Will CHKDSK Harm My Files?

//
I recently did a CHKDSK scan on two hard drives with video files. The first scanned with no options checked. It did not show any details of progress except the progress bar. It got to the end and then froze (although the computer did not freeze) and the only way to exit it was to shut down the computer or reset. Do you think any of my video files got corrupted or changed in any way? With the other hard drive, I scanned four times without errors. On the fifth time, I scanned it on another computer and it said that it had a file system error. Needless to say, I did not fix that. I don’t know if one of the four times before I checked any options, but I’m thinking I had nothing clicked. Is it possible that my video files on the hard drive got corrupted or changed in any way, even if I had clicked one or both of the options?

You may have problems with your video files, but I don’t think it’s because of CHKDSK. Without any options selected, the CHKDSK utility simply reports the current status of your hard drive.

But there are a couple of interesting things about CHKDSK that I think are worth reviewing here.
