.SYNOPSIS
```

Display the SMART status for all local harddisks in a popup window and in Windows' Notification Area (a.k.a. System Tray)

```
 
```
```
.DESCRIPTION
```

This script uses WMI to query the status of all local physical harddisk drives, and displays the results in a popup window and in Windows' Notification Area (a.k.a. System Tray).

In the status display, each physical harddisk is associated with the drive letter of one of its volumes.

Since Windows 10 limits the number of lines in desktop notifications, any errors will be placed at the top of the displayed status list, otherwise the list is sorted by drive letter.

If all disks report OK, the script returns True and return code ("ErrorLevel") 0, otherwise False and return code 1.

Since this script uses WMI and drive letters, it will not work in Linux.

```
 
```
```
.PARAMETER Modal
```

Make the popup window always stay on top

```
 
```
```
.PARAMETER Hide
```

Hide the console window when the script is started, restore it (but minimized) afterwards

```
 
```
```
.PARAMETER Version
```

Show this script's version number; if combined with -Verbose show full script path, version number and last modified or release date

```
 
```
```
.PARAMETER Debug
```

Display intermediate results for each disk drive in console; if combined with -Verbose show intermediate results for each associated volume too

```
 
```
```
.PARAMETER Help
```
```
Show this script's help screen
```
```
 
```
```
.OUTPUTS
```

True and return code 0 if all disks report OK, otherwise False and return code 1

```
 
```
```
.EXAMPLE
```
```
. ./GetHDDStatusGUI.ps1
```

Will display a popup window with the drive letters in use and the SMART status of the associated physical harddisk drive.

```
 
```
```
.EXAMPLE
```
```
. ./GetHDDStatusGUI.ps1 -Debug -Verbose
```

Will list details for all physical harddisk drives and volumes in the console, and display a popup window with the drive letters in use and the SMART status of the associated physical harddisk drive.

```
 
```
```
.EXAMPLE
```

. ./GetHDDStatusGUI.ps1 -Version -Verbose

```
 
```

Will display this script's full path, version number and last modified or release date.
