+# Add data disk
+
+I'm trying to add a 1TB SSD drive to banky, connected to the mainboard,
+to use it as a data disk.
+
+I used `fdisk -l` to list the connected disks. The SSD already appeared
+there.
+
+I then partitioned this disk with `fdisk /dev/sda/` (/dev/sda was the
+given name for the disk. The exact name for your case can be checked by
+running `fdisk -l`). The command for partitioning is `n`.
+
+Now it's time for formatting. After some reading, apparently the right
+choice for a linux data disk would to use `ext4`. But bear in mind this
+is not compatible with windows and macos. If you have a disk that would
+like to use across different OS systems, you can pick `fat32`.
+
+To format, pick the partition (you can find it with `lsblk`) and use the 
+mkfs command.
+
+Well that was the theory, because it didn't work for me. I ended up using
+Debian's GUI disk tool. Two clicks and done.
+
+Finally, the disk needs to be mounted. To do so on every boot, you need 
+to add a line like this one to `/etc/fstab`.
+
+```
+UUID=66d23b74-677d-4122-8e67-4bc88ea03b18     /media/data_disk/   auto    rw,user,auto    0    0
+```
+
+Where the UUID should be one for the disk (you can find it out with `blkid`
+or some other of the disk utilities) and the path should exist.

+# Bitcoin core install
+
+Just a few notes to refresh my mind if needed.
+
+I've gone to the bitcoin.org page and downloaded the Linux version
+for bitcoin core 22.0. I followed the instructions there and installing
+was super easy and quick.
+
+My next issue is setting up the config of the daemon so that it stores
+the blockchain in the SSD disk I've set up for that, instead of in my
+small main drive.
+
+After some tinkering, I find how. The default dir where core stores data
+is ~/.bitcoin. When I started the daemon, it started creating all sorts of
+stuff there, including the copy of the blockchain. I completely erased the
+folder, and created a new folder in my target SSD. Then, I used Jameson 
+Lopp's bitcoin core config file generator tool to tweak some settings,
+including the data dir for all data. I placed the conf file in 
+~/.bitcoin/bitcoin.conf and started the bitcoin daemon. Then, the daemon
+started writing into the dir in the SSD I pointed it to through the config
+file. Great success!
+
+Now the blockchain is actively being downloaded. The process is easy to 
+monitor: there is a blocks folder, and each block gets a different file
+within it. So a simple ls allows watching the process live.
