Used 2.5" HDDs sold on Aliexpress show misleading data, few hours of use and good health within Crystal Disk Info marked real numbers. My question is: what do they change to show these results? Firmware original, real SMART data, any files on the platters? They (Chinese) remove and modify functions of the original firmware such as head parking and power management.

Wiping (or entering specific data you wish to populate) SMART is simple, a $9 USB/TTL adapter and 3 lines of code typed into a terminal. Faking capacity is just slightly harder, flashing an intentionally corrupted firmware onto the device with fake pointers to the size so they just wrap around and erase what is already there. It's not just China, there are shitty people everywhere!
 
In this process They (Chinese) remove and modify functions of the original firmware such as head parking and power management?
 
Is anyone actually surprised at these charges? Doubt that they are true? That this discovery is only the tip of the iceberg?
 
Buying used hard drives off aliexpress for $4 and you are surprised it is junk? I wouldn't be surprised if these are just rebuilt with non original pcbs and salvaged from disposal places.

Caveat Emptor. If the deal seems to be too good to be true, it very often is!
 
All 2.5" or 3.5" HDDs used and sold on Aliexpress, do they change hours of use, health and other attributes and also modify or remove ou disable functions of the original firmware such as power management and other features?

While there is no hard and fast rule that everyone on AliExptess is a crook, if a deal looks too good to be true it probably is. That said, it is trivially easy to make a 6 year old drive with 5K bad sectors look like it was just taken out of the wrapper. It is just slightly harder to make a 256GB m.2 into something that advertises as a 8TB. You just won’t be able to store more than 256GB, it will tell you the other 7.75TB is there but when you try to access your data it won’t be there!
 
In the "put micro-sd in everything' phase not too long ago, we at my company reached out to several card makers and would get asked "how much storage do you want on the card and how much do you want it to report that it has". Just a standard question of "do you want 4gb cards reporting as 16gb?". I imagine not much has changed in other storage means.

Which country were these crooked manufacturers located in? Asked by all the different card makers?

Shenzhen china. Sorry didn’t realize I hadn’t said it. It was 3 we were asked that by. Finally picked one that was least deceptive. But sad how normal the practice felt.

Yah. I suspect that practice is more common than most people think. Somehow I can't see a manufacturer like Micron or or WD or Samsung doing that sort of customer deception.

Oh for sure. Problem is when you are designing consumer products, you gotta go with the cheap guys :/
 
Do these Aliexpress sellers also modify, remove or disable important functions within the firmware such as power management or other features, or do they use firmware from another HDD model?
 
Do they change or disable some system settings (such as power management) within the firmware and does this affect the parking system?

It's luck (good or bad) as to what settings they enable, the quality (or lack thereof) of the bit flips they make and 100 other variables.

Maybe ask us the same question a couple more times?

Don't buy storage from vendors you don't trust.
 
I know they change SMART to show few hours of use and good health. Changing power functions and power management within the firmware is also easy to change and is it within the SMART changes package?
changing power settings also changes the parking system?

No matter how many times you ask the same question, it's going to be the same answer: nobody knows until you buy the drive and do extensive analysis on it.
