a batch script file to find the number of disk attached to the system , run the batch file in n number of disk. run the batch file on all the removable disks and exits.
 
Thanks in anticipation

Solution 1

Basically, it all is done via WMI: http://en.wikipedia.org/wiki/Windows_Management_Instrumentation[^].
 
In PowerShell (highly recommended):
 
$drives = Get-WmiObject Win32_Volume | Where { $_.DriveType -eq 2 }
Here, drive type 2 means "removable drive"
 
In legacy batch:
 
@wmic logicaldisk get volumeName, description, deviceId

 
Add some code to count them.
 
Please see:

Good luck,
