Re: [Dorset] Inconsistent mounting
Not sure why I did not do this earlier, I ran Smartmon test, I can run the two minute test with no problems found, try running the extended test and it always aborts at the 10% mark and when I look at the results there are 8 pre fails in the results. So I am going to bite the bullets and spend my Christmas money on a new USB SSD drive. Thanks you the help and advice Regards Tim H On 07/01/2023 20:44, Tim wrote: On 07/01/2023 12:23, Ralph Corderoy wrote: Hi Tim H, I have an external USB drive Is it spinning rust, which could be slow to spin up, perhaps more so if all power comes from USB?

[Dorset] Inconsistent mounting
Hi I am running Linux Mint 21.1 XFCE desktop on an IBM laptop with a docking station (IBM, specific for laptop model range) I have an external USB drive which I use to backup to and is mounted via a line in fstab at bootup UUID=d90c0c04-8484-453f-9286-ab5e40cfe62f /media/backup ext4 rw,errors=remount-ro 0 0 I use Backintime to do my backups, it is schedule to run daily, one problem is that sometimes it complains that it can not find the snapshot [E] Can't find snapshots folder. If it is on a removable drive, please plug it in. Waiting 30 seconds. If I check my backup drive it says it is mounted and if I open the drive (clicking the icon on the desktop) it will display the folders and start the backup Here are the permission for the mount point mit@NX1:~$ ls -l /media total 16 drwxr-xr-x 4 mit mit 4096 Aug 31 2020 backup drwxr-x---+ 3 root root 4096 Dec 29 07:04 mit drwxr-xr-x 2 mit mit 4096 Jun 20 2021 nas drwxr-xr-x 3 mit mit 4096 Jan 1 21:57 spare I have not been able to find any pattern to how often it will miss the snapshot Any suggestion Tim H -- Next meeting: Online, Jitsi, Tuesday, 2023-02-07 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
