Ipod says "scan drive now to fix it" when connected to Itunes

How do I find the replies to the question?

There do not seem to be any replies, except for your reply. What is your actual question?

The problem that I have with a nano 5th generation ipod is: when I try to sync a cd that is on my computer to my ipod there is blue heighted statement that says "There is a problem with this drive. Scan the drive now and fix it." How do I scan the drive and then fix it?

I think that may be an error message from Windows, not from iTunes. If there is a problem with the "drive" (which is the iPod's storage in this case), it's best and easiest to do a Restore on the iPod using iTunes. This erases the iPod, reinstalls its software, and sets it to default settings. The Restore button is on the iPod's Summary settings screen in iTunes.

Use iTunes on your Mac or PC to restore your iPhone, iPad, or iPod to factory settings - Apple Support

After the Restore, try syncing your music back.

I uninstalled iTunes and reinstalled it. Now all my music is still on my ipod, but when I try to put a new cd from the computer on to my ipod it wont do it. There use to be an option " add to" then I selected my ipod. This option is not there. I can play it on the computer, but I can't transfer it to the ipod.

So, I guess you are now passes that error message...

Loading new songs on an iPod depends on its current setting; whether it is set up to load songs manually, or by using automatic syncing. To check, select the iPod in iTunes (click its device button on horizontal bar) to show its Summary settings screen in iTunes window. There is a checkbox there for Manually manage music and videos. Without changing the current setting, is that checkbox currently checked or not checked?

The manual box is checked.

Your iPod is set to load songs manually. Show your iTunes music library (click Music button at left end of horizontal bar). Near middle of horizontal bar, click Playlists. A sidebar appears along left side of window, with your iPod listed under Devices. Choose a view for your music library using the control at right end of horizontal bar. I usually use the Songs view, to show a plain song list with columns. But in this case, if you want to load "a new CD" (an album), you can use the Albums view. Scroll the library to show that new album's artwork tile. Click-hold-drag the album (by its artwork) to the sidebar, and drop it on your iPod. The album's songs are loaded on the iPod. You can do this with one or more individual songs selected, instead of a complete album. Alternately, instead of dragging/dropping, right-click the selection and Add to Playlist -> [Name of iPod].

To check if the songs are loaded, in the sidebar, click the small triangle to the left of the iPod, to drop down the iPod's content list (indented below iPod). Click Music on the iPod's content list. To the right, the iPod's current song list is shown. Confirm that the new songs are there. You can also use this song list to manually remove songs from the iPod; select a song you want to remove and press Delete on the keyboard. You can do this with more than one song selected.
