Can I or can I not run a defrag program?

I just installed CTM… I read one (1) post where it says doing a defrag on Win & is a waste of time? Does this mean I CAN NOT do a defrag of my primary partition where Win 7 is?

When CTM is installed do NOT run defrag programs

May I ask the reasoning behind this restriction? (I looked and couldn’t find anything about it).

Are there any docs that mention other things I can’t do with CTM?

not that im aware of but the only things that i can think of is dont use disk/registry defrag and dont use other software that needs to control the mbr like other snapshotting tools or truecrypt

You also don’t want to use System Restore.

the FAQ needs to be updated. it says that defrag tools are ok to use
