Re: Pi 4B USB Host Boot

well i know the progression was netboot --> usb boot... its been a whole lotta months. hopefully his efforts can be carried over to PI5, would hate to have to wait another year+ for him to figure that one out. I'd stop digging if I were you. You made a fool of yourself, so best to stop. Pi5? really...

Re: USB Hub

Hi - I am trying to add 4 SSD drives to the Pi4 via a USB HUb with its own power source. BUt when using the USB Hub, the Pi will only sometimes boot and even then it will not recognise any device on the 2nd USB connection. Does anyone know what the problem is? A voltage issue? Oh this is a well kno...

Re: Pi 3 to Pi4

great dont want to have to redo what I have done already suggest you use sd card imager and use the image in the pi 4 to start. Never hurts to be careful.

Re: Raspberry Pi4 not recognising external HDD

Have you tried powering up the HDD first, then plugging in the USB cable?

Re: Problems formatting SD Card & loading

I have run into problems formatting sd cards after they have been formatted as Raspian (and Manjaro) boot cards, due to their partitioning scheme. The cards themselves might not be bad, but the partitioning may prevent them from mounting. If you are using a Pi, you can use gnome disk utility, to del...

Re: Pi4, 2GB, and new Buster issue ?

You can probably save your blocked sd cards using gnome disk utilities ( sudo apt install gnome-disk-utility) and then you will see "disks" in accessories. Placing your blocked sd card in an external sd card reader, just delete all the partitions after selecting the CORRECT drive, and then reformati...

Setting up your drive might be easier installing gparted (sudo apt install gparted) as far as installing exfat sudo apt install exfat-fuse sudo apt install exfat-utils to mount an exfat drive, if not done automatically, e.g. drive /dev/sdb1 (or whatever the external drive is) sudo mount -t exfat /de...

Re: Bug with Pi

First, I would try running the board with a fresh install of Raspian. If things go back to normal, then it is a software issue, not hardware. I always have a "virgin" sd card for just such purposes, as I mess up a lot! Before I do anything adventurous I usually do a SD Card Copy first. Aside from my...

Re: SDcard Copier - shrink size of image?

Create your sd card backup, then use gparted to shrink the size of the data partition to as small as your data will allow. Use gnome disk utilties to create an image of that sd card. You can then always use gnome disk utilities to restore that image on another sd card, and the disk utilities will al...

For a quick and simple solution; a cheap USB plug to socket extension cable, with its power wire cut, should solve the voltage back-feed problem. I did try that first.

Re: How to work around power limitations of the USB ports on the Pi4?

Another alternative would be to swap the HDD for an SSD, carefully picking one with low power specs. Depending on the size of the SSD you're looking at way more money that what the Pi is worth! :| I have not found a usb 3 powered hub, with 5V power supply that will work with the Pi 4 and power a us...

Re: How bad/good is cooling on the Raspberry pi 4?

I've pushed a Pi4b below 10°C while in use. just because you can though, doesn't mean it's beneficial. the extra energy required to keep it that cold far outweighs the benefits. it'll run fine at 60°C, get it to 50 if that makes you happy, but ultimately there is no actual need to unless you're hol...
