Slave Hard Drive : "Copy System Files" to make it bootable needed?

[DUD]

I've added a second hard drive to a system for the purpose of holding audio and video files. The operating system and apps are on the other hard drive. The slave is a Western Digital; I used the Data Lifeguard Tools to install, partition and format the drive. The mobo supports this size drive so no "EZ BIOS" was needed or used. I note that system files have been copied to this drive to make it bootable. I have no interest in adding a second operating system. Should I leave these files? Any harm in deleting them?

If you are never going to use the new drive as the Primary Master, then delete the system files. I always like to keep both disks bootable in case I need them.
