Samba Shares - Access Denied

[not12listen]

my Samba file server has been working flawlessly for months. but, as i keep downloading things, the space fills up.

so, here is what i did:
power off my Linux server (Kubuntu 12.04 LTS)
remove the old 1TB SATA drive
install the new 3TB SATA drive
change the 3TB from MBR to GPT
create the partition (ext4 - whole drive as 1 partition)
put old 1TB SATA drive into external usb enclosure
connect old 1TB SATA drive to Kubuntu server - it is recognized and i can see everything without issue
i copied the 3 folders from the 1TB SATA drive onto the 3TB SATA drive
edited the FSTAB appropriately - adding the 3TB drive and omitting the 1TB drive
edited smb.conf appropriately - altering the location of the shared folders (left all permissions as they were previously)

when i attempt to connect to the shares (which are visible over the network), i get 'access is denied'

i did redo the 'chown' settings - no effect.
i do not know if 'chmod' would have any impact.

anyone else has this sort of issue?

i have fixed it!

what i believe was the issue was resolved with the following:
cd /media/(new hard drive)
sudo chmod 777 (respective folder name)
sudo chown (root user name)group name)

at current, i have full rights and can do everything that i need to!

i hope this helps someone else.
