RPI4 - Problems with USB3 HDD - Crash after a few hours

1st Official Post

    Hello,

    I am still setting up my Raspberry 4 with LibreELEC 9.2.1

    Every few hours my system is crashing. This only happens with a connected USB3 HDD. With a connected USB2 HDD everything works fine.

    I have tested with my RPi 4 (2GB) and my RPi 4 (4GB). Both are the same result.

    dmesg generates the following output:

    If i than try to read Data from the Drive i get

    Code
    [18066.706030] usb 2-2: reset SuperSpeed Gen 1 USB device number 2 using xhci_hcd
[18066.724117] sd 0:0:0:0: [sda] tag#0 UNKNOWN(0x2003) Result: hostbyte=0x03 driverbyte=0x00
[18066.724128] sd 0:0:0:0: [sda] tag#0 CDB: opcode=0x28 28 00 3a 38 57 80 00 00 08 00
[18066.724135] print_req_error: I/O error, dev sda, sector 976770944

    Sometimes (but not always) i can reboot with the command:

    Code
    reboot -f

    I have found following tips that did not solve this problem:

    - Use another power adaptor. This problem is also when i use a powered USB2.0 hub.

    - From ( STICKY: If you have a Raspberry Pi 4 and are getting bad speeds transferring data to/from USB3.0 SSDs, read this - Raspberry Pi Forums)

    Add to cmdline.txt:

    Code
    usb-storage.quirks=XXXX:XXXX:u

    Add to config.txt

    Code
    force_turbo=1
over_voltage=2

    But this problem still exists.

    What can i do to solve this?

    The HDD works on my PI3 without problems. Or is the HDD about to die?

    I'd leave out the overclocking and start without it to get some sort of 'baseline' which "should" work.

    And maybe your USB3.0 controller is a bit too quirky.

    It's hard to tell anything without full dmesg. Could be undervoltage (that'd be logged in dmesg), could be the USB HDD adapter (model/vendor would be in dmesg) or something else.

    Thanks for dmesg, couldn't spot anything unusual except for the warnings you posted.

    Can you check if the VIA USB firmware is up to date (in LibreELEC Settings->Update)?

    It could be that your drive is acting up or dying, hard to tell though - haven't seen your specific issues yet and 2 WD drives (3.5" MyBook and 2.5" MyPassport) are working fine here on RPi4/USB3.

    so long,

    Hello,

    many thanks!
    There are Updates available i will test them:

    Bootloader EEPROM from 2019-07-15 to 2019-09-10

    VIA USB3 from 00013701 to 000137ad

    I think i have found my problem. I have a script running to monitor the system. There is this query included:

    Code
    hdparm -C /dev/sda

    if i disable this, everything works for hours without problems.

    It seems there is a bug with this query.

    Many thanks for the help!
