The easiest approach at first is to run a
chkdsk /r, that includes an examination for bad sectors. Chkdsk then recovers the data from the bad sector and rewrites it to good sectors. It then marks the sector bad so that data is not rewritten to it.
Contrary to popular belief chkdsk does NOT repair bad sectors. It cannot do so.
A sure sign of a failing disc is when bad sectors are found on a chkdsk run and then the dirty disc bit is set and chkdsk runs automatically on boot.
I have at the moment not time to examine all the thread again, but will do later.
For the time being run a chkdsk /r at the command prompt, that is start, run type
cmd, when the window opens type at the C: prompt
chkdsk /r Note the space between the chkdsk and the /r.
Agree the message to run on restart.
Then go Control Panel, Admin Tools, event viewer, Application on left pane and scroll to the winlogon entry in the main window. Double click to open that and check that it is the chkdsk results.
On the right hand side below the up/down arrows is a double page symbol, click once that is the copy.
Then on your reply right click and paste.
Your chkdsk results will appear in the reply message.
Do this as soon as the computer reboots.
That Drive Fitness test will run

on that drive.
CAUTION a drive fitness test subjects the drive to a certain degree of stress. If your drive is FAILING, it may be better to create a complete image of the drive first, although that in itself is also asking the drive to work hard.
However it is a catch22 situation and there is no easy solution.
My advice - run the chkdsk as posted - confirm if bad sectors. If so take immediate action to do as advised.
