I have a problem, last week i looked in my hd and there was 207gb free space, i always try to keep my hd clean so not to clog it up with rubbish i dont need. I looked again today and there is 178gb free! I ran a diagnostic on the hd utility that says 53.8gb used from a 232gb on the hd. i then ran jdiskreport which has told me that i have used a total of 19.8gb which means i have 30gb uccounted for?! Has anyone any ideas where it has gone?
