You have almost the same setup as me. 128 GB SSD 1.5 TB conventional.
Here is how I would do it:
- Leave everything on the conventional drive for the time being.
- Install and partition the ssd using a live distribution usb stick. I wouldn't even touch your old drive here.
- See if everything boots to the new partition okay. You may need to adjust bios settings to make it boot to your new drive.
- set up the mountpoint
You will get something like the following:
/dev/sda1: UUID="0f6e1051-cf9f-4299-b691-76d0d8c532d1" TYPE="ext4"
/dev/sda5: UUID="058b6235-7e74-42ce-96c9-59f6cb0a44f3" TYPE="swap"
/dev/sdb1: UUID="40a50699-a900-4bfe-a9e4-6587c1a83464" TYPE="ext4"
copy the UUID of your secondary drive (mine is sdb1)
paste in uuid line without the quotes and add some fstab goodness:
# /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).
# / was on /dev/sda1 during installation
UUID=0f6e1051-cf9f-4299-b691-76d0d8c532d1 / ext4 errors=remount-ro 0 1
# swap was on /dev/sda5 during installation
UUID=058b6235-7e74-42ce-96c9-59f6cb0a44f3 none swap sw 0 0
# /media/hdd on /dev/sdb1
UUID=40a50699-a900-4bfe-a9e4-6587c1a83464 /media/hdd ext4 defaults 0 2
You may need to change the ext4 to something else if your other drive is formatted differently.
Check to make sure mounts properly
and see if it works.
chown username:username -R /media/home/username
- Link directories you want in home with those on the ssd
These can be done with user permissions, I would suggest you do this with empty directories: For example Pictures
rm -rf Pictures
ln -sf /media/hdd/home/username/Pictures .
Do this for any directory you expect to take too much space, for me it's Pictures, Music, Documents, Videos
- (optional) Carefully clean up the /media/hdd/ directory with root permissions. By carefully I mean do not delete /media/hdd/home !
