Add Solid State Hard Drive to Raspberry Pi
USB to SATA hard drive converters have been around for years. When combined with a solid state hard drive we have a fast USB drive for Raspberry Pi. I use this as a backup for my Raspberry Pi.
Here I will take a different approach. Normally one alters /etc/fstab to setup drives. This is very risky and will wreck your system if done wrong. I'll bypass that risk.
I programmed a Python control box to mount/unmount the drive under manual control. The drive will be opened with Thunar or PCmanFM but I use Rox-filer.
Above is my Python control box. It merely does with mouse click what we do from a terminal. I formatted my SSD as FAT32 just like any thumb drive.
This is for Raspberry Pi.
Plug in a USB thumb drive and type the following in terminal:
~ $ sudo mkdir /mnt/sda1
This creates a directory sda1 in /mnt. Now we will map the drive to /mnt/sda1:
~ $ sudo mount /dev/sda1 /mnt/sda1 -rw ; rox-filer /mnt/sdb1
The drive is seen as /dev/sda1 which is mapped into /mnt/sda1. Open /mnt/sda1 and you will see the contents of the drive when rox-filer opens. You will be logged in as root and have read-write privileges. You can use pcmanfm for rox-filer.
Close your file manager and type the following:
~ $ sudo umount /mnt/sda1
Now /mnt/sda1 is an empty directory.
The control box is written in python3 and python3-tk. The complete sample code is open_sda1.py
