Questions[hardware-test](ubuntu)

Got one of those Chinese counterfeit USB flash drives. It says it's 128 GB but I know for a fact that it's nowhere near that.

In Windows there are several softwares which help you determine if the capacity the drive is communicating to the computer is true or not. They do that by writing and reading files onto it. A famous software for that is H2testw.

Is there a similar method in Linux? Or any method that would tell me the true capacity of the flash driver?

And after finding out what the true capacity is, how can I change (flash?) the drive to that capacity?

Thanks! ?

I have installed f3 (fight flash fraud) on my Ubuntu 18.04.1 in order to test my USB stick purchases from the command line. My newest Kingston 16GB successfully passed the f3probe test and for practice I want to run f3write and f3read also, but I'm seeing some oddities and have terminated the tests.

The stick is mounted and Files app identifies it as /media/jw/2177-E385 so I have attempted to run the command variously as

1. sudo f3write /media/jw
2. sudo f3write /media/jw/
3. sudo f3write /media/jw/2177-E385.

Which is the mount point that I need for this operation? The partition is located at /dev/sdd1.

I am seeing some 1.h2w, 2.h2w, etc., written into the /media/jw directory in files, but not into 2177-E385.

What concerns me the most is that, when running f3write, the command line shows 908GB free space, the size of my hard drive, not 16GB, the size of my USB stick; I don't want to test the computer's hard drive.

I would appreciate some assistance with the syntax in order to let me know where I'm going wrong.

I have a remote presenter device that connects to my laptop using a usb dongle. It works perfectly for switching slides with Ubuntu's LibreOffice Impress (powerpoint). Is there a way to scan for these commands from my own c/c++ code and do what I like with them?

I want a report on my system health, so that I know that all my hardware components (CPU, memory, disks...) are functioning as expected. It would be easiest to read if the report listed only the problems found (if any). Is there a system tool that does this?

Related notes:

• I know that the disk utility can report SMART results for my disk. I'd like something similar for all my other components.
• Raw diagnostic tools and benchmarks aren't suitable. Diagnostic tools list component details, but not their health. Benchmarks only sometimes highlight health issues. I am only interested in direct health reports.
• I am aware of an equivalent tool that performs this function in Windows (reports if a hardware component is failing), but I've forgotten the name :P I'd basically like an equivalent of this.

I am planning a few videoconferences and I want to check if everything works ok. What is the easiest way to check my Ubuntu installation if it works with Google Hangouts?

The best would be some robot that I can call that plays back my message with some delay. Is there a service like that?

If not, can you suggest any small app that uses webcam & microphone to record a message and play it back.
