My unit came with three partitions on the SSD drive, Acer C:\, the EFI System Partition and the Recovery Partition.
It also came with four DVD's, the System DVD, a Recovery DVD, Recovery DVD Disc 1 of 2 and a Revocery DVD Disc 2 of 2.
 
I have a USB3 DVD/CD W/R drive and when I place anyone of the discs into the drive, I'm told that the disc isn't compatable or is invalid.  
 
So my questions are....  
 
If the W700 came with 4 Discs for recovering, what is the Recovery Partition used for?
 
The Recovery Partition doesn't show a drive letter, and "Disk Management" only shows the "Help" when I right click on the partition.  What do I need to do to add a drive letter to the Recovery Partition?
 
If I have the 4 disc for recovering the computer, do I still need the Recovery Partition?  
and if not, how do I free up the disk space?
