Re: Simultaneous load on both the SSD and the flashdrive causes the latter to unmount

This hard drive consumes a lot, and therefore requires an external power supply. Among other things, it is extremely important to choose the "right" controller. Many controllers have extremely bad and gluttonous chips, which adds to the problems. What is your USB - NVMe controller? https://www.regar...

Re: Raspberry Pi 4 temperature

CPU temperature is very dependent on the ambient temperature. This is not a linear relationship. So, at a temperature of 20 C, my processor does not heat up above 50 C (taking into account the fact that there are radiators made of copper). But if the temperature is 25-26 and higher, then the process...

Re: Unstable Built-in Wifi on Raspberry Pi 3B+

if such a desperate situation had arisen, then I would roll back. I tormented myself with Buster at the time, and came to the conclusion that there are too many bad solutions in this new Debian OS. Therefore, I rolled back to Jessie (but installed a new kernel) and since then I have no problems. Try...

Re: Brand new Pi - constant problems

It seems to me that these are not Pi problems, these are Chromium problems. My Chromium hangs the OS from time to time and forces me to physically turn off the power of the Pi. I knew that browsers were poorly written programs, so I didn’t really worry. If your other programs work well (for example,...

Re: Raspberry pi not seeing keyboard and mouse. Ssh not working as well.

Your problem is very similar to the problem with the memory card. Try to put another memory card with a new operating system. Sometimes memory cards begin to “break” when some files disappear or programs do not start.

Re: USB3 - NVME drive unreliable

I read a lot about problems with Jmicron chips, so when I decided to connect an external drive to RPI4 (3), I immediately bought the controller ASMedia USB 3.0. It works flawlessly. Yes, judging by the messages on the forums, Jmicron does not work well for many.

If pulseaudio works for you, you should disable this program. It does not work correctly on RPI (RPI engineers wrote about this).

Re: Audio recording (over USB) stuttery on RPi4

Unfortunately, these Buster errors are critical and did not allo...

Most likely problems should be sought: 0. Poor configuration of working with the cache - a slow sd card does not have time to process requests and freezes.
