This is a 160 GB rotational drive. Non-enhanced secure erase took about an hour and a half to complete. Enhanced secure erase is taking hours (more than a day) to complete, even though, the estimated completion time is 54 minutes (for both enhanced and non-enhanced erasure). Is this fine or should I be concerned?

Enhanced will do a multiple pass erase and will also include remapped bad sectors. If there are a lot of remapped sectors on the drive, it seem plausible that it could take a long time to complete.

Yeah, it does have a lot of bad sectors, higher than 12000. It's a long story, 3 HDDs of mine suddenly "bricked" while I was using Phoenix OS (one of them apparently survived, an external HDD). It looks like this OS somehow corrupts HDDs' firmware, I say that because CrystalDiskInfo shows this disk's health status as 'Unknown' and I remember it used to show as 'Caution' (the drive had about 56 sectors remapped). The first drive which this OS "bricked" had NONE remapped sectors and suddenly a bunch of sectors got remapped. Some weird thing I noticed aswell is that I have used testdisk app to check for filesystems which was erased, it found a BSD filesystem with 2 TB of storage, the disk's original size is 160 GB

File comment: This is what GSmartControl shows,
realize there are 'cloned' attributes there. Don't mind the high raw values, GSmartControl doesn't shows them properly; CrystalDiskInfo does

The OS is unlikely to have corrupted the drive's firmware. Running a drive that is failing is likely what caused firmware damage. That is, the firmware is stored on the platters and is just as vulnerable to bad sectors as the rest of the drive. When the health status of a drive is showing caution, that is a good time to backup the data and replace the drive and put it to pasture.

Sorry, I haven't informed properly. The external HDD actually was plugged in a laptop (which has none remapped sectors), it was running Phoenix OS aswell. The illness it got was literally the same from these other 2 HDDs, but somehow it survived and still works flawlessly. I never used this external HDD on my desktop computer. And if I recall correctly, this issue happened on kernel version 4.9, I always used to change to the version 4.4 since it was more stable

I read somewhere that by running enhanced secure erase, as it overwrites bad sectors it can actually recover them (if it's not badly damaged) and reset the G-List. Hence why I ran it on this drive. Is this true though?

So, I ended up putting the drive in the freezer four times or so, that didn't solve the issue. But then I thought about using a magnet and it worked! I have no idea why but after magnetizing the drive there are no more read failures. Though, I still think there is something botched in the drive's firmware, S.M.A.R.T. data's attributes got randomized a couple of times after freezing the drive. This is not new though, it used to get randomized very few times even before I froze the drive. But stopped after using a magnet

Great, you got the drive running.
Now, do you want a DR lab to help you get the data soon, right?

Is this a joke ?

Goes without saying using a "magnet" would have destroyed servo and the drive wouldn't work anymore ....

Aslo the OS wouldn't kill the firmware neither the drive. Maybe a bad quality power supply ?
