Tried

(Get-WmiObject Win32_Volume |select  deviceid) -replace '\D'
# removes all except numbers

here is the cmd

Get-WmiObject Win32_Volume |select  deviceid

deviceid

Try this regex:

(?<=(Volume{))([\s\S]| |w\[0-9]| )+?(?=(}))
or simpler
(?<=Volume{).+(?=})

Even a variant of your try can't work because it would also include the e in volume:

PS> (Get-WmiObject Win32_Volume |select  -expand deviceid) -replace '[^0-9a-f]'
ed0addcdf000000000000100000000000
ed0addcdf000000000000501f00000000

e2367fe0e45e311e6b548806e6f6e6963

Here another working solution using lookarounds:

Get-WmiObject Win32_Volume | Select-String '(?<=\{)[0-9a-f\-]+(?=\})' | ForEach-Object {$_.matches.value}

The first suggestion preserves the `e` from `Volume` (notice how the resulting strings are 33, not 32 chars wide) — Mathias R. Jessen, Sep 24 '17 at 13:14

It appears that you want to capture only the hex digits between the LEFT CURLY BRACKET and the RIGHT CURLY BRACKET.

PS C:\src\t> cat .\dsm.ps1
Get-CimInstance CIM_StorageVolume |
    Select-Object DeviceID |
    ForEach-Object { $_ -match ".*{([-0-9a-fA-F]*)}.*" } |
    ForEach-Object { $matches[1] -replace '-' }

The output is:

PS C:\src\t> .\dsm.ps1
04ec358ff8bc11e3bac6806e6f6e6963
04ec3590f8bc11e3bac6806e6f6e6963
