your loop changes the value of driveletter
26 times (the first 25 times overwriting the 
old value).   after the 26th and final iteration
what is left in driveletter is the last thing
you put there.   As written, that will be 'Z:\'.

this is correct behaviour, but probably not
what you intend.

thread]
