Backing up my SD - Windows partition not working

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

Then every time after I get:

root@PlexExtra:~# lsblk -o name,fstype,label,size,ro,type,mountpoint,partuuid,uuid

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 :confused:
