I just discovered about 300 corrupt images on my SSD. What causes this? They were find when copied onto it but over time they become like this. The SSD software says everything is fine.

this one is kind of funny

I had an almost identical problem a few years back with a Western Digital Black hard drive. Drive appeared fine but some files would always end up corrupted when transferred to it. It wasn't the cable or anything. I RMAd the drive and never had any issue with the replacement.

I just put it down to a defect somewhere.

>What causes this?

Probably the SSD.

My knowledge is lacking.

Maybe the SSD is going bad. Back up your data.

fag

HFS+

>What causes this?
Non-checksumming filesystems

File corruption is an *extremely* rare failure mode for an SSD. Usually they're 100% or 0%, not like hard drives which slowly decay over time.

Anyone have the picture? I used to have it but I lost it.

Might also be your RAM going bad, OP. Do you have ECC memory?

That's how I found them. After I found one image like that I compared checksums for every file on that hard drive to my backup.

It's the government trying to destroy all 2D girls to force us to breed with 3DPD so they have more soldiers for the coming war with China. Time to wrap my backups in tin foil.

>that error in the .gif

In the time it took you to post that, I just clicked on the menu, selected “image search -> iqdb” and clicked on the first result

How fucking dependent on others can you be, seriously? Do you also want me to wipe your ass for you?

lots of things could do it, computers are complicated

Bad RAM can do this as error hit during moving and copying, but read errors are temporary as original data is still fine on the dive just read wrong, but write error are permanent as it writes the bad parts. assuming it is is even RAM, but RAM errors tend to hit just about everything not just a group of pictures and most computers have basic tests with manufacturing tools.

I'll check my RAM tonight. The files on my three other SSDs seem to be fine though.

which brand?

The SSD is doing you a favor by wiping out all your weeaboo shit

OCZ Vector. Their supposedly non-shitty one.


Haha Sup Forums just told me this image is corrupt.

Is the sdd old? perhaps youve read/write a lot files to it thus slowly killing it. heat could also be a issue.

>he fell for the ssd meme

stupid comment

you are the cancer of G

lol

Yes, they were corrupt to begin with.

Did you defrag your SSD?
If yes, kek

it's called Shower Room by NaBaBa
you could have been helpful

One year old. Two left on the warranty.

I've written less than 300GB. It's also nice and cool and has never been more than half full.

After I test my ram tonight I'm just going to return it. I mainly used it to browse many large image files quickly, but it's useless now. Everything is backed up anyway so I'm not losing anything,

These look like broken downloads.

A lot of these pictures look like they were written pixel after pixel in order, like how images were downloaded back in the old days. Is that how they are written to disk?

They do but I have the full version of all of them.

>Is the sdd old? perhaps youve read/write a lot files to it thus slowly killing it.
I strongly doubt that. Worst you could do to an SSD is consume all of its P/E cycles after which the SSD would go read-only. And besides, that's virtually impossible to do either way with modern SSDs.

I'm not entirely sure what's up with OP's SSD, maybe the firmware is corrupt or the SSD has a manufacturing defect or something? Bit corruption isn't normal for SSDs

Power failures while writing?

Your SATA controller might be failing, or you could have a RAM issue. I wouldn't actually bet on the SSD failing, that's just not the regular failure mode for an SSD.

>OCZ
you have yourself to blame

Most image formats scan out from the top left to the bottom right.

Keepin mind also that PNG and JPEG are very old formats. The failure modes of something modern like HEVC are usually very different - but even they scan out from the top left to the bottom right (in a zig-zag pattern) on the block level.

If you want to see something else entirely, try corrupting somethign based on wavelets (e.g. JPEG 2000)

>Your SATA controller might be failing

How would I test for that? Just keep transferring a large number of files between drives and look for problems?

plugging the drive into another machine would make more sense.

Those images give me some PTSD remembering old dial-up and those satanic 56k PCI "blue screen friendly" modems on windows 95.

OCZ isnt even bad anymore, in the past 11-12 months they switched to 100% Toshiba nand across all lines

These images are actually pretty rad.

sauce for this and op if possible?

If you get this picture fixed. Post it.

What a waste of a beautiful picture. I totally want a clean copy of it if anyone got it.

can you people at least fucking read the thread and/or JUST GOOGLE GODDAMNIT

there's even a button to do a reverse image search right next to the post, how fucking lazy can you get, seriously?

you goddamn mouthbreathers should all be removed from the face of the earth, waste of resources

Can reverse image even work on a corrupted pic?

didn't for me

Give me an archive of these corrupted images right now.
I need them.

Sorry running memory tests. Posting this from my tablet.

its your browser OP
you saved the picture using a addon or something?
are you using some kind of rare obscure distro?
its in software side

???

1st one worked, 2nd didn't.

