samba shares after reboot

[dm48624]

I am new to this and I have a problem with my samba shared disks after a reboot.
I just installed elemtary OS 8 on my HP Probook and set up a samba file sharer. I am sharing a second hard drive on my laptop and two usb drives in a local network.
Everything was set up and working, then I rebooted and the shared drives were no longer visible. After playing around I found that if I clicked on each shared drive using the file app, then the shared drive would then be visible on the network.
Here is a picture of the lsblk command just after reboot;

After clicking on each shared drive here is how it looked:

This is what my smb.conf file looks like:

[global]

workgroup = WORKGROUP
server string = %h server (Samba, Ubuntu)
server role = standalone server
obey pam restrictions = yes
unix password sync = yes
passwd program = /usr/bin/passwd %u
passwd chat = Enter\snew\s\spassword:* %n\n Retype\snew\s\spassword:* %n\n password\supdated\ssuccessfully .
pam password change = yes
map to guest = bad user

var/lib/samba -s /bin/false %u
################ added by me ############################
usershare allow guests = yes

[anon]
path = "/media/don/Data SSD"
browseable = yes
writeable = yes
read only = no
guest ok = yes

[seadisk]
path = /media/don/SEA_DISK1
read only = no
browsable = yes
writeable = yes
guest ok = yes
directory mask = 0777

[x250]
path = /media/don/External_2501
read only = no
browsable = yes
writeable = yes
guest ok = yes
directory mask = 0777

Any ideas?
