Just wondering if it's normal for chkdsk on cmd safe mode to go really slow on stage 4 but speed up after? I ran chkdsk on a partition on disk0 and it is at 250gb. Anyway it took too long to get from 7-9%. 3hrs. Then strangely, after that it went to 11%, 15, and so on at a regular speed to me. There were no errors or bad blocks, but that certain percentage just bugged me.
 

as nhasian said, that is normal. Stage 4 takes a very long time, its a surface scan, no matter if theres data there or not,
