A cluster is not a file, but a physical division of the drive's storage space.
Bad clusters don't function correctly and thus can't be read or written to correctly. Looks like Windows was able to recover the affected file and move it somewhere else (physically) on the disk.
You can't fix bad clusters. They're gone for good. But you can partition the hard drive around them so that they're no longer an issue. Unfortunately, oftentimes bad clusters means further hard drive failures are imminent.

sysevent.evt is a "crash log." It's not a critical thing but, as Paul said, even if it was it wouldn't be a big deal since Windows was able to recover it. The crash log is just there for you to examine if you want to find out specifics about a windows crash (not necessarily related to that hard drive failure...could be left over from an old windows crash).

I've heard that it's longevity is quite high, especially when compared to HDD. Many are quoting 10+ years now and much more depending on the situation. In a server environment where a majority of the activity is reading data, the longevity is considerably higher since there is only limitations on write cycles (not that this is a huge issue, more on that in a second). Hardware failure is really a non issue and given that current SSD have error correction, I don't see why one should really expect less than what it is "rated" for. The whole system is really superior by simplicity, no need to spin up/down the platters, no moving heads etc. A lot of the earlier complaints were about the amount of write cycles allowed but what most people didn't realize is that it's rated for that many write cycles to EACH CELL. An efficient controller would spread out the writes across as many cells as possible, virtually eliminating this problem for the majority of peoples use for an SSD.
I'm concerned about the ability to obtain data once one does crash though. So far it's been extremely hard if not right near impossible to recover data off a fried SSD. Most consumers are to ignorant and worry free to back up there data. Although 90% of the time it's not a terribly big deal since they don't have anything extremely important stored on their HDD but when they do, and it crashes, it's usually possible to get the important data back no matter if it was a bad sector/cluster/partition or a hardware failure. Hopefully it will teach some people a lesson.
