I have noticed that some Seagate shingled disks I have are showing higher than expected error rates. This is what motivated me to adopt PAR2 so that if problems exist with copying the EGTB from one disk to another, any errors can be fixed instantly.

Faults on the shingled disks can be fixed but the disk has to be wiped to do it. Thought I would mention it as the problem can cause games to crash.

An update with some more experiences to share.

So far one Seagate 4TB and one Seagate 8TB drive managed hard disk has crapped out and had to be wiped and returned to service. So far no losses of data suggesting some problems with the disks and sector sparing etc.

I have to use WD drive tool as Seagate's tool does not work. Erasing the disk takes a few hours for an 8TB disk and once wiped clean it can be partitioned and formatted for use again.

NAS users may also want to keep a spare disk on hand to keep an array healthy when a disk craps out.

I also bought a pile of new SATA cables and recently replaced some cables after some problems with a disk disappearing

probably oxidation is hurting SATA cables

When I got my last computer (thankfully before the 'Hoard & Scalp' industry began) I re-used a Ethernet cable that I had known, but forgotten, that should have been replaced (it was holding itself in loosely, broken clip-in tab).

I searched the web for a long time about my intermittent internet connection.

I finally looked at my cable - last instead of first.

I wondered how many on the web forums trying bios updates and what-not had the same problem, some where 'unsolved'.

After puzzling over an intermittent disk issue, I added a new strand of SATA power to the system and then I started swapping SATA cables.

I have one SATA strand for my Corsair H115i PRO RGB water cooler and my Corsair Commander. The commander provides USB for my Corsair HX1000i PSU monitor and the H115i monitor.

I have one more strand for my front USB and my hard disks are handled by a third strand

Turned out that two of my SATA cables were borked so now at least my rig is stable

The only problem I ever had was a bad power supply. Over the last couple of decades all the other parts, major brand names: drives, CPU's, memory sticks, motherboards, all but this one PSU came working fine.

I had bought a veru cheap, on sale, so-called "PSU tester".

I built a 2nd system (back in the reasonable cost AMD Phenom days).

It did not work. My "PSU tester" said my PSU was okay so I returned my motherboard under warranty (paid minor shipping cost).

The MB came back from the major brand manufacturer literally with a small piece of paper obviously hand torn off a larger one with just "Is OK" hand written on it.

Then I did what I should have done 1st: try it with the PSU from my working system. That worked and then replacing the bad PSU I had my 2nd system.

It was the cheap "PSU tester": its LED's lit with very roughly the right voltages but that was not close enough.

I use Corsair power supplies which tend to be invincible, even their RM650 (2019) can put out over 750W (tested) and it still keeps on ticking.

Only ever had one Corsair PSU die, AX860i which is not a cheap model. It evidently was poorly designed and placed the logic board too close to the mounting screws.
