A while back I was presented with the following problem during a Operating System Deployment Project. If a computer had a multi-card reader it would assign itself to the following 7 drives:
- E:\
- F:\
- G:\
- H:\
- I:\
- J:\
- K:\
This wasn’t so much a problem, except that the Drives H:\, I:\, J:\ & K:\ were used for Network locations and as a result those drives did not map via the logon script. So I had to move the Multi-Card reader off those drives.
It was decided that we would move the whole lot and not just the ones that were conflicting as this would enable us to create a standard deployment strategy.
So I wrote a script that would move all removable drives off the lower level drive letters and move them up the alphabet to a section that wasn’t quite so populated.
I then added this script to a SCCM Package and deployed it through the Task Sequence. When the machine was built the Multi-Card reader would start at “O:\” and not “E:\”.
Simple solution, works very well. Hopefully someone else will find some value in this.

Hi Chris,
Your script looks very good, excelent JOB.
Could You help me With the runing the script ?
I have tried to use/run but script ended with error about line 53. When I try to comment this line script doesn’t finish with error but writed to Log file >

For some reason it thinks all your drive letters are taken. What drive are you trying to start from?
