Does it check current volume or does it check every volume (full drive)?
I read somewhere that without letter it works on current volume (so c: if I run it from c:/) so I decided to be fancy and run it like this for checking c: (I have disk problem and previously chkdsk fixed them). But now it is running for far too long, recently I run it on c: it was for 1-2 hours and now it is >5 hours. Not sure is it checking everything or is my disk having problems.
Can't google it out because of "how to run chkdsk on volume without letter".
