KDE problem mounting Sandisk USB

Asked by peterzay

A Dell Optiplex 7060 with Kubuntu 21.10 has problems mounting a Sandisk Extreme Pro USB 256GB stick.

Sometimes the USB mounts, sometimes it does not. The USB is encrypted with the Ubuntu Disk utility.

It always pops up a small warning window titled Storage Device Health Monitoring. It has a button to Manage.

After clicking Manage, you get a large window titled SMART Status --- Info Center. The sub title is Storage Device Health Monitoring.

It gives a detailed message as follows:

SanDisk Extreme Pro (/dev/sda)

The SMART system of this device is reporting problems. This may be a sign of imminent device failure or data reliability being compromised. Back up your data and replace this drive as soon as possible to avoid losing any data.

Three buttons are offered: Partition Manager, Backup, Ignore

When I first encountered this problem, KDE would mount the USB stick. Subsequent attempts to mount failed: there was no popup offering to mount. The warning window Storage Device Health Monitoring would appear.

A reboot would allow the USB stick to be mounted. The warning window Storage Device Health Monitoring would still appear.

After the reboot, subsequent mounts after the first mount would work. The warning window Storage Device Health Monitoring would still appear.

On another Dell Optiplex 5080 with Ubuntu 20.04, there are no problems at all.

An older Sandisk Extreme Pro 128GB USB stick works fine on Kubuntu and Ubuntu.

Any comments? Is this yet another example of KDE flakiness?

Have you tried checking the device with smartmontools?

If smartctl -t long does not work, you might try smartctl -t short or smartctl --health

In the original question you wrote
"The SMART system of this device is reporting problems. This may be a sign of imminent device failure or data reliability being compromised. Back up your data and replace this drive as soon as possible to avoid losing any data."

Now the output is
"SMART Health Status: OK"

Do you get the SMART warning always when plugging the device in, or only sometimes?
What does smartctl --health tell in a case when you get that warning?

Always.

Sorry, but I have no idea why you first see a warning and later everything is ok.
Maybe somebody else has an idea. I am at my wits' end.

The concept of first and then later is misleading.

Both happen at the same time.

Chronologically, --health (later) was run after USB stick insertion (first).

To me, the answer is simple.

smartmontools on Kubuntu 21.10 is buggy. It is ok on Ubuntu 20.04

Furthermore, the mount popup does not appear upon 2nd and subsequent insertions on Kubuntu 21.10

What output do you receive for the command

sudo smartctl --health /dev/sda

(without the 1 at the end, running the command on the device, not on the partition, see the man pages)

I have been using this Sandisk drive daily (rsync) for weeks on Ubuntu 20.04

There has been no failure to date.

Is this what you would expect for sda vs sda1?

To be honest, I did not expect any output on smartctl ... /dev/sda1 but only for ... /dev/sda

Does
sudo smartctl -t short /dev/sda
work?

Does this "work" in your view?

How can you access the test results?

My brother bought the same model Sandisk USB stick from the same Amazon source.

I tested his device on Ubuntu 20.04 and got the same result as my device on Kubuntu 21.10

I have reached out to Sandisk for their advice.
