I had a 500 gb hd that was partitioned to 30gb and 470gb (approx). The OEM screwed up doing this, but I was stuck with it. Running Vista the C: drive was filling up even though I wasn't loading anything to it. I purchased a 1TB drive, installed it, backed up the old drive using Acronis True Image Home 2009 (latest build) and restored the info to the new drive. Everything went smooth as glass, but when I go to explorer and look at the new drive it shows: c: 60gb d: 418 gb I'm losing about 500gb/I] Any suggestions, is the space there, but just not reporting?
