Mount point does not exist

[Jeremy_Ray]

I'm attempting to mount an external hard drive. In the past I was able to do this by running

sudo mount /dev/sdd1 /media/jeremy/easystore

. Then I knocked my external hard drive off the top of my box, and it hasn't been right since.

Following online instructions, I have added

/dev/sdd1                       /media/jeremy/easystore  ext4   defaults    0 0

to my fstab, saved and rebooted, to no avail. I tried to temporarily create the mount point with

sudo mkdir /media/jeremy/easystore

- which also did not work.

This can't be hard. What am I doing wrong?

I should also add that lsusb does not show the external hard drive unless the USB cable is pulled and plugged back in. Then lsusb shows the hard drive, for a while. After a while, the external hard drive goes to sleep, or does something like that.

And I just reinstalled the OS, and the condition persists.

If you open a terminal and type 'sudo dmesg -w' and plug in the drive you should be able to follow the connect processes.

Are you sure it is /dev/sddx? This can change, depending on what is connected/disconnected at any time.

It is better to use UUIDs which do not change.

But really:

This is the real issue. Something is damaged, or has come loose.

Why doesn't the external hard drive automatically connect on boot? It is plugged into a USB port. I boot up, run lsusb, it does not show. I unplug/replug the cable, run lsusb, now the hard drive is there. But it disconnects after a few minutes, and I have to repeat the process for lsusb to find it again.

In the distant past, when I booted up, the external hard drive was mounted and ready to go. I suppose, for security reasons, we can't have nice things anymore. Now none of my hard drives mount automatically, but at least the two internal drives show up in dolphin and all I have to do to mount them is click on them. Before I reinstalled the OS yesterday, the external didn't show up at all in dolphin until I mounted it manually through konsole. But, at least the external was automatically connecting via USB. I didn't have to pull the USB cable and plug it back in.

Some of the external drives that before 25.10 automatically popped up inviting a mount stopped working for me, and btrfs drives gave problems I've discussed in another thread.

IMO something changed in this behaviour causing trouble for some users.

My workaround has been to add the drives to /etc/fstab, with options noauto,user, mounting by label in case the device changes. F.ex. :

LABEL=othniel /mnt/othniel       btrfs   noatime,noauto,user                0 2
LABEL=noah    /mnt/noah          btrfs   noatime,noauto,user                0 2
LABEL=saul    /mnt/saul          btrfs   noatime,noauto,user                0 2
LABEL=micah   /mnt/micah         btrfs   noatime,noauto,user                0 2

then, I can click on them in dolphin.

Do you see the drives in system settings, disks & cameras, device auto-mount, disconnected devices? Only some of mine do.

The external hard drive does not show up in system settings>Removeable Storage>Removable Devices>Disconnected Devices (or Attached Devices - the internal hard drives are visible in Attached Devices). The external hard drive is also absent from the Digital Camera section. Even if I replug the USB cable, the external hard drive does not appear.

This is how my external hard drive appears in lsusb -

Bus 003 Device 000: ID 1058:2624 Western Digital Technologies, Inc. easystore Portable 5TB (WDBKUZ0050)

What should I enter in fstab?

Wouldn't the usb connectivity issue need to be solved first?

Do they show running sudo blkid? If so, you've got past a USB problem.

In my case failed mounts using the device notifier sometimes caused confusion, with drives becoming stuck until a system restart; even unplugging them and powering them off wouldn't allow a successful mount on being attached again. I learned not to do that.

If the drive has no label you can use the "KDE Partition Manager" or gparted to set one. I find such labels easy to work with, compared to the UUIDs claydoh has suggested.

I'm not sure your problems and mine have the same cause, especially as you're on 24.04. I had no trouble till 25.10.

The internal drives show with blkid.

Here's how lsusb shows the external HD entry -

Bus 003 Device 008: ID 1058:2624 Western Digital Technologies, Inc. easystore Portable 5TB (WDBKUZ0050)

Here's the output of blkid -

That's after replugging the external so lsusb can see it. I don't think the external is in there. Sda1-3 are, I believe, partitions on the flash drive I boot from, and sdb1 and sdc1 are the other two internal hard drives.
