    There is a separate power supply to the enclosure.

    @hcvv

    I have been doing some trials this morning with different set-ups. this may get a bit confusing.

    I have two desktop units, the old one I have been using for some time, and the new one I am trying to setup now, call them C1 and C2. I have two HDD for C1 an old one with openSUSE 12.3 and the newer one with Tumbleweed. Both have Windows partitions in addition to Linux, call them H1 and H2. The new one has an SSD and a HDD and Leap 15.2 installed, also with a Windows partition. I also have 4 USB devices, a 2Gb stick, a 16Gb stick (both used for file transfer). a 16Gb stick with the install image for Leap 15.2, and the HDD enclosure. Call them A to D.

    I have tried to use all combinations usng Dolphin file manager:

    C1/H1 can see and open A and B but not C and D
    C1/H2 can see A, B, C and D
    C2 can see and open A, B, not C and D with H1 installed but not D with H2.

    For some time I have been using the Tumbleweed installation and the enclosure with the H1 in as a repository of old files. This has been working well. Now I am updating my computer I firstly need to transfer my files to the new one and then to keep the H1 drive for old files.

    I hope this makes sense. I am wondering if installing Tumbleweed might help as this seems to have been working before. I didn't install Tumbleweed this time as I felt that I don't need a cutting edge distro which has continual updates. I would be interested to hear your comments.

    I tried to internalize all combinations . Indeed strange that some combinations do not work.

    Am I correct that your original report was about the combination: computer C2 (with openSUSE 15.2) and container D with disk H2? Please confirm.

    Computer C1 booted with openSUSE 12.3 (H1) can not access the container (D), but I have no idea what then is in there. In any case, this combination does not tell us very much.

    Computer C1 booted with Tumbleweed (from H2) can access the container (D), but as H2 is used for the system, it can not be in the container at the same time. Thus again that does not tell us much about the usability of container D with disk H2.

    My conclusion, we still have not seen a working combination with H2 inside D. Do you agree with that?
    When that is the case, we still might have a hardware problem in the combination.

    ==========

    BTW I asked to use different USB connections on the system. Did you try that? And, the other way around, are all tests done so far using the same USB connection? For testing you must, when possible, change only one variable per test.

    ===========

    Please note that you apparently did all tests by looking at what Dolphin shows the end-user. While I understand that it was the end-user that oriiginally complained, you as system manager should make your tests on the system level. Eliminate as much layers as possible, and certainly the whole desktop layer with all it's translations into bells and whistles.

    Correct. Perhaps to clarify, my original intention was/is to transfer my previous work files and config files to the new computer.so that I can continue using applications, such as email,etc., with all my existing data. The enclosure would be using H1 which has historic files most of which I don't use but I would like to retain access in case of need.

    I have just found another plug-in drive, a WD My Passport 500Gb, which is recognised by both C1/H2 and C2 so may be the answer to transfer files over. I'm not sure if there may be user ID issues as my old ID was 1001, the new ID is 1000 and the WD drive is 501, other USB drives appear to be user root.

    My conclusion, we still have not seen a working combination with H2 inside D. Do you agree with that?

    Yes. This may not be a problem if I can transfer the files another way.

    I have tried different USB ports but it doesn't seem to make any difference. I am using 1 or 2 of 4 ports on the front of the casing.

    OK, The main issue is solved (but the container/disk combination is suspect).

    For the UIDs.

    To begin with "USB drives" are not root or so. In Linux files have ownership by user:group and to that belong permissions. Does not matter on what Linux file system they are (let alone on which partition, and even more not per device and the way how to connect, USB or PCI or what, as even less to do with it).

    I do not know if you still need H2 in it's old capacity. When not, then my advice would be to use root, cd to the mount point and change the UID and GID on all the files to those of the new owner. Then the new owner will have no problems copying them. That is one way to do it.

    When the old files have the same GID as the new owner, then probably most, if not all, file will be readable by the new user and thus can be copied without problem.
