I didn't sync to the PTR. I wasn't trying to say the following out loud, cause I'm just "that one guy" I think, and I've mentioned it before, but I only used hydrus to automate downloading from pixiv, and everything else was only imported with a "filename" tag after ripping it with gallery-dl. So a chunk of it doesn't even have URLs to retry. Not that I can eve open hydrus anymore anyway, like I said.

Thank you for the high effort reply. I don't know how late I'm responding to it, but I probably could have responded earlier if I saw it was in reply to me, sorry. Getting the "(You)" for that post expired for me or something.
My "'setup" is just a laptop that can fit two hard drives, and my first reaction to the bad sector was unfortunate. I first posted about it on 4chan's /g/:

But I was running "HD Tune Pro" to check for bad sectors (which I cancelled at maybe 1/4 completion), cause I didn't understand yet (plus no one on 4chan told me in response to any of my posts) that when a sector fails, all that corrupted data is just treated as empty space to Windows (at least Windows 7, which I was still using, and people criticized my still using). I don't know if that's the case for every sort of failure, but I literally saw first hand when I was moving a rare non-hydrus folder on the drive to my second HDD, that (ignoring possibly corrupted data, which I guess wouldn't necessarily have shown) everything in it succeeded besides a single file. The file couldn't be accessed by Windows. But a day later, the file went completely missing. I only came to the conclusion a few days later that that was because it was overwritten from Windows regarding it as empty space. But someone did reply saying that checking for bad sectors via "HD Tune Pro" like I did was literally reading/writing mass amounts of data to literally every part of the drive it could. But I thought that was only possibly exacerbating the failed sector, not overwriting data.
The failing HDD (was also boot drive) was 2TB and encrypted. It took over two days to decrypt it. I couldn't access the veracrypt install folder (viewing its properties showed it as empty), nor could I even consistently read/write data to my HDD, as I mentioned in my first 4chan /g/ post I linked, so I had to install veracrypt portable to my second HDD, and run that to decrypt my boot HDD. Until I realized using the drive was overwriting data, I watched a few streams and youtube videos. I regret that now. I did have the thought that the sheer cost of watching videos was inordinate and should logically be avoided. But I watched maybe two or three hours of video anyway, which obviously is some shit.
After the drive decrypted I created an image of it using "Macrium Reflect" to store on an external hard drive. Unfortunately I first merely cloned the drive to the external, hoping to boot from it, to avoid booting from the dying hard drive again (cause my "setup" only being a laptop meant I had to shut down my PC to replace the second HDD with the replacement HDD, to be able to put data on it). But when I tried booting from the clone on the external hard drive, it didn't even try to do so. So I unfortunately had to boot the dying hard drive. It failed to boot normally. Then it failed to boot in safe mode (both times it froze/stalled indefinitely). Then I tried booting it normally again, and it worked, but I had to cancel the "chkdsk" fix it was going to automatically do within six seconds had I not cancelled.
So I rebooted the dying hard drive, and only then did I make an image of it. I actually cloned it to my replacement HDD first, then I made the image. It's unfortunate the image was the last thing I made. None of the way I approached this was ideal, looking past the fact I lost data due to my having no backups.
Thank you for the patient and comprehensive post, and resources. Cheers. I definitely have so far just given up on archiving. I will try my best to see what can be done to recover the corrupted data on the drive. My boot drive is currently the replacement hard drive I cloned the dying hard drive to, only, I ran "chkdsk" on the replacement before using it, hence the corrupted data showing up as the quantified 23 gigs of empty space in Windows. The dying hard drive hasn't had "chkdsk" done to it, and the image of it hasn't either, nor am I going to fuck with the dying drive nor the original image of it; only copies of it.
I did want to say, to anyone reading this, thinking it would never happen to you, this isn't just losing 23 gigs of a single artist; this is losing 23 gigs across everything you have ever archived. Provided recovery is impossible, you can never trust anything you've formerly archived to be a complete body of work ever again. This isn't the same as no longer feeling safe in your home after having been victim to a break-in; this is literally your entire database changing from complete, to your never being sure, in an instant. Let alone that I can't even boot my hydrus, because I lost shit under the hood, so the only "sorting" I have left is the order in which the images were saved. Literally, if you have anything of value, be arsed enough to sell it to afford a backup. Before buying anything else for yourself, buy a backup for your data. I only hope you will never have to fathom what it feels like to have your formerly flawless-integrity data ruined. I've heard horror stories of losing data before. But on some level, I thought I could afford it happening to me. If it were anything but hydrus, maybe you would have something left. To me, everything I've ever done in hydrus is unusable/ incapable of being observed in any way, in an instant. Backup your data.
