First of all, thanks so much to whoever tries to help me. My hard drive is 2TB in total. I'm trying to add 10GB to system drive C from drive D (800GB left). After applying all changes made, I got a message saying reboot needed because certain files are in use... but I clicked "what files..." nothing found. http://p13.freep.cn/p.aspx?u=v20_p13_photo_1206052232489616_0.jpg I clicked retry and then the op seemed to be started. After about 15 mins this is what I get, the timeleft is 23+ hours! http://p13.freep.cn/p.aspx?u=v20_p13_photo_1206052236031457_0.png Is this normal? or something wrong is happening... I then tried to abort the op but it says data will be lost... is this for real? Do I really have to wait for 23 hours or is there something else I can do? Thanks again!
