I am developing a couple of PowerShell scripts to help speed up the process of migrating user data from an old workstation to a new one. Currently trying to make one to help with retrieving and then deploying mapped network drives and have hit a snagged with the deployment aspect. I am new to PowerShell and learning as I go along using the ISE to help spot some of the problem areas the script has. Here is a copy of what the script currently looks like and the error I am receiving when trying to run it on the machine.
# Import drive list.
$mappedDrives = Import-Csv C:\Users\########\Desktop\WIP_Scripts\MasterCopy\mappedDrives.csv
$mappedDrives | %{$_ -replace ":"}
foreach ($Name in $mappedDrives) {
New-PSDrive -Name $Name.Name -PSProvider FileSystem -Root "ProviderName" -Persist -ErrorAction Continue
}
Once I have it working Ill make the edits for where the import comes from. The errors I am currently receiving are:
New-PSDrive : Cannot process the drive name because the drive name contains one or more of
the following characters that are not valid: ; ~ / \ . :

For the script used to retrieve the drive information:
$mappedDrives = @()
$Name = Get-WmiObject -ClassName Win32_MappedLogicalDisk | Select Name, ProviderName
foreach ($Name in $Name) {
if ($Name. ProviderName) {
$mappedDrives += Select-Object Name, ProviderName -InputObject $Name
}
}
$mappedDrives | Export-Csv mappedDrives.csv
Also attached is what the mappeddrives.csv output looks like for the retrieval. I thought that the csv file may be causing the invalid character arguements since the Name found within the csv file includes the ":" character. Also I am a bit confused on whether or not it will be able to see the "ProviderName" within the csv file or if I need to declare it in order for the script to add it to its argument. Again I am extremely new to Powershell so lots of what I have written down is what I have found from this site, Microsoft, or other blogs/forums and trying to Frankenstein together a working script. Any feedback on how to improve or get this to work and/or why using another method would be better in this situation would be greatly appreciated.
###Revision 1###
Utilizing the new script provided by RetiredGeek
# Import drive list.
$CFSArgs = @{PropertyNames = "Name", "ProviderName"
Delimiter = ','}
$MappedDrives = (Get-Content "G:\BEKDocs\Scripts\Test\mappedDrives.csv") |
ConvertFrom-String @CFSArgs
for ($cnt = 1; $cnt -lt $MappedDrives.count; $cnt++) {
$NPSDArgs =
@{Name = $(($MappedDrives[$cnt].Name).Substring(0,1))
PSProvider = "FileSystem"
Root = "$($MappedDrives[$cnt].ProviderName)"
Persist = $True
ErrorAction = "Continue"
}
New-PSDrive @NPSDArgs
}
I am now receiving the following error:
New-PSDrive : When you use the Persist parameter, the root must be a file system location
on a remote computer.
At C:\Users\######\Desktop\MasterCopy\Test2.ps1:16 char:9

+ ~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidArgument: (":PSDriveInfo) [New-PSDrive], NotSupported
Exception

riveCommand
The two questions I have now are:
- Would it be more appropriate to use "Net use" instead of "New-PSDrive" for what I am trying to achieve(which is mapping a network drive to a computer using the cvs file created)?
- If the use of the New-PSDrive cmdlet is a non-issue how do I rectify the error the script is currently outputting?
Thanks again to RetiredGeek and Theo for your inputs.
-NoTypeInformationto theExport-Csv mappedDrives.csv. This will prevent the top line with field type description to be written that is causing the problem.
