I have a Seagate SMR drive with 250k/s write speeds (which is even too slow for SMR ). I pulled the drive out of the array. It's out of warranty. Anything I can do?

Have you tried to see how far you can throw it?

 

[Valve1138]

is there a terminal block to midi?

Don't know.

Probably.

Target practice.

Fire up a linux live stick and do an ATA secure erase, which should hopefully revive the write speed.

Then sell it.

In order for parity to work, Unraid 'preclears' the drive by zeroing the whole thing out. So it's been erased. It's just so fucking weird.

No, thats an SMR thing. They can get down to sub 1MB/s if the CMR buffer is full, and that buffer does not clear quick. Like hours to clear it. And then it refills

ATA secure erase command != writing zeros to the drive.

They're sequential writes though. It's my understanding that in that case, it doesn't even need the buffer.

Gotcha. Then I will try it.

APC battery backups suck donkey dick because APC designs their chargers to put +14VDC on the batteries all the fucking time. No trickle charge, no top off. That dries out the batteries, heats them up, and causes them to swell. Oh and they don't give a fuck about bad batteries. Units will pass their 14 day self test no problem with bad batteries. Ugh.

Whats a good battery backup then?

Eaton. They don't do that overcharging non-sense.

 

[Josh]

I'm talking about the SLA battery models, not the newer lithium models. TBH those kind of scare me having all that juice in one easy to explode package.

 

[Valve1138]

Just hook up an AGM car battery to a Tripp Lite inverter/charger.

IDK, I've got a BackUPS 200 that's still on its original battery from 1997, and a SmartUPS 1500 that's on the second round of batteries from the early '00s.

I did have one go tits up from swollen batteries, but that was the same way my cyberpower Costco shitter went out last month.

When was the last time they provided back up power?

last month, when the power went out.

 

[Valve1138]

Mine would fail pretty much every 4th time.

Having a really odd issue. Picked up a couple WD 8TB drives. After running a full test on the drive, and taping the 3.3v pins, I added it to the server. Now when I attempt to boot, the BIOS hangs with a message in the lower corner saying B2.
