Chkdsk error

I recently restarted my computer, and when booting into Windows the OS decided to run Chkdsk (at least I believe it's Chkdsk) on my second HDD with the message "The volume is dirty" (it has not yet loaded the windows manager). So it runs for a bit, then at 98% completed says

"Windows replaced bad clusters in file \foo\bar\...
\...\filename.pdf
of name (null). "

And then it stood there for like an hour.

Now the same kind of message has appeared again under the first (but for a different file, though in the same directory), and beneath that it continues to report "98% complete. "

These .pdfs are a batch I had just moved into the directory, so there may be another one or two that are similarly corrupted.

Is my drive going to be at all recoverable? Any idea how long this is going to take to finish? Is there any way to tell if it has hanged? What are the dangers of a hardware forced reboot during this process if it has hanged?

Thanks.

 

Bad clusters means that there is a physical problem with the surface of the drive's disk/s.

My suggestion:
If the the files have been copied or backed up I suggest deleting them (highlight, hold down the Shift key and press Delete so they are not sent to the Recycle Bin). After that, run CheckDisk in Safe Mode.

Run chkdsk /r from Safe Mode Command prompt.
