rndp6000-200 saga continues :-(
so my saga continues. I ahve all good drives now, with zero unrecoverable sectors. I was able to make a raid1 array no problems with it. XRAID. I got in another pair of identical drives, verif...
so I think I found the root cause of my issue 🙂
I verified everything was good, from PSU, to the drives, the CPU, to the connections... everything... except for one item, the memory.
I ran a memory test and the error count kept rising and rising took like 15 mins to get to 747 errors...
I pulled one module out and the errors went away.
I replaced them both with one of mine from the shelf and it verified perfection, 0 errors.
so I threw 6 256G drives in, started a factory reset (which never really completed before), and it went through first pass, no issues and really quickly.
I'm initializing the array right now 6x265G drives and it says it should only take an hour and a half... so far things are fully usable and operational even during the array initialization (resynch).
So it's looking good right now but I don't wanna jinx anything 🙂 I'll ahve to dig out 2x4Gig DDR2 ram sticks... I have a full tray of 4G ram, wish I could use those, there are maybe 36 sticks sitting there in the tray gathering dust on the cover ;-(
It is unlikely that you felt a shock from the DC side of the supply. It's more likely on the AC side. But since the chassis is tied to safety ground, not neutral, it's hard to imagine how that's happening (even if the current replacement supply was installed with the AC wires backwards) unless the safety ground is also compromised.

Great news.

There are some 4G sticks that work. The have to be DDR2, non-ECC, unbuffered, and use 2Rx8 banks. Many 4G ram sticks of that era were for servers, so don't meet those criteria. But you can check and see if any do. If they don't say if they are 2Rx8 or 2Rx4, the chip count will often tell you. If here are 16 chips on one side, it's 2Rx4. And you can just try them out -- it won't hurt anything.
BTW, the ram is not dual-channel, so you don't need to install both to check them out and mismatched sticks won't slow anything down.
that tray of memory I have is all ddr3 😞
but I'm sure I have some ddr2 floating around that are 2G or 4G, I have so much surplus stuff over here it's not funny LOL
I may just buy new samsung memory from ebay though, and not take the chance of something that was pulled a decade ago and thrown into a box.
thanks for the help!
