I just bought a new laptop with a 512GB SSD and a 1TB HDD. I installed Ubuntu on the SSD (using UEFI) and left the HDD for storage. I had Windows on it, but I deleted it. It had two recovery partitions left and an EFI partition. I assigned most of the left over space as an ext4 partition to use for data, with mountpoint /BHDD. I left 100GB as unallocated in case I decide to revive Windows). I created symbolic links to my Documents, Pictures, Downloads and Music folders in my home directory. However, I can't download files to them - I get an error "Invalid Save permissions". I can create and delete folders or text files on /BHDD.

I am really confused what is wrong.

Update: Interstingly, I can download torrents to the HDD using the default client provided with 16.04 - Transmission

Update2: I installed Google Chrome today just to test whether it will be experiencing the same problem and it is not. I can save files with Chrome wherever I want, so it seems like the problem is to do with Firefox.

Update3: Tried resetting my Firefox profile with mv ~/.mozilla ~/.mozilla.old and using a clean one, however the problem still persists. Also tried reinstalling Firefox by first completely removing it from synaptic and then installing it again with synaptic. The issue is still present.

Update4: I have changed the ownership of /BHDD using chown username:username /BHDD and also set the read/write permissions using sudo chmod 755 /BHDD, but Firefox is still unable to save to this drive.

  • Oh, I just noticed you already mentioned /BHDD. What program gives you the error "Invalid Save permissions" ? – wjandrea Aug 28 '16 at 16:39
  • I get the error when I try to download something from Firefox - that is - after clicking on some download link, I get the error message immediately after pressing 'Save". – ThunderBiggi Aug 28 '16 at 16:56
  • Try the instructions here: Downloading an update, I get this message," You do not have the proper permissions. Choose another save directory". How do I choose another save directory?. I know it's about Windows, but perhaps the same solution will apply here. – wjandrea Aug 28 '16 at 17:09
  • I do get asked where to save it and if I choose to save it on the HDD under /BHDD, I get the the error. Otherwise I can save it wherever I want on my SSD. – ThunderBiggi Aug 28 '16 at 17:40
  • Go to Firefox settings and set the default Downloads location to /BHDD. OR you could use LVM (logical volume management) partitioning. But LVM means you have to redo your entire partitioning again. – ipse lute Aug 30 '16 at 8:57

Ok, I just redid some of the things that I have listed above as not solving the problem and it went away - no idea why. Here is what I redid:

Reinstalled Firefox again through Synaptic - not with the button for reisntallation, but instead removed it completely and then installed it (probably no difference). I left my user files as they were, so it loaded all my extensions and options when I started it for the first time.

Afterwards, I set permissions with sudo chmod 755 /BHDD (which was around the 4th or 5th time of me doing it).

Then finally, I changed the ownership again with chown -R useername:username /BHDD and also chown -hR useername:username /BHDD. (I had also done these a few times).

Next, I opened Firefox and I could download stuff wherever I wanted. Black magic.

I think it help you. I found issue here.

First, make sure that you own the partition. Go to Media then right click on the icon then go to properties. On the middle tab you can see the owner. If it is root then open a terminal by pressing ctrl+alt+T and type the following command:

sudo chown --recursive [yourUserName]:[yourUserName] [pathToPartitionFolder]

without the [] and enter your password when asked. Where [pathToPartitionFolder] is something like /media/7a8s87d8. Try to write a file on the partition.

If you are the owner but it is not writeable then make it writeable by changing the rights on the middle tab of properties.

  • We were probably typing at the same time - as I said, I am not sure what did the trick - but one of the things that I have listed in my answer solved the problem. – ThunderBiggi Aug 31 '16 at 6:49
