How to read SMART parameters from a USB-HDD disk?
Preferably with code examples.
I read that programs like CrystalDiskInfo contain information on each SMART attribute for each manufacturer and that there is no uniform method for reading these parameters.

    in general, .NET is not good friends with hardware, the specifics of the platform. Even in order to find out the banal size of a logical cluster, you have to connect unmanaged DLLs from WinAPI. Your task will most likely require the same. More unfortunately I can’t answer, but you can ask the same question to C ++ or Google specialists to find out the name of the necessary DLL and import parameters, and then adapt it to C #. - rdorn
  • @rdorn: If I understand correctly, C ++ as a language is also not very friendly with "hardware", you need to connect external libraries (for example, from WinAPI). Another thing is that these libraries often have an interface in pure C (as historically it has already), and therefore it is more convenient to connect them to C ++ programs. But this is not a question of language, but a question of the convenience of interop. - VladD
  • @VladD is not so bad, yes, there may not be ready-made functions, but direct access to memory works wonders, even without asm inserts, but it's true that shooting yourself is also easy or even easier =) - rdorn

Of all the good things that I found - only this article (in English) with sample code: http://www.know24.net/blog/C+WMI+HDD+SMART+Information.aspx

Sample code working. Good luck.

  • Thank! The code is working, but, unfortunately, only for HDD. As I understand it, the system (Windows in my case) is just the same as on the other end of the USB cable. MSStorageDriver_FailurePredictData contains only data for internal HDD (IDE or SATA). - badc0de32

Try searching in open source. For example, something similar:

  • Alas, this code raises more questions than answers. - badc0de32
  • Isn't this code for the Linux API? - ߊߚߤߘ
