My understanding is that fragmentation doesn’t matter on an SSD: no drive heads, no rotating platters, and therefore no performance degradation. Of course, if you still have an old-style hard drive used for purposes other than backup, there’s a possibility you might have an issue.

When something fails, it just does. If a block or sector becomes damaged in some manner, there’s not really a method by which you can say that it is getting close to becoming damaged. There are some signs you can note that tell you that the drive is either terribly fragmented, or maybe that there is problems somewhere on the disk. These indicators are things like access speed is getting rather slow, or access to one or more files gives you errors. the best, or most reliable way, to fix these errors is, in my opinion, to copy the files over to another drive. As the files move over to the second drive, they are all brought back together and placed on the new drive in an efficient and methodical manner. Once the copy is complete, you can format the first drive. The reformat will clean things up nicely and will also tell you if the it has any errors. There are more secure, or detailed, methods by which you can perform this wipe which would give you more information. A regular erase does not actually erase the entire HD, but you can “zero” everything which would send the print head over the entire drive, thus giving a good indication of whether or not errors are detected. Yes, there may be other tools out there, but I don’t believe that any are really necessary for the vast majority of situations. Just my opinion, of course.
