Apparently, they (sadly), seem to be suffering from (I'm NOT an expert on this, and could be mistaken) severe autism and/or obsessive/compulsive behavior and/or learning difficulties and/or mental illness and/or the beginnings of dementia.
I concur.  In particular, I detect no malice or intent to derail or annoy anyone, just a deep need to find answers, but difficulty expressing the question and accepting an answer.  I wish I could help.

I even tried to help them understand via a few private messages, but had to stop and block them, because of my own frustration at the communications difficulties.  I could detect myself losing patience, and that does not help.

I do feel compassion, because the root cause is an affliction; but – and I am saying this as someone who has required psychiatric help themselves for recurring depression – classicsamus87 themselves are the only one who can seek help to try and deal with the communications issues, and more importantly, the core issues causing them anxiety and the need to repeat the same questions in an effort to get emotional closure.

Personally, I consider cognitive behavioural therapy the same for your mind, as going to a physiotherapy is after a physical injury.  I don't know if it is applicable to classicsamus87 or if some other form would fit their needs better, but my point is, there is still a lot of misunderstanding what this kind of help is, causing many to reject such help for no good reason.  I myself would have fared much better, if I had sought help a decade earlier than I did; and am still paying the price for that error.  Do not be stupid like I was, please.

he already got countless answer from countless members to his confusing question about his SMART things in countless threads and he keep spitting that shit again and again. i thought repeating things will get a member banned for good, even if he is a real human (usually ads) maybe he expect there is technology to recover bad data and he wont stop spitting shit until he found the non existence answer he expected. he can zip but he doesnt have a butt bone to test and compare data unzipped. somehow he passed the mod's emotional detector. imagine a 5 years old kid asking how to solve third order differential equations but expecting it can be done with simple +-/x. so he keep spitting shit until he find someone can do what he want.

@mechatrommer -- you may want to re-read the posts from MK14 and Nominal Animal, just prior to yours, and the "reassess directives".
How about some empathy?  ???

oh i read Animal's post just before at the "i'm losing patience" phrase... maybe he can retry by replying one or two words simple answers to the "bot" and see if he can fix it. and oh i also read MK14's at the line of "Nintendo DVD nuts" he probably right or wrong, but i feel something terrible has happened anyway somewhere.

How can I prove that I am human? there is no logic to this question I created a register my informations

Registering on a forum doesn't prove anything. We get all manner of automatic spam-bots here (yes, it's a real thing).
*IF* the O.P doesn't mind disclosing their country, I would suggest asking for a photo of the front page of a national or regional newspaper no more than three days old, with their user name written diagonally across it with a marker pen.

Just to be on-topic though, there are zero guarantees that corrupt data will not get burnt to DVD medium, or even copied across HDDs, etc...

A ton of research goes into this topic for data security with mission-critical systems, an error can happen undetected in any number of places, from faulty RAM, or cosmic radiation causing bitflips, or electronic noise, causing undetected errors on the SATA link, just to name a few. Also, don't forget there is also RAM on the HDD itself that can also experience the same issues, it's not just your system RAM at play here.

This is a good read:

Consumer SATA drives are 100 times more likely than Enterprise SAS drives to encounter a read error. If you read 10TB of data from Consumer SATA drives, the probability of encountering a read error approaches 100%

SDC = Silent Data Corruption (this is undetectable without CPU side checksums, etc)
Quote
The SATA channel (and the IB channel) has an SDC of about 10E17. If you transfer data at 0.5 GiB/s you will likely encounter 1.4 SDC's in a year. In the case of faster storage with a transfer rate of 10 GiB/s you are likely to encounter 27.1 SDC's in a year (one every 2 weeks). For very high-speed storage systems that use a SATA channel with a transfer data rate of about 1 TiB/s, you could encounter 2,708 SDC's (one every 3.2 hours).

On the other hand, SAS channels have a SDC rate of about 10E21. Running at a speed of 10 GiB/s you probably won't hit any SDC's in a year. Running at 1 TiB/s you are likely to have 0.3 SDC's in a year.

Technologies like ZFS help with this as all the data is checksummed and scrubbed regularly to find and correct errors that may have happened, but this is only useful if you invest in the required technology to run such an array, such as ECC RAM, and ideally use SAS drives so link errors are detected and corrected.

Data protection is a game of probability, nothing is definite.
