Is there any reason to have data-only hard drives set to Protection "On"?

Hello,

Aside from the hard drive space required, is there any reason to not have all hard drives set with protection "On" (in Windows 7)?

Recently I learned that in order to do a System Restore on a particular drive, the System Protection for that drive must previously have been set to "On".  My system has 4 internal and 2 external hard drives. Is there any downside to having all of them set in the "On" position?

I realize that System Restore does not affect data files and as far as I know, my five non-C: drives contain only data. However, is there anything related to extra drives (eg how data is recorded or stored) which might need to be altered during a System Restore?

Thanks

If you want to have the option of a System Restore (which has helped me numerous times by reversing a mistake)  then you need Restore Points.
The only downside I know of is that the hard drive space .  I suggest that you allocate perhaps 2% of hard drive space to Restore Points.
Perhaps of help

since it does not affect data - as you know - i see no reason to set it to on
or are you talking about password protecting the drives?
