User rw Permissions on New Hard Drive




I am running Stretch and after much trial and tribulation, and at times abject horror, I have succeeded in installing a new SSD.

My drive structure is:

comp@AbNormal:~$ lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk
├─sda1   8:1    0 457.9G  0 part /
├─sda2   8:2    0     1K  0 part
└─sda5   8:5    0   7.9G  0 part [SWAP]
sdb      8:16   0   1.8T  0 disk
├─sdb1   8:17   0   1.8T  0 part /sdb1
├─sdb2   8:18   0     1K  0 part
└─sdb5   8:21   0   7.9G  0 part
sdc      8:32   0 465.8G  0 disk
└─sdc1   8:33   0 465.8G  0 part /sdc1
sr0     11:0    1  1024M  0 rom

and my fstab is:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type> <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=ce25f0e1-610d-4030-ab47-129cd47d974e / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=a8f6dc7e-13f1-4495-b68a-27886d386db0 none swap sw 0 0
/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0 0

UUID=900b5f0b-4f3d-4a64-8c91-29aee4c6fd07 /sdb1 ext4 errors=remount-ro 0 1

UUID=1f363165-2c59-4236-850d-36d1e807099e /sdc1 ext4 errors=remount-ro 0 1


Finally, my user group structure is (comp is the  user):

comp cdrom floppy sudo audio dip video plugdev users netdev lpadmin scanner

The problem is how do I set rw permissions on the new SSD?

Googling only leaves me in a high state of mental entropy.

Solutions will be welcome.

Thanks in advance.
