    Default Dolphin question

    I have just completed a new install on a new computer, and finally got oit working OK.

    I want to transfer all my old files to the new machine. I have a separate hard drive enclosure which plugs into a USB port. The old HDD is installed in the enclosure and plugged in. But it does not appear in Dolphin. The light on it is flashing but nothing else seems to be happening. Could this just be a slow connection or do I need to do something else.

    There is a huge distance between connecting an USB mass-storage device to a system and using it by an end-users desktop application.

    Start a terminal emulator (e.g. konsole) and use
    Code:
    dmesg -w
    It will show you some logging and then stop, waiting for something.
    Connect the USB and see what dmesg reports. That could be errors. In any case it must display somewhere that it sees mass-storage.

    BTW, if on the device is (eventual one or more partitions with) a Linux file system, it could be that you must mount it as root.

    With the device connected, you could also use (as root)
    Code:
    lsblk -f

    With my previous computer I just had to plug in the USB and it was recognised by the file manager. I don't remember having to do anything for this to happen. Running Opensuse Tumbleweed.

    Yes, normally it will also show a pop-up telling the user "in the seat" that something has become available.
    You already reported that these things do not happen. I try to help you in finding out why. But when you do not post what I asked for, the next step becomes difficult.

    So at least, with the device connected (as root):
    Code:
    lsblk -f

    Sorry I didn't realise you wanted me to post the output.

    dmesg after plugging in the USB showed:

    Thanks. I have to go out now, be back later.
    From the dmesg output, I doubt if the device is recognised as being a mass-storage device.

    From the fdisk output, I assume that sda and sdb are both disks you have normally attached, one with the ext4 root file system and the other with the ext4 /home file system.
    When that assumption is correct, the extra device is not visible there, which confirms what dmesg says (or better does not say).

    When I do a similar USB mass-storage connection, I get:
    Code:
    [29844.543462] usb 1-5: new high-speed USB device number 9 using xhci_hcd
    [29844.694696] usb 1-5: New USB device found, idVendor=0ea0, idProduct=1001, bcdDevice= 2.00
    [29844.694701] usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0
    [29844.694704] usb 1-5: Product: Flash Disk      
    [29844.694707] usb 1-5: Manufacturer: USB     
    [29844.696362] usb-storage 1-5:1.0: USB Mass Storage device detected
    [29844.696668] scsi host7: usb-storage 1-5:1.0
    [29845.716784] scsi 7:0:0:0: Direct-Access     NOR      Flash Disk       2.00 PQ: 0 ANSI: 2
    [29845.717344] sd 7:0:0:0: Attached scsi generic sg3 type 0
    [29846.788468] ready
    The message Mass Storage device detected is crucial.When that fails all the mechanisms to create device files, etc. are not triggered.

    Maybe we can get some more information with

    Thanks. Hm, I think the first line is him (or her?). 13fd:161f. Initio Corporation.

    I am a bit at loss here, the more because you say on other system it was recognised as mass torage. Was that also on openSUSE 15.2?

    Did you try several other USB plugins? It could be that USB version is different.

    The HDD is the one that was in the previous computer, and was running Tumbleweed. It worked perfectly well. I just removed it and installed it into the enclosure then plugged it in.

    I have also just tried other USB sticks - two are recognised and show in Dolphin, a third doesn't. The one that doesn't is the USB device which is bootable as an installation source. The HDD is also a bootable device as this is the old HDD from the previous computer; is this maybe why it isn't recognised? A HDD which I had in the enclosure before was also a bootable device but this was recognised by Tumbleweed. I am a bit confused.

    I am having to close just now, I can check again in the morning. Thanks for your help so far.

    Thus, you never had this combination of enclosure with this disk working until now. Thus no prove that you did that inserting in the enclosure correct I am afraid. A lot of uncertainties here.
