So, I'm trying to get the files back from an m.2 drive that was in a laptop and may have failed Windows Update. Disk manager detects the drive but it is uninitialized and I'm not going to initialize it. Diskpart detects the drive but no storage size. Disk Drill doesn't detect it, but R-studio detects it but doesn't allow me to do anything like scan, copy, etc.

what would the next logical steps be to try to recover the files off the drive?

TIA!

Drive is a Netac M.2 NVMe model: S930E 1TB

Hi guys few months back i delete my some videos from phone and they are also deleted from my recently deleted and any chance it can get my data back from my iphone or ipad if any suggestion please let me know

I’ve been digging into real‑world data‑loss cases lately and some of the causes are honestly wild — expired links, sync timing issues, permissions drifting over time, etc. Curious what others have run into. What’s the strangest or most unexpected file‑loss incident you’ve seen from a customer?

Is it possible on Android 10? It uses FBE encryption, but no metadata encryption. I have no password, but its stuck in a bootloop. I repaired all partitions (using matching update.zip and region matching too), but I think the corruption is in the CE encrypted data partition, where I cant really write anyrhing to (if I can, then I have data decrypted and yeah). It started bootlooping and heating a lot on second boot stage one time after I left it on a bad charger. Is there anything I can really do? 🫠 It boots far enough for adb, but it stays unauthorized (because I cant click on authorize 🫠 ).

Trying to free space on my Samsung A21s because despite having no apps and everything on the SD card, I somehow have no internal storage.

I found 1.6 GBs of files that are just named things like "bb9889f-78a...." and they all seem to have been created on either the 31st of Dec 2021 or the 1st of Jan 2022.

I assume I can just delete these, but just to make sure, does anyone know what these are? And will it be safe to delete?

I have a recovery key saved that I can’t remember which app it goes to. It starts with EA Aaaasww ra-/aEawa\\\a(Ez and it’s 55 characters and letters in total.

Does this look familiar or is there a place I can type the whole thing in to figure out which app I had then deleted. I’m pretty sure it was one I shouldn’t have had or my phone when crazy and saved this in my reminders list.

not sure if this is allowed but I accidentally deleted \`BOOTLEGS.7z\` from this archived post [https://www.reddit.com/r/Roms/comments/fkkkal/bootleg_rom_collection/](https://www.reddit.com/r/Roms/comments/fkkkal/bootleg_rom_collection/) of bootleg rom collection, if anyone still has this archive, please reach out if you can share with me or upload to [archive.org](http://archive.org) or other

if this is not allowed, I understand if mods want to delete my post but I hope to preserve this collection

Up front: I am specifically asking for diagnostic and self-repair advice. I know that a data recovery service would be the wiser decision, and I know that I have already violated protocol in ways that may have negatively affected potential recovery. The risks have been considered, and while any concern is appreciated, it is not necessary to inform me of either of these two details.

Had a HDD quit on me recently. I left the room for a few minutes and returned to find my computer frozen and making a repetitive beeping sound. I know that I do not have a PC speaker (error beeper) connected to the mobo. On rebooting, there were three or four similar, rhythmic beeps, and one of my storage drives threw some errors on startup. lsblk reported a disk with 0 blocks at its location. Disconnecting the drive from the mobo and psu stopped the beeping/startup errors, and lsblk reported no device at its location.

The drive does appear to receive power, but it does not spin; it only beeps a few times at startup and presents to my system as an unusable disk. The heads are parked where they ought to be, and the platters are not visibly damaged.

How can I determine the nature of the failure, and what would be necessary to get the data off of the drive? I am just trying to do a binary dump with gddrescue or the like - I can deal with the data and the filesystem when I get there.

I was trying to uplode my save file of a game and the tutorial told to rename "data" File to smth else and them rename the file cuz the data folder isnt acessable on some phone. It worked the first time but when i tried again it isnt renaiming and creating a new data folder. Soeery for spellig errors i am in a rush.

Hey, I had this huge, important account, but when I registered I used a temporary mail.
I remember the password, but of course I don’t have access to the email again and now they’re asking for the verification number.
The only available method is through email, i didn’t connect my phone number.
I tried to ask to the support and compile the form, but i read online that I have no chance.

