Remove 'Recycler' and 'System Volume Information'

Archived from groups: microsoft.public.win2000.setup_deployment (More info?)

Hi,

last week I had a blue screen of death on my Windows 2000 standard server
with SP4.
I had to reinstall the system.

I restored the C-Drive and D-drive from tape created with NTBACKUP to a new
folder on another disk on that server, just to verify if I had everything in
place.

Now I want to remove those restored drives but Windows won't let me.
If I look into these 'restored' folders I see a 'Recycler' and 'System
Volume Information' folder (hidden).

My questions are:
Is there a way to delete these system folders?
Is it safe to delete these system folders?

thanks,

Pasquale
