First, Welcome Anderdea............just for the ROG of it.
The short answer is NO. The longer answer is NO WAY.
If you delete a blank partition, it simply becomes unpartitioned space, if you repartition it, it will be next drive letter (usually)
Start seperating 'files' from 'programs'...(not program files...no offense)
Storage should be on your partitioned drives....ie..music, graphics...zip files.
Load your programs to C....If this becomes an issue (too full)..they can always be loaded in the partitioned drives..(other than c)
Chances are the 'hidden recovery' contains the same setup....unless the second drive was an add on..
It is more about file/folder management than partition management at this point.
There is always wiping the drives (If you have win7 disc)...but this deletes your recovery partition.
You could also (if you have win7 or other os disc) format c: and reload it...also not for the meek.
As I read you last line again....Id say....just move files from c: and keep it clean....use storage for, well, storage.
Best of Luck...keep us posted..we love a good success story here...
It gives the haters something to grumble about and the rest of us pleasure from the time well spent here. enjoy.c.
