That's a good point. As for now, the drive is still uploading folders to cloud storage, although very slowly. I have managed so far to preseve a satisfactory chunk of a much larger chunk.
Got a tip for us?

If these folders are important, why aren't you copying them to another drive?
Could the upload to "cloud storage" be what is slowing things down...?

Sometimes life gets in the way. Not everyone is perfect. And no, uploading to the cloud is completely irrelevant in this case.
Really? Why do you say that? I have a 500MB upload and sometimes my Backblaze uploads go awfully slow, other times they fair well zip along.
Because the copying speed and behaviors of the defective drive has already been observed for a week prior to attempting any sort of cloud uploading.
A Fishrrman prediction:
The OP has been given good advice in this thread, but doesn't seem interested in pursuing much (or any) of it.
As such, I don't see a resolution to his problems any time soon...

These hardware duplicators are different beasts. You dock source Hard drive and target Hard drive into ONE docking station/duplicator. It does not even need computer to work. Docking station itself them copies, block by block source to target. Does not matter which format is on the drive, you get exact copy.
Advantage is, that if the problem is failing hardware AND you can still read it, you get exact copy, as long as duplicator manages to read the data. It avoids talking to drives through USB and all software layers.
Of course, it copies format errors. But if you need to fix format errors, which can be destructive, you may want to make exact copy first and work on that.
Not sure if these duplicators are still sold, they were useful few years ago for hard drives. I do not think you can do same for SSDs so their usefulness is dropping. But they save my data few times when drive started to show hardware issues.
I've mainly been struck by the extreme contrast between the sky-is-falling-imminent-disaster-help-me-Obi-Wan-Kenobi-!!! thread launch and the seeming lack of urgency plus perfunctory rejections of well-meant counsel.

Nice summary. I like it, actually. I'm no stranger to "tech questions" posted online going south immediately, however. This is just another example of all the hostility involved with asking simple questions in an internet environment. The reason for that is the impulse of over 50 percent of readers assuming that you are a "****** listener". I'm not really here to wipe up that mess. Have a good one.
it slow because of bad block and large file. We just hope all your file not corrupt only .
You can get a fairly good diagnostic of the extent of the damage on the drive via this utility which I've found easy to use - DriveDX - https://binaryfruit.com/drivedx
I have about 6 external Hard Drives connected to my iMac, and this utility has been great at doing constant monitoring of all my drives SMART status. Here's an example of a failing drive's SMART status on the tool. If any of those numbers in yellow are high, there's likely significant damage - those numbers will grow over time as you continue to use the drive.
If they are small, likely large amounts of data are still recoverable.

What's happened is that the drive just keeps chugging along very slowly and randomly disconnects every now and then. And then it reappears and keeps going. It's the extreme slowness that ndicated there was something wrong.
However, that was four days ago, and since then I have picked two solutions...
1) Start uploading everything possible to the cloud.
2) Buy another 8TB drive and make a Time Machine backup of the drives.
What has happened since is the Time Machine backup makes a backup of everything, but ignores the 8TB drive. Efforts to copy individual folders of the 8TB drive to the new drive manually are successful.
How to make sure Time Machine backs up external drives
A reader wants to shift his Photos and iTunes libraries to an external drive and ensure they're backed up by Time Machine.

OK, I've only skimmed through this thread, but I don't think anyone has mentioned the opensource utility 'ddrescue'. If you manage to locate someone skilled enough to work on your problem odds are that ddrescue is going to be the tool they reach for first - it's purpose built for situations like yours, where the disk is actively in a state of degrading.
What ddrescue does is first try to read everything it can from the failing drive to a new hard drive, getting those parts of the data that are still able to be read without error. Then it goes back and works on the failing sectors of the hard drive, reading them repeatedly and by approaching from both sides of the track to try and find some way to get the missing data. I've used it very successfully on an obviously failing hard drive, and I was able to recover the data from the entire drive; this was back in the days of HFS+, so your mileage under APFS may be somewhat different.
Here is a decent write-up on ddrescue, which might be enough for you to follow along with. You should know up front that you're going to need a drive that is guaranteed to be large enough, since what ddrescue essentially does is try to replicate the source drive onto the target drive, sector by sector. The risk is that simply buying a second 8TB drive might not be enough - not all 8TB drives have EXACTLY the same number of sectors, and you could find yourself three or four sectors short. A better plan would be to buy a 10TB drive, and know that you won't run into that particular problem.
Good luck, and I hope that you recover your data and set up a backup strategy that has more redundancy. If you have a Mac Pro, as I do, I personally recommend the ZFS file system:
Cheers,
Kurt

My prayer to the tech gods is that everyone reading this thread has (and maintains) a backup strategy with redundancy.
we think before some era before youtuber , some of our demo would be last long but in the end after 10 years, they delete it. So whatever medium backup for business for long term is still tape . ssd will broke , sata will broke .Cloud is next thing for backup but you need to paid it like amazon s3 ,glacier. Icloud still a cheap backup .

On Mac open up /Applications/Utilities/Terminal.app and run fsck because the link shows you how to do on an external!
Some (more recent) versions of MyBook drives encrypt the data, so you wouldn't be able to read the disk in another enclosure (or your Mac Pro) anyway. Even if you used an external block copier, the enclosure probably wouldn't decrypt the data if it detected that the drive had been changed.
