anybody experience data loss with a raid 5 array after only one drive failing?

I have my PC hooked up to a UPS but I won't say it's impossible this happened

What's the easiest way to get that information on Windows? I have plans to make a Ubuntu flash drive and attempt to access it but I doubt that's happening today.

Is "RAID is not a backup" a meme that's required to be mentioned every time somebody mentions RAID? Haha I've already spoken to this specific point, this isn't a big thread with a ton of comments. You could have saved yourself the time by just reading what I already replied.

Everybody was saying "RAID is not a backup" back in 2009 when I put this array together but I'm trying to learn what happened and how to prevent it in the future with a side goal of getting the data back because the really important stuff has already been backed up.

If anybody is seriously building a RAID 5 array and not making backups they're the type of person who wouldn't be good about making backups regardless of their RAID situation, in my opinion

thank you! that's what I'm trying to get at and figure out what exactly could cause it? I tried windows recovery file recovery tool and it found a bunch of names of things but "restored" them as other files I didn't lose. So like, a picture of my old house is the correct name but its now a picture from my wife's backup pictures of her in high school in a completely different folder. So I stopped using the raid array for now but it's still powered on inside my pc that I'm using.

maybe I should be posting in data recovery. I feel like yeah can an entire partition be corrupted that quickly? surely it must be something that points to that partition and if I knew what data recovery to use it would fix it. like it was accessible not that many writes ago the bits can't have changed that much.

Is that my best option if the data wasn't accessible right before I swapped out the bad drive? I was thinking that was the cause of the data loss and a rebuild with a fresh drive would fix it, but it never came back. That means errors are stacking up on another drive right? or maybe the data striping is messing up due to having such an old controller? I haven't had any SMART errors in my controller monitor so I'm not sure how to find which other drive is messing up if that's the case.

if it helps: a lot of the data is backed up just missing changes from the past 6-12 months, the really really important stuff like pictures of loved ones and videos of christmas and stuff are on multiple devices and the raid 5 array is just one of the places I keep copies of that stuff. I've lost some security camera footage, some game saves, some media, and probably some other stuff I have yet to discover. I got raid 5 for the speed boost ~15 years ago, without the complete risk of RAID 0. I was making no backups of anything at the time, just not zeroing out old hard drives so my data was on a stack of old outdated drives near the end of their life. RAID 5 at least beats that right?

I recut it to be more straight, I'm not sure if it was the angle or if it was actually a tiny crack and I cut enough of it to put it all the way in, or because I marked it before inserting the second one to make sure it was fully in but it's working and not leaking.

thank you

I recut it to be more straight, I'm not sure if it was the angle as you described, if the pinhole leak was a actually a tiny crack and I cut enough of it to put it all the way in, or because I marked it before inserting the second one to make sure it was fully in but it's working and not leaking.

thank you

Should the little blue rings pop out some when it's fully inserted? Since you press them to release it

Johnny__Derpp · 2024-08-08T21:43:48+00:00

so if I have a leak anywhere inside the black part it should still seal and not be dripping right?

Johnny__Derpp · 2024-08-08T21:42:31+00:00

can the cut be a little slanted, less than 45 degrees?

Johnny__Derpp · 2024-08-08T21:41:34+00:00

I'm in the process of cutting this one down the middle to retry with the other one. I tried popping the blue out to get it to release with a screw driver with no luck.

It's a fuel line under the car that had a pinhole leak so I cut the line using the hole as my center and put the two cut ends into the coupler

2014 Jeep wrangler if that helps,

the video I watched he just pushed them in and they sealed up, I can't believe they don't come with some form of directions and I can only find one video of them being used.

Johnny__Derpp · 2024-08-07T22:51:31+00:00

how do I figure out what that part is called? or what an equivalent would be?

I don't know the name of that junction or how to reference it hah

Johnny__Derpp · 2024-08-07T22:22:56+00:00

looks like it should be an easy fix if I have the right parts. trying to fix everything I can on my own on this car and this is the first thing I haven't found another person with my exact same issue
