19 March 2019 introduction

My computer has 2 drives, I use the 2nd for file storage and the 1st for the OS. Been unable to access the 2nd's contents. I get the following message clicking on it:

Error creating mount point `/media/jay/HP_PAVILION Adjacent Reserve 1_2': Read-only file system

I read the 2011 suggestion Lekensteyn made at How to make read-only file system writable? and tried the following command on LXTerminal:

sudo mount -o remount,rw '/media/jay/HP_PAVILION Adjacent Reserve 1_2'

I got the following response:

[sudo] password for jay: 
mount: /media/jay/HP_PAVILION Adjacent Reserve 1_2: mount point does not exist.

When I try to access the shortcuts I made to folders that were on the drive, I get messages like:

The specified directory '/media/jay/HP_PAVILION Adjacent Reserve 1_2/!uTorrent completed downloads' is not valid

This is also giving me an 'error' when trying to magnet-torrent (via Transmission) the latest (18.10) version of Lubuntu which I'd like to try out.

Even downloading it normally gives an error:

could not be saved, because the disk, folder, or file is write-protected. Write-enable the disk and try again, or try saving in a different location.

My comp also in past has spontaneously blackscreened (audio kept going) after around 20 minutes of running.

This may be related to past problems of blackscreenining on boot-up unless I do a "Resume Normal Boot" after AORMing (Advanced Options : Recover Mode) on startup.

I asked about this back in September How do I fix a frozen black screen on Lubuntu startup?

However I get so frustrated by it that I abandon the comp for months when the problems seem to accrue... I'd really like to be able to understand why it black-screened and if this is connected to why my 2nd drive was put into write-protect, and if it's connected to the black screen on startup.

Would I be better served trying out another Ubuntu OS? I don't know which is compatible with really old graphics hardware.

reply 1 to guiverc:

I read a February 2017 reply by nnema at Root file system requires manual fsck

This appears to imply that I would do a reboot, and then when I do an AORM as I usually do, instead of cancelling the Advanced Options Recovery Mode that I should select "root access" and then enter one of the following lines:

sudo fsck -f /
sudo fsck -f /dev/sda1

Any commendations which would be better? Either way I must type 'reboot' after.

Soren A asked why not try using the terminal, so I tried this with the 1st and got following readout. I typed "y" whenever it asked "fix?" because that seemed like the right thing to do...

I assume since it says "reboot system" that I should do a restart now. I will try this now and if I can still use my computer, update with whether or not the drive is accessible.

reply 2 to Nonny Moose:

looked up How can I check the SMART status of a SSD or HDD on current versions of Ubuntu 14.04 through 18.10? which recommends getting "Disks Utility" to do this. I did not see it under "System Tools" so AFAIK it doesn't come with Lubuntu by default.

I opened Synaptic Package Manager to try and install it and as soon as I entered my admin password I got the following error message:

An error occurred
The following details are provided.

E: Couldn't create temporary file to work with /var/lib/apt/lists/ca.archive.ubuntu.com_ubuntu_dists_bionic_InRelease - mkstemp (30: Read-only file system)
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.

W: Not using locking for read only lock file /var/lib/dpkg/lock-frontend
W: Not using locking for read only lock file /var/lib/dpkg/lock

Do you know if there is any default software that comes with Lubuntu that I could use to check SMART status? I don't think I will be able to install anything new until I fix this.

update 3 (March 20) FSCK fixed it, thanks guys!

  • The mount error is telling you /media/jay/HP_PAVILION Adjacent Reserve 1_2 does not exist; it must already exist (as a directory) in order for you to mount a device to it. A common reason for a file-system to be read-only is because it has errors, and needs fsck (file system check) – guiverc Mar 20 '19 at 02:15
  • Sounds like the problem is that the file system to which the 2nd drive is mounted (i.e. your OS drive) is read-only. You might want to run a SMART check. – Nonny Moose Mar 20 '19 at 02:15
  • Thanks you two for the fast replies! I have edited in responses above to your comments. I am doing a reboot now to see if the fsck fixes accompished access to the Synaptic Package Manager so I can install the Disks Utility which NM recommended. – VistaRefugee Mar 20 '19 at 02:44
  • okay I rebooted and can access my drive now, fsck suggestions seem to have worked – VistaRefugee Mar 20 '19 at 05:50
