Sure, but Apple won't replace anything if their tests indicate it's OK. What I really think is that no one knows. Everyone's needs are different, but if you ever find yourself in a position where the prospect of losing any one particular hard disk at any given time causes the slightest concern, then you have to reevaluate your backup strategy. Taken to a logical conclusion no spinning hard disk should be relied upon. That's one of several reasons one and only one backup is not sufficient. If a disk is faulty it can be used to failure but should no longer be relied upon. In my opinion there are no hard disk "scan" utilities worth anything, although if Disk Utility indicates a failure it is likely to exist. I understand problems existed before you did that, but it just compounds the uncertainty. Selectively restoring individual items is likely to be unaffected though. If nothing else it is almost certain to render a complete system restoration impossible. I wasn't aware any backup dates were manually removed, which is certain to corrupt a TM backup and hinder its usefulness at best. Until it froze, I could log in and see the progress. I tried Control+Shift+Eject but that did nothing. Then I am going to force shut down with the on/off button in back, and restart it.

So I am going to wait 3 more days when it "should" have finished. I don't want to interrupt it if it is really working. I can't get anything to respond so I don't know if it's still copying over the files. The Time Machine is still working (blinking on and off as it looks like it's processing files) but the screen saver is just frozen there. Finally it started copying and got 1/2 done and my screen saver froze. It took 5 days (lots of files) to PREPARE the files for copying. Then because the data on Time Machine backup was not accessible (what a surprise - it's never worked for a restore for me) the Apple store agent suggested I go in to Time Machine through the back way and copy over the USER file as a new user on my now, empty Mac. The Apple folks (I took the computer and Tie Machine into the store) suggested that I wipe everything, which I did. Just wanted to add closure - well, it's still in the middle of closure a month later.
