Identical fstab options end up with different permission

Question

I recently attached a SSD to my system, with the old HDD in the DVD drive bay I set up the file mount option in the /etc/fstab file.

The permissions are as follows for SSD:

/dev/sda2   /home/arun/SSD/     auto rw,user,nodev,nofail,x-gvfs-show   0 0

for HDD

/dev/sdb2   /home/arun/HDD/     auto rw,user,nodev,nofail,x-gvfs-show   0 0

The differnce is the HDD do not give me any write permissions unless i am operating as root.

What I tried:

using 'sudo chmod 777 /home//HDD' to change the permissions. command passes correctly but nothing reflects in action(root permission still needed), file permissions do not get a 'w' when i do 'ls -l'
using 'sudo chown /home//HDD' , error: operation not permitted.

I was able to write to this HDD, before I cleaned both my disks and Installed the operating system Ububntu 16.04 LTS.

both the commands were run recursively and non-recursively.

Can This be due to the fact that I installed it in the DVD drive bay? Do I need to change something in the BIOS setting?

Post the output of lsattr /home/arun/HDD. Also, it may be better to create anSSD and HDDdirectory in /mnt and change your /etc/fstab to mount the drives there rather than mounting them in your home directory. — Nasir Riley, Apr 1 '18 at 17:38

run from root this command:

chown -R arun:arun /home/arun/HDD

is that an fat16 or fat32 or exfat filesystem? if yes they can't handle permissions. – D'Arcy Nader Apr 1 '18 at 17:36

NTFS won't take the permissions either. – Nasir Riley Apr 1 '18 at 17:55
yes you are right, you have to set permission on mount. something like this : /dev/sda2 /home/arun/HDD/ auto rw,user,fmask=0022,dmask=0000,nodev,nofail,x-gvfs-show 0 0 – D'Arcy Nader Apr 1 '18 at 18:14
thanks @D'ArcyNader it was a FAT32 partition, now formatted to ext4. problem gone now. – ArunMKumar Apr 24 '18 at 10:01
