Batch File for Win7 PE

I have the following code in a batch file to help me find a USB drive. This batch file looks for a directory that I placed a folder on the USB drive to help with the search. Generally the USB letter is unknown so rather than just fumbling around and entering letters until I stumble upon the right one I have found this bit of code to put in the batch.

I am wondering if there is a way to use the result "%%d" in a variable to finish off the batch by going to the found drive. I tried just using %%d: to try and change to the Found Drive but that doesn't work.

Note that this works really well in the PE but throws a fit in Windows 7. ( you get about 4 "No Disk" Errors which is not really a problem because I know it works in the PE environment)

Thank you for any advice and help you can send my way.

  
@echo off
setLocal Enabledelayedexpansion

for %%d in (c d e f g h i j k l m n o p q r s t u v w x y z) do (
  if exist %%d:\B75_hp\ (
     ECHO USB Drive Has Been Found at : %%d
  )
)

This code finds the first removable usb disk without that much effort:

@ echo off
For /F "tokens=1" %%I In ('wmic logicaldisk get DeviceID^,DriveType^|Findstr "2"') Do (
If Exist "%%I\B75_hp\" (
echo Disk found at %%I
)
)
pause

Thank you

This code does basically the same thing. But thank you.

What do you mean by saying "Finish off" ?
Do you want the batch to open the drive in explorer or change the command prompt working directory to that drive?

By finishing off I mean I would like the that filed automatically go to the drive. For example if the directory is located on the USB drive and has been found at "M" then a variable would be set up so that the last command in the batch file would read M:

Keep in mind are working in a preinstall environment not Windows so all we are dealing with is a DOS prompt.

Thanks For your Help.

Thank you all for your help. Both of the variations work just fine. I dropped them into the CD and booted into the PE and shazam no more fumbling around looking for the USB Drive.

Thank you
