I’ve just tried again but now I get a different result:
root@PlexExtra:~# lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uu id
NAME FSTYPE LABEL SIZE RO TYPE MOUNTPOINT PARTUUID UUID
sda 119.1G 0 disk
mmcblk0
│ 119.1G 0 disk
├─mmcblk0p1
│ vfat 128M 0 part /boot d5900763-01 447A-61ED
└─mmcblk0p2
ext4 119G 0 part / d5900763-02 0c775223-1871-4eeb-8d39-1eb6a931dc4f
root@PlexExtra:~#
Then every time after I get:
root@PlexExtra:~# lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid
NAME FSTYPE LABEL SIZE RO TYPE MOUNTPOINT PARTUUID UUID
sda 119.1G 0 disk
mmcblk0 119.1G 0 disk
├─mmcblk0p1 vfat 128M 0 part /boot d5900763-01 447A-61ED
└─mmcblk0p2 ext4 119G 0 part / d5900763-02 0c775223-1871-4eeb-8d39-1eb6a931dc4f
When I reboot I get the first result the first time then the second result until I reboot again.
If I do the check on sda I get
root@PlexExtra:~# dosfsck /dev/sda
fsck.fat 4.2 (2021-01-31)
Read 512 bytes at 0:Input/output error
Putting the sd back in my pi everything boots up and works as normal still
