I looked in disk manger in Win7 and am seeing a 200mb hidden NTFS partition on HDD that I installed Win7 to that has 31.9mb used of 200mb. Has a long catalog number and says 'system, active, primary partition'. C: comes after that partition and says 'boot, pagefile, crash dump, primary partition'. Is that where Win7 puts system files backup in case of C: crashing or what?
