Problems changing the capacity of an SD Card

Hi,

I am a newbie here, just learning about RiscOS. Having a blast doing so!

I am using RiscOS on a Raspberry Pi 4, and it works fantastically using the default image. I wanted to enlarge the amount of disk seen by the OS so I can transfer some other files over to work on (mp3’s, images, etc) but soon the space left on a 2 Gb card ran out.

I purchased SystemDisc from Piccolo Systems and tried to follow the instructions from there:

I mainly used the following link as a guide:

However, when I reboot I just get a black boot screen with error messages saying:

“Unable to read partition as FAT”

The discs are all new within the last month, and they all work using the standard 2 Gb install, so I don’t think it is a hardware issue.

I would be grateful for any advice how to resolve this.

Hi Grant,
did you have a look at this video as well? https://www.youtube.com/watch?v=jUCkqGsDWUA

Good luck!

Thanks for that Paolo. I will give that a try tomorrow and let you know how it goes.

You can also use USB memory sticks for additional storage. Somewhat simpler than experimenting with SD cards.
