    I also remembered: I also changed the SATA cables as well, though that was before the RAM upgrade, and there were still file corruption issues (though lessened) after the SATA cable replacements.

    Probably a coincidence re: the cables. However, no more noticeable issues after the RAM upgrade. Seems the board has some odd memory quirks...

    Retrieved the data from the laptop drive and am now copying that data to the server as Unsorted.

    Will leave a note at that directory regarding the new directory and the existing three: that some of the files have different checksums during transfer in 2021 (what we know so far, anyway).

    I now suspect it was possibly RAM related somehow, as there were no known issues with these disks at that time.

    Seems some of Sis's video collection have different file hashes between her old laptop and the file server.

    This happened before the NAS upgrade in September 2022, so I can rule out my RAID5 setup there. The original copies are still on the old laptop, so I am retrieving those now. But, something's up with the drive installed in the laptop.

    I have since changed the RAM somewhere around April 2023. I have also found out that I can use unbuffered ECC RAM on the ASUS P5N-E SLI board; however, it may not actually use ECC on the system.

    Fixed the directory paths for PureFTPd...

    Going to have to mirror that directory again after that change.

    Um... that broke a LOT of shit.

    Most of it was hardcoded to GNUsocial.

    Database had to be edited, its config had to be edited, some redirects throughout the entire site had to be changed through httpd configs.

    MariaDB database path startup script had to be changed as well.

    I wouldn't be surprised if I missed anything else... like the old PureFTPd setup. I cannot recall how to modify this...

    Finally changing some main paths. Historically, USB drives had a /media directory on Ubuntu; for some reason, hard disks would use this as well. These are finally phased out on this server and will use /mnt as usual.

    Database is migrated to the main webserver drive, the 2TB one... once again. I am going to destroy the nvRAID where the database once resided and create a new RAID1 instead.

    To be fair, the original NAS4Free/XigmaNAS build had no data integrity, either.

    --

    New note on the file server, as written:

    WARNING: THERE IS ZERO FILE INTEGRITY WHEN TRANSFERING [sic] FILES TO THIS FILE SERVER!

    RECOMMENDED PROCEDURE IS TO CHECK FILE HASH BETWEEN SRC/DEST!

    --

    Yes, transferring is misspelled; I only noticed an hour after I wrote the note! http://cwcyrix.nsupdate.info/gnu-social/public/url/34

    Going through the older 2TB storage drives and comparing some of the data with the current NAS data, it is safe to assume the data corruption event started around mid-March 2023 and ended around early April 2023, months after the September 2022 upgrade. May 2023 is when the bad sectors were reallocated.

    Seen this behavior on a suspect hard drive with pending bad sectors in August 2021: on a test Windows XP install using a suspect Seagate 320GB HDD, I copied a large archive to the NAS, then I copied that file to the test system. On the test system, the file was corrupt, even after a few retried copy attempts from the NAS. Of course, on the NAS, it was perfectly fine; hashes matched the one on the laptop but not on the test system. Final attempt was to copy that file to the test system using a USB stick, and that eventually worked.

    Of course, without file system integrity checks, this is the result. I'm just usually very good at catching these so far.

    Long-awaited site backup and HDD upgrade for the server: July 1, 2023.

    The site data is on a single 2TB drive, while the database is on a mirrored 80GB setup, though the 80GB one will have to be done as software RAID and not nvRAID this time.

    I also suspect nvRAID may have a terabyte bug on this old motherboard, so it's better to use software RAID in the long run anyway.

    MariaDB: 10.11.2 -> 10.11.4

    System will be rebooted due to a kernel update on the server.

    apr-util was recompiled due to apr update
    httpd was recompiled due to apr, openssl, curl update
    php was recompiled due to openssl, curl update

    MariaDB will be updated in a few minutes.

    Finally updated the ColoCrossing IP blocklist for the webserver; ballooned the file from ~8K to ~26K! The list had only been last updated in late 2015. At the time they had an IPv6 range as well. That disappeared in 2016.

    It's unfortunate they polluted a lot of IPv4 space over the years.

    Seems the file corruption issue no longer occurs after these reallocation events as well. I'll keep watch; will have to get a replacement HDD if it gets nearly bad enough.

    On another note, my main webserver OS drive (where this very microblogging instance is hosted) actually has 14 reallocated sectors from the original 0 over the years... and the original issue was a stuck UNC that a zero-write cleared (and the bad sector count remained at 0). That was back in October 2011, when the server was migrated to Linux.

    Made a schematic and PCB layout of my custom parallel buffered JTAG (Wiggler) device. From a technical standpoint, the schematic and PCB layout are finished, but I keep cleaning up the PCB layout. So far:

    * PCB routing mistakes regarding nSRST - fixed
    * Potential safety issue between the JTAG header and DC barrel jack - fixed
    * via sizes - changed
    * identification text labeling - now present

    Bad sector count is now 9 from 8 as previously. SMART Device Error count remains at 22, which was there about a month before the first bad sector count (which was at 2).

      That same disk now has 8 bad sectors from 2 known. This may have occurred after Sis sent some files from her old ASUS X555DA laptop to the server. This also makes sense since there were weak sectors in about four areas I know of. Reference: http://cwcyrix.nsupdate.info/gnu-social/public/notice/77

    Tested the JTAG circuit again with the first 74HC244. Confirmed: it does not work. Inserted the second 74HC244 in the circuit, and it works perfectly. The first part is known good.

    I may have run into the one 74HC244 that does not work with TTL spec so far! 😮 But, this is why I have ordered six of them. This is also a reminder to use the recommended 74HCT244 for the buffered JTAG (Wiggler) circuit instead.

    The circuit may work well with 74HC244s, but I implore you, try to source 74HCT244s! You will run into much fewer issues in the long run.

    You may likely run into a rare HC variant that will not work properly with TTL behavior for this circuit (most will work, of course, but still...).

    Status of WholeFlash dump using the practically elusive TJTAG 3.0.2.1 (known as EJTAG Debrick Utility v3.0.2.1 Tornado-MOD) with the unit. Took about 38 minutes to dump the entire flash chip on the system.

    An issue with this version: On Windows XP (on USP4, not sure on official SP3), upon calculating the elapsed time after the dump is finished, it crashes. But hey, at least you receive your file in the process. http://cwcyrix.nsupdate.info/gnu-social/public/url/30
