Convert my Get-HDSizeInfo Cmdlet Output to a CSV File

Earlier this morning I posted some code that will extract hard drive information from other clients on your network.  I got this idea from a user on the LinkedIn group PowerShell Power Users.  His request was for a CSV file where my code sent objects into the pipeline that would not translate well into a CSV.  Below is the code that will convert the output of that cmdlet into a CSV. 

To use this code:

  1. Copy the Get-HDSizeInfo code from my previous post into the PowerShell ISE. 
  2. Paste the code below directly under the Get-HDSizeInfo code
  3. On line 81, provide the names of the clients that you want to pull the hard drive information from.
  4. On line 82, update the Path parameter to where you want the output file to be.
  5. On line 82, adjust MaxDrives to the highest number of drives you expect any 1 client to report.  It defaults at 3.
  6. Run the script.
