Re: Raspian broke after editing just one file?

There are files that only the root/sudo user can modify, because this sort of thing can & does happen if you don't know what you are doing. :D

Good to see you got it back up & running, it's all part of learning how to use Linux. ;)

Re: External HD starting twice on boot.

Rpi3B or RPi3B+?

The 3B needs the OTB to be set to boot from USB, but the 3B+ has it already set, so it might be trying to boot from the USB HDD first.

Re: Issue on using USB 3.0/3.1 drive on Raspberry Pi Desktop

Sounds like the electrics of your USB3 drive are not fully compatible with the USB3 specifications to me.
(Presuming it is self powered, as the RPi only have USB2 sockets.)

Perhaps not innovative but why not create something useful like a mobile internet cafe that you can attach to a bicycle so that it may be used by poor people powering it by just pedalling the bicycle on a stand(?). ;)

Re: What wires are required for plugging in the Raspberry Pi?

Your 5v power supply may not be supplying the correct power for the RPi - recommend using the official power supply. ;)

P.S. HDMI ports on computers are not normally for receiving signals, only for sending.

(If you have the RPi set up for it, you should be able to access it via a cat5 cable.)

Re: 32 gb sd card not working

Try putting a new MBR on that card, then format it - no reason why it won't work if you can get another card to do so.

Another possibility might be to 'image copy' the 4GB card to the 32 GB card.

But probably easier to just put a regular image of Raspbian on it. :)

Re: day to day websurfing and kodi on one distro possible?

In my experience, whilst many devices are recognised, using blue tooth keyboard & mouse on an RPi can be painfully slow.

Re: Forum structure

Databases tend to be flat file or relational, most ordinary people use flat file, whilst businesses use relational, which can be very complex.
If you want to start to get to grips with databases, try using SQLite3, (it should be in the repos). 8-)

Re: "Windows Image Backup" like image backup system for USB HDD installed Raspbian

Sounds like your easiest route would be to install Raspbian to a microSD card or pendrive, add in what you know you want, then use the card copier program, or use dd to make an image file of it.

I know NOOBS is supposed to be easy, but I would 'image write' a downloaded image, (from the Raspberry website), directly to your intended drive.

Re: New Pi b3+ - SD and HDD storage size issue

If you use the card copier in Raspbian, & the hard drive doesn't boot, try writing the Raspbian image file to the hard drive directly.

(I had to do this with one of my hard drives, whilst the other worked OK using the card copier program.)

Re: New Pi b3+ - SD and HDD storage size issue

That version of an Operating System likely has not been updated to run on a RPi3B+

I suggest you install Raspbian, from the official download page, & make yourself familiar with the system.

(You can keep an eye on the Little Black Box website for an updated version, but it may take a while.)

Sorry, I haven't read all this thread, but if you are wanting to access files on a networked drive, I believe it has to be 'exported' from your 'server'. On re reading your above post, if you can access your RPi over the network, perhaps using ssh/sftp might work. (Using a fat32 formatted disk/pendr...

Maybe ctrl + - will shrink it to fit, (can be used multiple times normally) - opposite is ctrl + + to increas the size.
