Retrieving the amount of local storage on a device in UWP app

I have been trying to find the amount of free storage space available in the fixed drive on a device in my UWP app. I have been using the following code to achieve this-
DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
{
if (d.DriveType == DriveType.Fixed && d.IsReady)
{
double availableFreeSpaceInBytes = d.AvailableFreeSpace;
}
}
But whenever I run this, d.IsReady always returns false indicating that the device is not ready. I referred this- https://learn.microsoft.com/en-us/dotnet/api/system.io.driveinfo.isready?view=netframework-4.8. But haven't been able to understand.
Please help me with what am I doing wrong. Or is there any other way to achieve this?

If you only need to know the free space on the drive where your UWP app is installed (usually, the C: drive), you can use the following without adding any additional capabilities:
using Windows.Storage;
string freeSpaceKey = "System.FreeSpace";
var retrieveProperties = await ApplicationData.Current.LocalFolder.Properties.RetrievePropertiesAsync(new string[] { freeSpaceKey });
var freeSpaceRemaining = (ulong)retrieveProperties[freeSpaceKey];

Retrieving the amount of local storage on a device in UWP app
AvailableFreeSpace is not available in UWP system. For getting available free space, you need use StorageFolder System.FreeSpace property to achieve. Pleas note if you used GetFolderFromPathAsync metod, you need to allow broadFileSystemAccess capability before. Please refer this case link.
const String k_freeSpace = "System.FreeSpace";
const String k_totalSpace = "System.Capacity";
DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
{
try
{
Debug.WriteLine("Drive: " + d.Name);
Debug.WriteLine("RootDir: " + d.RootDirectory.FullName);
StorageFolder folder = await StorageFolder.GetFolderFromPathAsync(d.RootDirectory.FullName);
var props = await folder.Properties.RetrievePropertiesAsync(new string[] { k_freeSpace, k_totalSpace });
Debug.WriteLine("FreeSpace: " + (UInt64)props[k_freeSpace]);
Debug.WriteLine("Capacity: " + (UInt64)props[k_totalSpace]);
}
catch (Exception ex)
{
Debug.WriteLine(String.Format("Couldn't get info for drive {0}. Does it have media in it?", d.Name));
}
}

Retrieve Hard drive info through WMI .NET C#

So i've used this code to get S.M.A.R.T. hard drive diagnostics info from Windows WMI:
http://vasters.com/archive/Reading-ATAPI-SMART-Data-From-Drives-Using-NET-Temperature-Anyone.html
It works on most computers and doesn't on others. After a little bit research and sample testing i found out that it doesn't work on computers whose Hard drives are connected with PCI Express instead of SATA.
var searcher = new ManagementObjectSearcher("root\\WMI", "SELECT * FROM MSStorageDriver_ATAPISmartData");
foreach (ManagementObject queryObj in searcher.Get())
{
//do stuff
}
This is where i get exception:
System.Management.ManagementException: 'Not supported'
Is there any other way to do this, or add something in this code to make it work?

I searched this code everywhere and couldn't find working for me, but finaly found on another forum so it's really simple in usage.
Just from my example another way to get WMI info. More Attributes of WMI Win32_DiskDrive you can find in Microsoft DOCs
https://github.com/Mityugin/greentest
string NamespacePath = "\\\\.\\ROOT\\cimv2";
string ClassName = "Win32_DiskDrive";
oClass = new ManagementClass(NamespacePath + ":" + ClassName);
foreach (ManagementObject oObject in oClass.GetInstances())
{
var sign = Convert.ToString(oObject["Signature"]);
var model = Convert.ToString(oObject["Model"]);
var status = Convert.ToString(oObject["Status"]);
if (Equals(sign,""))
{
TextBox1.AppendText("DISK model: " + model);
TextBox1.AppendText(Environment.NewLine);
TextBox1.AppendText("Status: " + status);
TextBox1.AppendText(Environment.NewLine);
if (!status.Equals("OK") || !model.Contains("SSD"))
{
//Here is info if Disk is not OK or model not SSD
}
}
}

This github solution is fine for detecting an SSD but will not tell you it is PCIE or NVMe. I have an SSD that is an older Samsung 960 series and it is an SSD connected via SATA.
The code you need to read an NVMe drive Temperature is on this website at How do I enumerate NVMe (M2) drives an get their temperature in c#?

