A Windows system use an external drive N:.
A programs that use the external drive give sometimes an error message like "Directory N:\datastore is not available".

To test the continuous availability I write the next batch script.

:loop
@TimE /t >> N:\datastore\test_times.txt
@sleep 30
@goto loop

During the night this script stops in cmd.exe with the message: "The system cannot open the device or file specified".
It is intended that this script continues as soon as the disk is available again.
Is it possible to make such a batch script (maybe in powershell) that don't stop, but continues as soon as the disk is available again?

In Powershell it would just be
Code: 
While(-not(Test-Path N:\))
{
    Start-Sleep -Seconds 30
}
# Continue the rest of the script when drive N: is available
