#Pendrive #M2 #nvme #SATA #Szukam obudowy.

Poradźcie porządną (najlepiej #ruggerized) i niedrogą (do 150 PLN) obudowę do dysków różnej długości. Bajery niepotrzebne - przede wszystkim wygoda i odporność.

" First the "SATA" connection has no erase feature and SATA is most often used for disk drives anyway (though some large capacity enterprise HDD have a secure erase button to be used one time before disposal)." *

I can't with some people.

PSA: stop doing dd if=/dev/urandom of=/dev/sdX

use (as root)
hdparm --user-master u --security-erase-enhanced 4HFgWWDzWpRC6 /dev/sdX

hdparm --user-master u --security-erase 4HFgWWDzWpRC6 /dev/sdX

or if you are on a NVME drive
nvme sanitize /dev/nvmeX -a start-crypto-erase

Also please you all make sure that you know what you are talking about before you make a fool out of yourself in a public space

Hier soir à @GEBULL : une séance presque ordinaire d'un groupe d'utilisateurs de #Linux en province…

On a dessoudé un BIOS de laptop HS donné par l'hôpital de la ville d'à côté, reprogrammé cette EEPROM, ressoudé la chose et redémarré la machine ! Pas si compliquée cette réparation

Pour remettre un système d'exploitation sur la machine on a utilisé un nouveau gadget : un stockage NVME dans un adaptateur USB.
En choisissant le bon port USB, la machine démarre plus vite en live que depuis son SSD SATA interne une fois l'installation terminée !! (en un temps record)

Les temps changent…

How in the heck did I manage to fail reads on *metadata* in a 2x3 array :| that's either bizarre amounts of unlucky or my mobo's SATA is shit. Or cables are shit. But smartctl doesn't report anything relevant to I/O failures so it makes me wonder...

Does nobody make a cheap #SATA enclosure with a write-protect switch?

All I could find were forensic write-blockers and duplicators. (Pricey!)

Can you spot the PC mod error? LOL. #geek #projecf #oops #sata

Langsam ist mal gut: Wie schnell Dein Internet sein muss, und WLAN, LAN, USB, ..

Die Bandbreiten scheinen zu stagnieren, beim Internetzugang, bei USB/TB, im (W)LAN, sogar bei einigen PC-Schnittstellen. Im Podcast diskutieren wir die Gründe.

and this is what happens when a #lizard waltz around your #SATA cables :)
here a #repairing #scrub from the #RAID1 #BTRFS array of #HDD .

Follow-up to this note:

At one of the times the current #Armbian #linux kernel didn't crash, but booted on my #RockPro64 I installed #GotoSocial and yes: no more strange error messages running it. The only time I remember that I updated a linux kernel to make an application work.

Preparations to get the production system running with the newer kernel:

• in case of problems I'd need to know my way back to boot the old kernel: u-boot recap and learning
• test suspected problems with the #sata #pcie ctrl beforehand (get a second Pine64 sata ctrl for the test system)

Meanwhile Dragan had patched the device tree and asked to check on a few reboots whether this would make a difference or cause any regressions.

Further down the #RabbitHole the tunnel forks…

I've never been fond of #JMicron #USB bridges! #SATA or #NVMe! (#ASMedia ain't much better?)

It's just a pain in the rear to pull #SMART reports off the drive!

NO, i friggen DO NOT WANT TO fumble around with "-d", and quirks, and shiz!

Tools on friggen #Windows (#CrystalDiskInfo) CAN DO it, so SHOULD smartmontools on #Linux, automatically!

(back in the 480mbps USB 2.0 days - things were BETTER - current #Linux code hasn't caught up)

…or is it #Firmware?

Still looking into building a #computer in the next few months, though I'm waiting for situations to change a little before I commit to anything.

Looking at various #motherboard options, specifically those with a 120 Watt #AMD #AM5 #CPU Socket so I have a good upgrade path. Right now I've gotten it down to a few, but I notice that some of these have multiple #M.2 #SSD slots, and while I do plan to have one of them, I would like the option to have an #HDD, due to the cost-to-storage ratio.

So I'm wondering, is there a way to put a #SATA drive in an #M2 slot? I'm sure someone has made some sort of adapter...

I can go to sleep knowing my Windows XP computer has all the drivers installed!

Hunting down the correct drivers is not always the easiest thing. Finding SATA drivers (you know where you press F6 during the Windows XP install) was a nightmare, but found the correct floppy image eventually!

The nodes themself also came out a lot cleaner, left them in there for months longer than I previously had between cleanings. And it shows well on the last photo where I only cleaned half of the #USB<->#SATA #SSD adapter. This probably means I only have to clean them twice a year. And once the enclosure is fully done, only once a year

This weekend I learned that #NAS systems like #TrueNAS are less limited by network bandwidth than by their #SATA backplanes. I'm only getting sustained SATA speeds of 400 MB/s over a 10 Gbps link when running unquantized #LLM models. That's unusable.

I'd expect a 10-wide RAIDZ2 vdev to provide better read performance than that, but apparently not with my current setup. I'm not yet convinced that an #iXsystems SATA enclosure would do any better.
