here are all or more packages that you can add in starting from a clean boot.wim @line 1 using the ADK

Dism /Mount-Image /ImageFile:"C:\WinPE_amd64_PS\media\sources\boot.wim" /Index:1 /MountDir:"C:\WinPE_amd64_PS\mount"

                Dim $LogicalDisks = $Services.ExecQuery("Associators of {Win32_DiskPartition.DeviceID='" & $DiskPartition.DeviceID & "'} Where AssocClass = Win32_LogicalDiskToPartition")
                For $LogicalDisk In $LogicalDisks
                    If $LogicalDisk.DeviceID = $var[$i] Then
                        $specifs[$i - 1][0] = StringUpper($var[$i])
                        $specifs[$i - 1][1] = $DiskDrive.Caption
                        $specifs[$i - 1][2] = Round(DriveSpaceTotal($var[$i]) / 1000)
                        $specifs[$i - 1][3] = Round(DriveSpaceFree($var[$i]) / 1000)
                        $specifs[$i - 1][4] = StringFormat('%.2f', $LogicalDisk.Size / (1024 ^ 3)) & ' GB'
                        $specifs[$i - 1][5] = $DiskPartition.DeviceID
                        $specifs[$i - 1][6] = $LogicalDisk.VolumeName
                        $specifs[$i - 1][7] = $DiskPartition.Type

Yes, I can use Diskpart and StringRegExp to make it work. But for compatibility and smaller size, I want to use API instead of other modules.

Thank you! I've saved it in my disk lol. But it still depends on so many modules. And it cannot detect hidden partitions.

I've found your code is so powerful! By the way, could you please help extract the part that determines whether it is an active partition? Thanks a lot! (To ensure which partitions can be booted)

Edited April 12, 2020 by BlueSkyMemory

[RTFC]

Thanks. To make a partition bootable (NB: only one (1) partition can be bootable per physical drive, so you always need to edit two flags, not one), look for, and edit boolean IsPrimary (any non-zero value = True; usually 0x01 or 0x80); it's the first byte of each partition table entry in the MBR. In the UDF, see var $partition_active in Func _ReadPartitionEntry for more info.

WARNING: any changes you make to these low-level descriptors is entirely your own responsibility. Please ensure you back up your entire physical drive (not just the files on it), before you start tampering with it. In this particular case, editing a single byte can result in your system no longer booting at all, and no easy way of fixing it. Only proceed if that scenario does not concern you at all.

I've got it! And do you know how to show a hidden partition? I mean, to give a letter to it.

[RTFC]

Assigning drive letters has got nothing to do with physical drives; you need to look into SetVolumeMountpoint for that.

To hide/show logical volumes, see the remarks section of the UDF:

- hide/unhide logical volumes (simply set/reset bit4 of a volume's Partition_Type in its (E)MBR partition entry)

OK, I've got these APIs. Now I can use FindFirstVolume and FindNextVolume to get all GUIDs, and then assign letter to them. But when I try to use Find First/Next VolumeMountPoint  to find out its letter, I failed (actually it can only get the mountpoint I set to, not the drive letter.)

@BlueSkyMemory, The comment I made in your other thread was also meant for you! 

Do NOT quote each and every post you reply to, as that information is already there, so just reply with your answer unless there is a real need to quote something!

[BlueSkyMemory]

Sorry that I don't know the rules clearly. I've got it!

[BlueSkyMemory]

OK. Now the problem is solved. Thanks to everyone! This is my code below, hoping to help others--

Func _GetVolumeMountPoint($sGUID)
    $tPathName = DllStructCreate("char[2048]")
    $aResult = DllCall("Kernel32.dll", 'bool', 'GetVolumePathNamesForVolumeNameA', 'str', $sGUID, 'str', $tPathName, 'dword', DllStructGetSize($tPathName), 'dword', DllStructGetPtr($tPathName))
;~  _ArrayDisplay($aResult)
    Return $aResult[2]
EndFunc
