Hi,
I have a Western Digital Blue 500GB 7200RPM (WD5000AAKX). After a long story, it had a lot of errors logged in its SMART data. Last time I connected it, its health had decreased to 98% due to those error logs and warnings. Today, I plugged it in and the health was back to 100% but there were error logs. I want to clear the log as the cause for the error has been identified and taken care of and the logs are irrelevant now if not misleading for me. If it has new errors, I might overlook them with a quick look thinking they are just leftover logs of the error that has been solved. Now, I would like to clear the warnings/error logs. Any way I can do that?

Long Story for anyone interested:
I had a desktop, but its motherboard died. Then I got a laptop, I had the 3.5" collecting dust. One day I filled the HDD that came with the laptop and I thought, "Why not use the wd to store some data there?". I had an enclosure for 2.5" at home. I hacked it to work with the 3.5". I modified (basically, just shaved one end to be used as a male connector) a SATA cable to connect the HDD to the enclosures SATA portion and used the power supply of the desktop to power the HDD. After months, the enclosure was destroyed by an accident and I got a new one. It worked sometimes but oftentimes it would disconnect and the disk would turn into a bad disk or raw disk or opening directories in it would make explorer freeze or it would blurt out the error "The directory structure is corrupted and unreadable.". I suspected that the HDD was faulty here as the enclosure would work well when used with a 2.5" I got from my sister's dead laptop. When I opened crystal disk info, it warned me about the disk health. It was yellow. I repaired the bad sectors I found in the disk (I just tried that first because I couldn't think of any other reason it would have a lower health). It went on like this for months until there came a day when I had to transfer a big amount of data and the enclosure kept disconnecting and making the data corrupted and turning the disk into a bad disk. After many tries, it didn't want to work. Then I opened up my laptop and connected the SATA cable to the odds SATA port (it is eSata but the data port is the same). Now, to my surprise, it showed up without any error as a healthy partition, worked without any error, any disconnection. This is where I realized the enclosure was faulty. I'll get a new SATA to USB converter once the lockdown (due to the COVID-19) is over.

Get the right enclosure you'll be fine.

HD Sentinel appears to be warning you about the UDMA CRC Error Count. These errors are related to the SATA interface, not bad sectors.
