4. to test bad blocks on hard disk on Linux, sudo pv -nb /dev/sda > null or replace /dev/sda with the device identifier of your hard disk.

The errors will print in dmesg (comfortable viewing with command dmesg -TL=always|less -R).

pv may need to be installed as a separate package usually called pv.

It doesn't have a menu entry Menu->System->Hard Disks->"Check bad sectors on your hard disk".

It doesn't even have a menu entry Menu->System->Hard Disks->"Display instructions how to check bad sectors on your hard disk from command line", which I assume would be much easier to implement than the actual menu function, and almost as useful for me.

User experience (UX).

The year 2025, and I casually run into 32-bit limitations of Linux file system tools while trying to verify an old 3TB hard disk drive. Not what I was expecting tonight. #badblocks

🧵 3/n this is bloody embarrassing! 😳

The -p parameter DOES NOT specify the test pattern!

I need to stop #VibeCoding! 🤣
…blame #Mistral small 3 #LLM #AI via #DuckDuckGo duck.ai 😅

Howerver, i've decided to make it extra stressful, by inverting the test pattern.

1 pass = testing inverting 0x55, then another inverting 0xAA - the corrected script in the screenshot.

edit: correct screenshot-final2-corrected2.png 🤣 🍻

🧵 2/n i'm still badblocksing my old HGST Ultrastar 7K6000 4TB (HUS726040ALA610/0F23090).

For some reason, it only produces read errors with the 0xAA test pattern. Reallocated_Sector_Ct increased to 19, after the 2nd pass (13/0/0).

I've started a 5-pack of 0xAA write-read passes - i intent to "burn out" (forcefully reallocate) every last remaining "weak" sector.

This is gonna take the whole week; imma stress this poor puppy until it's not degrading much further.

Oof! Turns out, my offsite backups have never been particularly reliable. I keep 'em on the 10TB HDD from the old mirror now.

I guess, i don't get to resell that old 4TB HDD, then. Meh, i'm not gonna use it myself, and eBay has this "defective / spare parts" setting - 20 bucks incl. shipping.

How to fix:

Bought a new large external disk as data sink for my server at home. The disk is 18TB and after the previous purchase had a hardware problem I wanted to make sure that this one is working. Created a partition, formatted it with ext4 and let's run a badblocks check on it. That failed, badblocks can't handle Big Data.

You know one thing I hate about #SSD #storage?

Testing it with #badblocks will most likely not tell you anything about its health and will degrade it significantly more than #HDD storage.

Are you willing to use refurb/used storage you can't test for proper function though?

I'd be happy to find out I'm wrong and someone has made a program to address this issue... but afaik no such thing has happened yet.