I just chased thumbnail to thumbnail for 5 min. in GIS for OP's pic and finally got it at
> danbooru.donmai.us/posts/1867432

not exactly one step, so you're welcome guys

That one was a PNG picture, wasn't it?

I just got promoted at my porn job
Thanks m8

See The original on deviantart is linked on the konachan page and also in this fucking thread

you people, I swear

what menu? why iqdb?
are you a wizard?

>what menu?
First day on Sup Forums? Fucking newfags, just get out

I had some weird bug with a Toshiba external years ago, files in it were fine, but any new files or files moved in the drive would end corrupted. Thankfully copying everything, reformatting and copying back fixed it.

woah there cowboy this is a imageboard

It works when you search for thumb and doesn't when you search for whole picture. Sup Forums's built-in menu uses thumb, 4chanx uses full pic. That's why some couldn't find it.

I swear, how do they manage to breed people so retarded?

WHAT THE FUCK ARE YOU PEOPLE DOING WRONG? I don't get it. It just works here, are you literally retarded?

>WHAT THE FUCK ARE YOU PEOPLE DOING WRONG?
It's really not difficult. There is no need to get so angry.

Here:

>ECC memory
this shit is literally hundreds of dollars for decent RAM sticks

anyone who buys SSDs when they're so goddanm expensive is the cancer of tech consumers

Costs about 20% more than non-ECC for the same speed over here

was not a thumbnail search though

?

im an oldfag but really what "menu" did you click to get an image off the web?

>hmm, it keeps showing lots of images that have dark bottom halves
>I sure wonder whether it wouldn't be better to remove that black bar and try again, since it seems to be confusing the algorithm
>mogrify -trim 1471222805693.png

That wasn't so hard a thought process was it?

Something doesn't sit right with this image as it looks like a figure of some girl not entirely the original. OP, do you have a dead member in your house? Like have you experience any paranormal activity anywhere?

this.
What magic are you using?
I tried both thumbnail and large res.

i have never seen any type of problem like this before, what the fuck

i really dont think its the SSD, it just doesn't make any sense

Well that's quite dissimilar from "use the 4chanx menu"; isn't it?
Nevermind the fact I didn't notice you cropped the picture because of the dumb black background.

Did you just step out of a time machine?

...

I actually did try it with the black bar removed first, however I also trimmed the edges since I figured the extra space was unnecessary

its hit or miss

This has to be a cryptic message or a message from the dead. You remember the thread from /x/ and how Anons were solving the pieces from the capcha to an piece of an corrupted image? I shit my pants over that. Saw it on YouTube. It was mediocre af.

>I can't put 2 and 2 together myself
>If the formula I was taught doesn't work, I have no way of knowing how to respond

How did you manage to pass school? Were you dropped on the head as a child?

so basically the op is just rusing and is just messing up lude anime images to post on here

because that makes more sense

why are you so salty? its like youre really 14 years old.

He has a serious ca seof needing to feel superior to someone in an anonymous image board.

Why are you defending our culture of trained helplessness? How do you expect people to learn anything if you just keep spoonfeeding them?

Because for people to learn someone has to properly teach them first.

wow thats bretty cool who knows it might actually be usefull one day

wokada is a great artist.

2/2

i'm sorry, i'll be needing the original of that

Op please.

Is he still drawing futa, or has he moved on?

only 2 of 200 miku images from him are futa so

And take a look at the non-miku images.

i only want the miku

>IT fags believe checksum can fix corruption.

You need a file system with built in pararchive to fix that shit and no fs does that currently (zfs has a retarded copy mode but that sucks balls).

The checksum doesn't fix corruption, it ensures the file was copied correctly and recopies if it doesn't.

>they're so goddanm expensive
wew lad, time for you to get a job.

I had a shitty ISP modem/router that would corrupt images randomly.

>implying that SSDs dont lose data over time because of the why they store data too
nigga at lest know what your talking about when you point out problem with technology

*way

>btrfs scrub
DESCRIPTION
btrfs scrub is used to scrub a btrfs filesystem, which will read all data and metadata blocks from all disks and verify checksums.
Automatically repair corrupted blocks if there’s a correct copy available.


>zfs scrub
zpool scrub [-s] pool ...

Begins a scrub. The scrub examines all data in the specified pools to verify that it checksums correctly. For replicated (mir‐
ror or raidz) devices, ZFS automatically repairs any damage discovered during the scrub. The "zpool status" command reports the
progress of the scrub and summarizes the results of the scrub upon completion.


checksumming filesystems + redundancy/parity = automatic error correciton

it's not exactly rocket science

>Bit corruption isn't normal for SSDs
It is, they can lose data if they're turned off long enough. My Seagate Pro 600 enterprise class SSDs do so after 3 months according to the datasheet. And all disks suffer from non recoverable read errors.

>It is, they can lose data if they're turned off long enough.
Isn't this just if you're storing them in ridiculously hot conditions for months on end?
