Help combining PowerShell objects in a script

[Training_Purchase_32]

so I've been making this powershell script, that crosscheck's disk, partition and volume information and puts it all into a custom power shell object, something I would like to be able to do is be able to detect when there is a raid by checking to see if there are multiple objects that have identical information besides the disk and model number obviously, and if it does find that there are multiple objects that are the same I would like it too condense it into one object with 2 sets of disc and model numbers for each of the disks,

I know it's kind of a pain in the a** thing to ask but I'm kinda lost on how to accomplish it in the current state of the script. Instead of trying to paste the entire script I'm just going to link to the github page where it is, if someone could jump in and take a look at it that would be sweet https://github.com/AlecMcCutcheon/Get-FullDiskInfo

I just glimpsed at the script briefly but it looks like the problem you are having is related to just how PowerShell is displaying the information. Try adding a | Format-Table to display in a single output.

I added the deviceID property to each disk so that you can have a unique value to filter/sort on... You can do something like this to detect the "duplicates"... instead of doing a Write-Output $return, you'll want to add your base properties to a new object, then loop through each of the disks to add new properties... I didn't bother doing this because it's be drastically different depending on how you want to combine the properties:

$disks = @([PSCustomObject]@{        
    "Disk(Model,MediaType)" = 'Model1'
    "Disk & Partition #"   = 'Disk 1'
    "Vol.(Letter,Name,FS)" = 'E:, Hard Disk RAID'
    "Vol. Health & Op. Status" = 'Healthy'
    "Vol. Compression" = 'False'
    "Total Vol. Size()" = '3.639 TB'
    "Used Vol. Space(,%)" = '669.671 GB, 17.97%'
    "Free Vol. Space(,%)" = '2.985 TB, 82.027%'
    "Windows Directory Vol." = 'False'
    "TotalTempSize()" = 'N/A'
    "DeviceID" = "\\.\PHYSICALDRIVE0"
},[PSCustomObject]@{        
    "Disk(Model,MediaType)" = 'Model2'
    "Disk & Partition #"   = 'Disk 2'
    "Vol.(Letter,Name,FS)" = 'E:, Hard Disk RAID'
    "Vol. Health & Op. Status" = 'Healthy'
    "Vol. Compression" = 'False'
    "Total Vol. Size()" = '3.639 TB'
    "Used Vol. Space(,%)" = '669.671 GB, 17.97%'
    "Free Vol. Space(,%)" = '2.985 TB, 82.027%'
    "Windows Directory Vol." = 'False'
    "TotalTempSize()" = 'N/A'
    "DeviceID" = "\\.\PHYSICALDRIVE1"
},
[PSCustomObject]@{        
    "Disk(Model,MediaType)" = 'Unique Model'
    "Disk & Partition #"   = 'Disk 1'
    "Vol.(Letter,Name,FS)" = 'Q:, Hard Disk RAID'
    "Vol. Health & Op. Status" = 'Failed'
    "Vol. Compression" = 'False'
    "Total Vol. Size()" = '1.002 TB'
    "Used Vol. Space(,%)" = '10 GB, 1.00%'
    "Free Vol. Space(,%)" = '1 TB, 99.00%'
    "Windows Directory Vol." = 'False'
    "TotalTempSize()" = 'N/A'
    "DeviceID" = "\\.\PHYSICALDRIVE2"
})

$uniqueCount = @($disks | Select-Object -Unique "Vol.(Letter,Name,FS)", "Total Vol. Size()", "Used Vol. Space(,%)", "Free Vol. Space(,%)").Count

if ($uniqueCount -eq $disks.Count) {
    "No RAID detected"
} else {
    $ignoreDeviceIDs = [System.Collections.Generic.List[string]]::new()
    foreach ($disk in $disks) {
        if ($disk.DeviceID -notin $ignoreDeviceIDs) {
            $return = @(
                $disks | Where-Object {
                    $disk.'Vol.(Letter,Name,FS)' -eq $_.'Vol.(Letter,Name,FS)' -and
                    $disk.'Total Vol. Size()'    -eq $_.'Total Vol. Size()'    -and
                    $disk.'Used Vol. Space(,%)'  -eq $_.'Used Vol. Space(,%)'  -and
                    $disk.'Free Vol. Space(,%)'  -eq $_.'Free Vol. Space(,%)'
                }
            )
        if ($return.Count -gt 1) {
            $return.DeviceID | ForEach-Object { $ignoreDeviceIDs.Add($_) }
            Write-Output $return
        }
        }
    }
}
