2cnd drive dissapears - Solved

[moose]

I have 2 internal Hard drives. 240GB Kingston SSD mounted at boot/efi, filesystemroot, and /home.
The second sata drive 1.0TB mounted at /media/gt/mylabel.
I access the second by opening file browser where it is listed under devices as mylabel. Click on that and I have an icon on the desktop for that drive.
I am repeatedly finding that after a period of inactivity this drive disappears from my system. No desktop icon NO entry under Devices and I have to reboot to find it. Both drives are Ext4 format.
Any ideas?

Show your fstab, blkid, and inxi results using a terminal window.

Code: Select all

cat /etc/fstab

Code: Select all

blkid

Code: Select all

inxi -Fxxxzd

Copy/paste those results back to this thread. Use the </> icon above the window and
paste the results between those brackets

Try opening the drive when present and in the caja toolbar choose Bookmarks/Add Bookmark, then 'my label'
will show in Caja Places (left pane)

If you want continuous access to to 'my label' then mount it in fstab--like this:

Make a directory for the mount:

Code: Select all

sudo mkdir /mnt/mylabel

Then copy/paste the following lines to the bottom of /etc/fstab (as root)
be sure to get the entire line.

#mount /dev/sda1 mylabel
UUID=573e9bf2-87c0-46a2-b3a3-335309364b08 /mnt/my label ext4 rw,nosuid,nodev,exec,auto,nouser,async,nofail,noatime 0 2

Then run:

Code: Select all

sudo mount -a

If this returns a command prompt with no errors the drive will be mounted

Thank you all41 for those clear instructions. Thinking it through I'm not really concerned about having continuous access I just want it to be there when I need it so for the time being I've just bookmarked it and kept your instructions for mounting in fstab if i decide to change.
