• Gigabyte BIOS Upgrade F11b BETA solved a lot of diffuse hardware proble

    From Norm Why@21:1/5 to All on Wed Apr 7 22:46:02 2021
    Hi,

    A 'lot of diffuse hardware problems' is a story too long to recite. I was reluctant to upgrade to a BETA BIOS. When I did I thought I'd bricked the machine. After a nights sleep, I realized the upgrade had reset to defaults
    / PCI monitor rather than PCIe. Now hardware works perfect. However, 500GB Seagate Barracuda says it has 30% life left. The red light that indicates
    drive activity glowed too often.

    The SMART table here can allow looking at individual parameters.

    That means the raw data field in the "Reallocated"
    has gone non-zero. At a guess.

    Thanks Paul,

    Using that tool, '(05) Reallocated Sector Count' was displayed for the 500GB Samsung EVO SSD, but not for the 500 GB Seagate Barracuda SSD. It's
    connected to a different controller, a PCIe (x1) SATAIII card.

    Sorry, I thought that 500GB Seagate Barracuda was a HDD.

    The HDTune tool is too old to display SSD tables properly.

    You were probably using some Toolkit to get that number,
    and maybe the Toolkit has the SMART table in it somewhere.

    My SSD samples here, tend to have rounded numbers,
    like 256GB or 512GB, rather than 250 and 500 values.

    The red glow, means SATA commands are coming in. The drive
    can still be writing, as it rearranges the data, but the
    LED does not light while this is happening. Any LED glows,
    indicate your OS is doing something. You would need to
    probe further, to figure out whether the operations are
    read or write. (Task Manager has I/O columns you can turn
    on for this.)

    The SSD has a processor inside, and it is running for as
    long as the drive has power.

    I did "not much of a test here", on a Win8.1 setup and
    crystaldiskinfo 3.0.4 and the 512KB results are just
    a bit lower than the sequential. There's no huge dive
    like in your 2.018 MB/s result.

    It's not PIO mode, because that would affect read and write.

    It's not error rate, because the other results are
    too good for that. Why would it just ruin the 512KB stuff ?

    I'm sure by now, you've compared your exact model number,
    to graphs already published on the web. And I bet theirs
    don't dip like that.

    You do see the occasional ATTO that is out-of-sorts. Where
    one particular transfer size is not as good as it could be.
    But I don't know if that would be 512KB - it would usually
    be some smaller transfer size.

    See if you can dig up someone elses results for your drive.

    And if it were AHCI versus non-AHCI, I doubt that would do it
    either. There is a good chance a 512KB read or 512KB write,
    would be one "transaction" and multiple packets. Rather than
    being some crazy series of tagged queue requests to do the
    job.

    The cabling is usually pretty good. Only if the cable
    is kinked, with a permanent pinch mark, would I be
    concerned. This sometimes happens when importing cables,
    the cables are wrapped in a bundle, and if some weight
    falls on the bundle, the cable could get crushed.

    There is a counter in SMART for CRC errors on the cable.
    But that counter would be for only one of the two
    directions. On a CRC error, there is likely a retransmit
    request. I don't think it's an ECC, and repaired on the
    spot.

    I can't think why that would be.

    Better class 6 Ethernet cable is twinax. I would think better SATA 3 cable should be twinax. What do you think? I can't find such cable anywhere, just

    7 conductor.

    SATA cabling is nicer electrically than Ethernet. SATA is
    a "brute force" technology, in terms of signal processing,
    and it's "how fast of a sine wave can I run down a coax".

    One thing I like about high speed interconnect, is you
    can scope it, and it can be a "blur" and... it still works.
    That always freaks me out :-) The trick there is clock
    extraction and knowing when to sample the blurry thing.
    The 8B10B code gives a bounds on number of edges per
    symbol time, that ensures there's something to extract
    a clock from.

    There's really no excuse for not being able to
    recover a signal off that SATA cable.

    like 256GB or 512GB, rather than 250 and 500 values.

    The red glow, means SATA commands are coming in. The drive
    can still be writing, as it rearranges the data, but the
    LED does not light while this is happening. Any LED glows,
    indicate your OS is doing something. You would need to
    probe further, to figure out whether the operations are
    read or write. (Task Manager has I/O columns you can turn
    on for this.)

    The SSD has a processor inside, and it is running for as
    long as the drive has power.

    Thanks again Paul,

    I'm still trying to solve some performance issues. Here is:

    Maybe my Startech PCIe SATA controller is to blame.
    I did "not much of a test here", on a Win8.1 setup and
    crystaldiskinfo 3.0.4 and the 512KB results are just
    a bit lower than the sequential. There's no huge dive
    like in your 2.018 MB/s result.

    It's not PIO mode, because that would affect read and write.

    It's not error rate, because the other results are
    too good for that. Why would it just ruin the 512KB stuff ?

    I'm sure by now, you've compared your exact model number,
    to graphs already published on the web. And I bet theirs
    don't dip like that.

    You do see the occasional ATTO that is out-of-sorts. Where
    one particular transfer size is not as good as it could be.
    But I don't know if that would be 512KB - it would usually
    be some smaller transfer size.

    See if you can dig up someone elses results for your drive.

    And if it were AHCI versus non-AHCI, I doubt that would do it
    either. There is a good chance a 512KB read or 512KB write,
    would be one "transaction" and multiple packets. Rather than
    being some crazy series of tagged queue requests to do the
    job.

    The cabling is usually pretty good. Only if the cable
    is kinked, with a permanent pinch mark, would I be
    concerned. This sometimes happens when importing cables,
    the cables are wrapped in a bundle, and if some weight
    falls on the bundle, the cable could get crushed.

    There is a counter in SMART for CRC errors on the cable.
    But that counter would be for only one of the two
    directions. On a CRC error, there is likely a retransmit
    request. I don't think it's an ECC, and repaired on the
    spot.

    I can't think why that would be.

    Thanks for your thoughts. Here is a picture from Wikipedia. "Cross
    section of a SATA 3.0 cable, showing the dual Twinax conductors for the
    differential pairs."
    https://en.wikipedia.org/wiki/Twinaxial_cabling#/media/File:SATA3-TwinAxCable.jpg

    Better class 6 Ethernet cable is twinax. I would think better SATA 3
    cable should be twinax. What do you think? I can't find such cable
    anywhere, just 7 conductor.

    SATA cabling is nicer electrically than Ethernet. SATA is
    a "brute force" technology, in terms of signal processing,
    and it's "how fast of a sine wave can I run down a coax".

    One thing I like about high speed interconnect, is you
    can scope it, and it can be a "blur" and... it still works.
    That always freaks me out :-) The trick there is clock
    extraction and knowing when to sample the blurry thing.
    The 8B10B code gives a bounds on number of edges per
    symbol time, that ensures there's something to extract
    a clock from.

    There's really no excuse for not being able to
    recover a signal off that SATA cable.

    Thanks for the advice. Curiosity: I managed by magic, to get IPv6 working on 'Big Metal'. Now IPv6 addressing works on the other two Windows machines on
    my network. Event Viewer shows far fewer (or zero) events. But no events related to RDP, which I use exclusively. So, IPv6 addressing is essential
    for smooth RDP.

    -maybe.

    I should explain this so I get more advise.

    For many moons, a piece of hardware gave me heartbreak. The heartbreak was
    so bad I was forced to do a clean install. I lost the Gigabyte drivers. In order to connect with to the Internet I used a wireless dongle. Then I was
    able to re-install the Gigabyte Ethernet drivers. Instantly, IPv6 worked through Hercules, HE.net. Once IPv6 works on one machine it works on all machines on the network, that have been set up.
