  1. LaCie120GB external HD freeze system


    Hi,
    when I plug a LaCie 120GB external HD to the USB the system immediately
    freezes...neither Ctrl+alt+del nor anything else works to get the system
    working again; the only way is to shut down the power and then reboot
    again...I googled for this type of problem but there doesn't seem to be any
    of this kind...some user had problem accessing the content but at least the
    device was recognised without crashing the system...


    I tryed the same in Windoz and I get the same result...

    Driver problem? Interrupt problem?...some other type of Hardware problem?...

    Using Mandriva 2008.0 free , kernel 2.6.25...
    thanks in advance for any suggestion...

    Have you tried holding down Alt+Ctrl+Sysrq, and pressing, in order, waiting
    at least a couple of seconds between key presses, RSEIUB?

    Have you tried a different usb port?

    > I tryed the same in Windoz and I get the same result...


    If it's freezing windows as well, this points to a problem either with the
    usb controller, or the device. Could also be a memory or power supply problem,

    You did first attach the powerbrick and make sure the external harddrive
    case has power supplied and lamp/led lit, before you attached the usb
    cable?
    Sometimes, depending upon the usb port and the internally attached usb
    devices (cardreaders and more) they all may fail due to overload, the
    moment your external device is plugged in. Even your keyboard may do so.
    Given the fact, it happens with windows as well, makes the issue look like
    hardware fault.
    Let a "tail -f /var/log/syslog" run on your screen before you plug in the
    LaCie next time, come back with what you see.
    Of course, try the brick on another pc or another device that accepts
    external harddrives.

    ==================================================
    It could indeed be a power supply problem.
    Some time ago I bought a make:NexStar enclosure with USB2.0 interface
    for a 2.5 inch HD . It came with a USB cable with at one end 1 mini USB
    connector for the HD (interface) and at the other end with 2 USB
    connectors for the PC /Laptop , such that power is extracted from 2 base
    machine USB ports since 1 USB port might not be able to supply
    sufficient power. One of those 2 USB connectors is an adaptor enabling
    an additional USB device to be used , instead of the HD occupying 2 base
    machine ports
    FYI ,the NexStar unit has in addition a separate connector for 5 V-DC
    supply . However this supply connection is not needed as long as the
    base machine has at least 2 USB ports


    Don't know the power supply system of the LaCie HD.

    Nope!...
    I borrowed the HD from a friend who did not mentioned that...anyway, I got
    a second cable which ,if I understood correctly is for the power supply and
    then I connected the USB no change...
    Actualy I tryed all possible combination and , no matter what cable I plug
    in first, the system freezes immediately...

    Yes the moment I plug the USB in EVERYTHING freezes...
    My system has USB 2 ports, and the external HD is a USB 3 ...can this be the
    reason?

    Well this is long...the command is given /before/ I plug in the the LaCie of
    course, i stopped it at the point below as i thought that it was not
    influential...
    Thanks for the advices...

    The ones I used are the ones I normally plug in the webcam and the digital

    Yes. /Ctrl+Alt+Del/ will log you out of KDE, and when used in a character
    mode console will reboot the computer.

    >> RSEIUB?

    >
    > Sorry I do not understand the above...is it an acronym for something I
    > should do?...


    Yes. /Ctrl+Alt+PrtSc/ is the key combination you must keep depressed so as
    to be able to use the /SysRq/ sequence, and that sequence is /RSEIUB./

    By holding down the /Control,/ /Alt/ and /PrtSc-SysRq/ keys together, you
    can enter System Requests to the kernel directly. Each of those is
    accessed by pressing a single key, and with the given sequence, the meaning
    is as follows...:

    - R : puts your keyboard in "unRaw" mode
    - S : emergency Sync of the buffers to all mounted filesystems
    - E : sends a "tErminate" signal to all running processes in the
    runlevel except for /init/
    - I : sends a "kIll" signal to all running processes in the runlevel
    - U : emergency read-only remount of all physical filesystems
    - B : same as a hardware reset

    The mnemonic for remembering the proper sequence is the silly sentence...