Display General tab information of property window of local disks in my computer

I need to access the type of disk and display it in the C# code. In this image "
Local Disk Image" the type is local disk.
In this image "Cluster Disk Image" the type of disk is cluster disk.
I have used driveInfo class to get the drive details. but I'm not able to display whether the drive is cluster or local disk. d.DriveType returns whether it is a removable or fixed types. and not the required local disk or cluster type.
My code is added below:
DriveInfo[] allDrives = DriveInfo.GetDrives();
foreach (DriveInfo d in allDrives)
{
Console.WriteLine("Drive {0}", d.Name);
Console.WriteLine(" Drive type: {0}", d.DriveType);
if (d.IsReady == true)
{
Console.WriteLine(" Volume label: {0}", d.VolumeLabel);
Console.WriteLine(" File system: {0}", d.DriveFormat);
Console.WriteLine(
" Available space to current user:{0, 15} bytes",
d.AvailableFreeSpace);
Console.WriteLine(
" Total available space: {0, 15} bytes",
d.TotalFreeSpace);
Console.WriteLine(
" Total size of drive: {0, 15} bytes ",
d.TotalSize);
}
}
Is there any way to display the required info in C# code?
Thank you.

How to get Total HardDrive available and used cpace in c#?

I have below code to get individual drive's information but I want the whole HDD informationie.I.E. total size and used or available space
public List<DriveInformation> GetDriveInfo()
{
List<DriveInformation> info = new List<DriveInformation>();
DriveInfo[] drives = DriveInfo.GetDrives();
foreach (DriveInfo drive in drives)
{
DriveInformation temp = new DriveInformation();
temp.driveName = drive.Name;
temp.driveSize = drive.TotalSize.ToString();
temp.availableSize = drive.TotalFreeSpace.ToString();
info.Add(temp);
}
return info;
}
if I have an unallocated drive then drive info unable to show that space.
ex: I have 500GB HDD and there is 2(C & D) partitions 200 each then this function give only infromation about C and D. I also want the Unallocated space detail(I.E.another 100GB) whether it is used or unallocated.

How to lookup Hard Drive model with C#?

In part of a program I am writing, I'm trying to pull device information about specified local hard drives. I've been able to create a few value returning methods using the DriveInfo class like this:
//Gets drive format
public string GetDriveFormat(string driveName)
{
foreach (DriveInfo drive in DriveInfo.GetDrives())
{
if (drive.IsReady && drive.Name == driveName)
{
return drive.DriveFormat;
}
}
return "";
}
//Example of use
MessageBox.Show(GetDriveFormat("C:\\"));
The problem I'm running into now is that there doesn't seem to be a Model property to the DriveInfo class. I've looked all over but am unable to find a way to construct a value returning method that will return the model of a drive like what is viewable in device manager.
Any help would be greatly appreciated,
Thanks!

Unfortunately, you cannot get the Drive's Manufacturer and Model using the DriveInfo class.
You'll have to resort back to WMI:
WqlObjectQuery q = new WqlObjectQuery("SELECT * FROM Win32_DiskDrive");
using (ManagementObjectSearcher res = new ManagementObjectSearcher(q)) {
foreach (ManagementObject o in res.Get()) {
Console.WriteLine("Caption = " + o["Caption"]);
Console.WriteLine("DeviceID = " + o["DeviceID"]);
Console.WriteLine("Decsription = " + o["Description"]);
Console.WriteLine("Manufacturer = " + o["Manufacturer"]);
Console.WriteLine("MediaType = " + o["MediaType"]);
Console.WriteLine("Model = " + o["Model"]);
Console.WriteLine("Name = " + o["Name"]);
// only in Vista, 2008 & etc: //Console.WriteLine("SerialNumber = " + o["SerialNumber"]);
} }
Not sure if you need to consider mounted drives as well:
foreach(ManagementObject volume in new ManagementObjectSearcher("Select * from Win32_Volume" ).Get())
{
...
}

You'll need to use a lower-level API to get this information, and even then it still might not be accurate.* The internal details of the hard drives is exposed in the Win32 APIs, which you can still access in C# through WMI.
*: Note that this is still limited to the hardware information as Windows is able to see it. In some conditions, it won't or can't be accurate (e.g. with a RAID array, where Windows sees N drives as a single drive).

I'm not entirely sure if you can get that info without using lower level api's. This post should help you achieve your goal.

Quick summary of the link:
Add a reference to the System.Management library
Then you can use:
var disks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach (ManagementObject disk in disks.Get())
{
Console.WriteLine(disk["Model"].ToString());
Console.WriteLine("\tSerial: " + disk["SerialNumber"]);
}

here is something that can also work for you feel free to tweak it as you please
String drive = "c";
ManagementObject disk = new ManagementObject("Win32_LogicalDisk.DeviceID=\"" + drive + ":\"");
disk.Get();
Console.WriteLine(disk["VolumeName"]);
foreach (var props in disk.Properties)
{
Console.WriteLine(props.Name + " " + props.Value);
}
Console.ReadLine();
