Re: Orico 4 bay HDD dock

Absolutely. Sorry about the somewhat cryptic requests. Is hard to judge level of knowledge on a forum. "fstab" is the file that specifies what filesystems to mount at boot up and can be found in the "/etc? directory and "lsusb" and "lsblk" are commands to find out more information about devices conn...

Re: quest for a nice compact keyboard ?

There is a requirements conflict between "nice" and "compact". Compact keyboards are, generally, not nice and nice keyboards are, generally, not compact. Very true. I am a huge fan of the Logitech K840 series and it definitely ticks the "nice" box. Is also wired. Sadly I doubt it would tick the "co...

Re: quest for a nice compact keyboard ?

Most computer stores here carry compact keyboards for media setups. They would meet your size requirements, but would be wireless. Another area to explore would be small keyboards intended for tablets. I used to have a folding keyboard for a PDA that fits in your size range but they are long discont...

Re: Setting privileges for the script

While the permission allow the execution, and an unprivileged user can run it if /sbin is in your path, it seems that privileges are required to do anything useful with it. Not quite sure what the point is to set it 755.

Re: Cheap sata ↔ usb3 cable to boot from ssd

About half mine are from enclosures and the rest cable type adapters. I'm thinking it's more a known compatibility issue with the Pi4 USB3 than QC. Depending which IC inside there's pretty consistent misbehavior across platforms. I hope it's a fixable firmware problem and not some hardware defect. ...

Re: Orico 4 bay HDD dock

What does your /etc/fstab look like and could you provide the output of lsblk and lsusb with the drives in the caddy (not working) and with them connected separately (working). Could you also provide the model of Pi, exact model of HDD dock, and the the OS you are running

Depends on how you have sudo setup. Do you want convenience or security. Unrestricted sudo without requiring a password, is only slightly better than just running as root. However, it is a real Linux system, you can lock it down as tight as you want. Out of the box, using it as a tinkering and learn...

Re: Cheap sata ↔ usb3 cable to boot from ssd

You may have more success with SSD enclosures as they might have a slightly better USB 3.0 - SATA interfaces in them. They seem to be in the $15-20 range. I suspect the quality control on the really cheap ones ($2-3) is suboptimal.

Thanks for the replies. I definitely am going to look into the SPST switch as I already have my Pi powered via GPIO as it is.

Depending on the setting, it is more demanding on the computer. Yes I know you can run it with the eye candy dialed back, but then what is the point?

Re: shutdown on USB eject

If that is the only use for the Pi (playing videos from USB) it may be worth while setting the SD card with the OS up as read only. That will help protect the SD card. You will still be susceptible to corruption when the SD card is doing low level wear leveling management, but if you are not writing...

For starters I would suggest vetting the forums you read. 16,32,64,128 GB SD cards all work just fine in a Pi 4. It is unlikely the EEPROM just went bad and flashing it should be fairly far down the chain of trouble shooting steps. I would suggest sticking with the Raspberrypi.org forums until you c...

You need to have the windowing system up to have a display to "attach" the graphical program to.

Load Raspbian (get a normal Linux desktop), use VLC to play movies. Could also load Kodi to run when you want it to be a media box.

Movies play fine for me, setup this way on a Pi 4.