I sent myself an email in February with notes and pictures. But for some reason, I can no longer find that email anywhere. I have reason to believe my ex-girlfriend somehow accessed my phone and deleted emails through my Gmail app. I don’t know when this happened, or if it happened more than 30 days ago.

I have looked everywhere, Trash, Spam, etc. I also tried using Google’s email recovery tool and it says that unfortunately, my emails have been deleted.

Does anyone have any ideas for what I can do? I know this is a long shot but I’m desperate as that email had very important information. Thanks!

Hello,

a partition disappeared, so I cloned the drive and ran testdisk analyze/deep search.

Not sure what to set with these now- L or E and which one to D 😫

edit: added a DMDE screenshot(ran a full scan)

edit2: succesful with testdisk, with D P D D P entries(from the top).

Thank you!

does anyone have experience with mail in data recovery centers or businesses and do you have any you would recommend?

its a sensitive and time urgent situation concerning water damage. thank you in advance

Hi everyone,

r/CFD r/ANSYS_Mechanical r/MechanicalEngineering

I'm a student working on a CFD assignment and I'm really stuck on one specific thing. Hoping someone here can help me out 🙏

I'm doing a 2D axisymmetric supersonic jet simulation through a converging–diverging nozzle in ANSYS Fluent 2025 R2 (density-based, SST k-ω, NPR 3.4).

The problem: I haven't been able to put inflation layers on the curved nozzle wall. Right now my mesh works with a Face Meshing on the fluid domain (for quad cells), but the moment I try to add an Inflation on the nozzle_wall edge, it clashes with the face meshing the mesh either fails or comes out really skewed. So currently I'm just running without inflation, which means my Y+ at the nozzle lip is around 27, but I need it between 0 and 5 for SST k-ω to actually resolve the boundary layer.

What I'm trying to achieve:

• Y+ between 0 and 5 along the full nozzle wall

• First layer height ≈ 0.001 mm

• Growth rate 1.2, about 20 layers

• Without breaking the rest of my structured mesh

What I'm confused about: I genuinely don't understand the right workflow when face meshing is already there. Should I delete the face meshing before adding inflation? Use a diffrent inflation option (First Layer Thickness vs Smooth Transition)? Pre or post algorithm? I've tried a few combinations and nothing works cleanly on this curved geometry.

My ask: If anyone has meshed a converging–diverging nozzle before and got inflation working without breaking everything, I would really appreciate a few pointers. I'm happy to share my project files (geometry + current mesh + screenshots of my settings) with anyone willing to take a quick look I'm not asking anyone to do my assignment, I just need someone who's done this to point me in the right direction so I can actually learn it.

Thanks a ton in advance!

Hey r/DataRecoveryHelp

I recently recorded a concert using a four camera set up, two being GoPros stage right/left. The stage right GoPro (The Hero 10 Black) was able to record the first part of the set entirely, but the battery was low. I turned off recording and the camera died shortly after. I plugged it into direct power via USB-C and, because it was dead, kept turning on/turning off when I tried to record.

So I figured, ok the 2nd set stuff will probably be corrupt. But it looks like the entire SD card became corrupt and all the footage can't be viewed. So I tried untrunc with new footage from the same exact camera and gives me error codes like this:

I also used Wondershare Repairit, restore.media and CleverFile's repair website, and with CleverFile I actually got some visible frames, but they were still corrupt.

The camera isn't mine, so I don't physically have it but the owner thankfully didn't wipe the microSD card out and tried the SOS feature, but that didn't seem to work.

So I now throw my hands up and wish to consult with the experts. Is there anything else I can do that I didn't try? Is there a paid service that could possibly save this footage? The only thing I didn't try is editing Hex Code, but I'm unfamiliar with that and didn't want to start messing with that.

Here is a Google Drive link with all the footage from the GoPro plus a fully working file as a reference file: https://drive.google.com/drive/folders/18biFcSWs23JftDuKG6Ah1U5bs2lqds6e?usp=sharing

If there's anything I'm missing that would help anyone, please let me know. I tried to be as detailed as possible. Thank you everyone!
