Remove Windows System File Protection From 2nd Disk?

Less than a month ago I build a new rig, installed Windows 7 on my SSD and at a later time I attached my old 1TB large disk with still had XP installed on it.Windows is protecting this drive, all folders are flagged read only and I'm unable to remove the read only flag, each time I try, and check back after processing a job to un flag it, there still there.I'm able to delete files and folders after accepting the UAC popup, however, there are several folders I want to remove but am unable to, /Boot, /Documents & Settings, /Windows and some root system files, but windows doesn't let me.(I need to run programs with elevated rights in order to be able to modify those files) The /Boot is from an older Windows 7 install and it should be safe removing it, because I installed windows 7 on a SSD with out any other disks attached, so no dual boot stuff.But worst of all, many files are also flagged read only, along with my project files that I'm now unable to modify.What buttons do I need to press to get windows to understand he should not be protecting this disk and there ain't no windows installed on it so I can clean up get rid of those read only flags on the files
