问题
this code almost works, it maps VWare VMDK to windows drives. The code is not mine.
Among other info it will return "DD-SERV-01_15.vmdk for VM MAIN is Drive letter G:"
The script will prompt for credentials and proceeds to map however something goes wrong and only the last VM / Drive is is saved as output - I was hoping someone could take a look and update / fix the code so that it saves all output please?
Thanks.

Try adding the -Append parameter to your export-csv, so it does not overwrite the last entry:
$myCol | Export-Csv -Append -NoTypeInformation 'C:\TEMP\VMwareDiskUsage.csv'