    "Raising Skinny Elephants Is Utterly Boring"

    So you must hold /Ctrl,/ /Alt/ and /SysRq-PrtSc/ down together and then
    press the first character of each word in the above sentence, and in that
    order. Even if there is no visual feedback - e.g. because the screen is
    locked - you should pay attention as to whether the keypresses have any
    effect by listening to your disk heads and watching the hard disk light.
    Don't execute the sequence too fast. Every keypress must trigger an
    appropriate reaction.

    .... While the other combination is used for System Requests, as I've

    Your own mistake here made me goof up... :-) The /Control/ key is *not*
    needed for System Requests. One only needs to hold down both the /Alt/
    and /PrtSc-SysRq/ keys and then while holding them down press any of the
    following:

    Again, the /Ctrl/ key is not needed. My mistake! :-)

    UHM. USB3 isn't out yet. There are only 1(.1) and 2.0 AFAIK.

    Unfortunately, there is nothing related to the crash.
    I meant, you should keep the konsole open monitoring the output, while
    attaching the (faulty?) usb drive. Of course you'd have to write down the
    last lines by hand, as they rarely would make the way to the disk when the
    whole subsystem hangs ... but these lines would be truly informative.

    I relied on what the owner of the external told me...but you are right, I
    now checked the Hd and says USB2...

    I did as you said and kept the console open when I plugged in the the USB
    but no messages and again a total freeze...
    and now I give up, I cannot have my system freeze all the time and then shut
    the power off as the only solution...the computer did not react a wink even
    with the Alt RSEIUB suggested by Aragorn and David...I guess that the LaCie
    HD just does not work here, and it is the only type with which I had this
    problem...
    Thanks for your patiente and answers...

    Heh, heh. Luckily, that's a key combo I rarely use. Holding down the ctrl
    key, as well, doesn't seem to hurt. I expect I'll remember now, though, that
    ctrl is not required.

    Yeah, I got thrown off course by Santo's own mentioning of the /Control/ key
    in that sentence. ;-)

    Also, it might be worth mentioning - although I suspect you and other more
    experienced users already know this - holding down the /Control/ key when
    using the /Ctl+Alt+F[something]/ is indeed needed when switching *from* an
    X11 session *to* a character mode login console or to another X11 session
    running on another virtual console, but when switching from a character
    mode login console *to* an X11 session, it is not.

    In fact, one can even use /Alt+left_arrow/ or /Alt+right_arrow/ to switch
    between character mode login consoles and even for switching to an X11
    session if that happens to be running in the next virtual console, but of
    course once you've arrived at an X11 session, you do need to use
    the /Ctrl+Alt+F[something]/ to switch on again. In my set-up here - and
    I've forgotten whether this was a default setting or whether I've changed
    it to this myself - using /Ctrl+Alt+left_arrow/ or /Ctrl+Alt+right_arrow/
    switched to the previous or next virtual desktop.

    One thing I did notice during my initial Gentoo test install was that Gentoo
    is obviously set up to switch between character mode login consoles by
    simply pressing the Windows key on your keyboard, without pressing any
    other keys. It then simply cycles the available character mode login
    consoles. Of course, this would most likely not apply to an X11
    environment. ;-)

    Either way, I guess you'd have to experiment with pressing the Windows key
    of your keyboard in a character mode login console on Mandriva yourselves,
    because I don't know whether the latest Mandriva releases are set up that
    way as well. My older Mandrake 10.0 here isn't, for one.

    See, this is one of those things that GUI-only GNU/Linux users won't know
    about, but the concept of using virtual consoles in GNU/Linux is just one
    of those things that simply make you love this operating system, and then
    I'm not even getting started on the differences between /bash/ -
    or /tcsh,/ /zsh/ or /pdksh/ for those who prefer those - and the Windows
    DOS-emulating commandline with its limited functionality and its limited
    set of commands. :-)

    Long live the Gnu and the Penguin, that's what I say... ;-)
