JBURNS489 :
UPDATE: Several months have gone by since I started this post, and I just wanted to update everyone here. The hard drive ended up NOT failing, and after some time the error just went away? It's hard to tell if the pending sectors are still there or not, but crystal disk info is no longer giving me a caution on that drive. Anyone ever heard or seen this type of behavior before? Do you think the drive is safe to trust now?
1) Thanks for taking the time out of your day to do so. And thank you for coming back to your original post instead of creating a new one and confusing a lot of users.
2) It just stopped giving you errors? I wouldn't take that as the drive is now reliable. More likely, the firmware has figured out how to cope with whatever was going wrong. I wouldn't trust this drive as the only storage medium for important information. I'd still keep an active backup of everything on this drive that matters to you, just in case.
3) Crystal Disk Info should not be trusted for all drives. Yes, it's "universal" but for WD drives you want WD software. Their WD Data Lifeguard is specifically designed for their drives. If its tests no longer find any issues, I'd say the drive is at least attempting to function properly. I doubt your platters suddenly fixed themselves, more than likely a software (or firmware) "fix" was automatically applied and has put the issue on the back burner, never to show its ugly head again until all of a sudden the drive completely fails. (just guessing on that last one)
4) Have not seen this before. TBH, storage is not my strong suit. Do I think it's safe to trust now? Not really. There has to still be an issue, it's probably using software to work around it, but that doesn't mean that the drive has physically been repaired.
