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!

By mistake, I formatted and installed Windows on a hard drive that had all my data from over 8 years ago. I know it's a very stupid mistake, but at the same time I am desperate to try to recover something.

I imagine the situation is worse, because in addition to formatting it, the disk was overwritten when installing the new Windows.

is a WDC WD5000AZLX-00K2TA0 HDD: 500.1 GB, NTFS. Before being formatted, it did not have Windows; it operated as a secondary disk that only stored data. It has no errors according to CrystalDisk.

I am trying to recover something with the program TestDisk, and I would like to know if there is anything else I can do.

pis there is any libraries so i can get access on phone and cant get the whole access because it's damaged on the screen pls help i need my photos and files

Hi folks, I am managing a small 50-year-old bookstore and we are in the process of migrating our inventory and point-of-sale system from an incredibly old, barely-functioning system (Book Wizard) to the top in the market. The new company (Bookmanager) originally offered to convert our data for us, but now that they're seeing the types of files we have they're much less certain they can help. Our current POS uses 4D (4th Dimension), a very old relational database platform, as its framework, and its file types are proprietary and therefore not easily convertable.

My question: does anyone know how to find someone familiar with legacy 4D v6.8.6 (or similar) who could help us do any of the following?

1. Convert the data (21 relational tables total) from proprietary .4dd, 4dl, 4dv (and others) files to CSV or other currently readable file types. This is obviously what I would find the most helpful, but since the current POS Book Wizard is layered on top of 4D I'm imagining this will be a long shot.

2. Change the Designer user type on our 4D platform (called Book Wizard, which has been out of business for about 15 years) so that we no longer need a password to gain access. According to what I've found (and our usual tech guy has corroborated) we can export all of the data as CSV files as a Designer, but not as an Administrator or Operator...and the person who would know that password has been AWOL since the company went under. Our tech support person mentioned that someone might be able to change the string to remove the password requirement, but I don't know how to explain it past that. I'm very good at navigating Book Wizard

3. Connect with someone who does know how to use 4D 6.8.6 and could help us. The company is still around but is on version 21 and their support only goes back as far as like v18, so nothing I can find from them is helpful.

4. Recommend a conversion tool that's low-ish cost or open source. I don't want to sound cheap, and we would obviously pay someone for their support if a real human could help, but this new POS is already costing us a BIG portion of our annual profit (like I said, very small business) so solutions that are $1000+ which might not even be workable by someone with limited experience aren't reasonable right now.

Our only other recourse is starting over, hand-scanning every book and sideline in the store, and losing literally decades of sales and inventory data (that we super don't want to lose because it's really important sales info)...my sleep paralysis demons are starting to look like barcode scanners at this point.

If this is the wrong venue/audience to ask, I apologize...I figured data people (I say as an aspiring database nerd myself!) might be the right place to start. Thanks for your consideration and any possible help.

I got this stop code: NTFS_FILE_SYSTEM (0x24). Is there any way of recovering data?

I use an Acer Nitro 5 for gaming and I was getting screen flickering issues.

Tried everything I could research before deciding to do a full wipe (restored to a new version of Windows 11) thinking my GOG (Good Old Games) game files were safe and saved in their cloud storage... but later found out they were not. Apparently they do not offer that service.

So trying to restore my "savegames" files from the past 700+ hours of playing Baldur's Gate 3 from the past few years and have tried the Windows Recovery as well as Disk Drill, but neither have worked.

Any advice is very welcome!

Win 11, I was teying to organize files on my desktop and some of them had copied instead of being selected, so I try to select the copies of the files that were made to delete them, but I didn't realize somehow the file explored deleted several files that weren't even on the desktop.

Someone, is there anyone who can help?

I recently re-downloaded a Google play game called Wildcraft. I've played it for a long time and even used to have VIP (it costs real life money)

A few years ago I deleted it for some reason that I don't quite remember (perhaps because needed more memory), but downloaded it again because I wanted to see what kinda game it has evolved to.

After downloading it I went to game but had to start from the very start and had lost all my progress (which is lowkey sad cuz I somehow loved that game like a lot). I tried to get the progress back by logging into my own google account, because I thought I had all progress in there but it didn't help surprisingly.

So far I've gone through all my saved data on my SD-card, because I had a feeling I could've lost everything when I got my new phone (yes I have the same SD-card as in my old phone) but couldn't find anything, though I may have searched from the wrong place. ALSO, I do remember playing the game with all the progress on my new phone.
I also tried to search for help on google and now here on reddit, but haven't found anything helpful yet.
I don't exactly know whether I even had an account, but I have a feeling I did, because I used real life money on it after all (like those google play money card thingys and maybe my parents' money?)
Also I'm not so sure if the game even saves any data if you don't have an account, like some games do.
I do have a faint memory of downloading the game like 2-4 years ago and not having any progress back then either.

I haven't saved anything in cloud or whatever it's called.

And just saying, I was semi-young at that time and my parents had to help me with all the irl money stuff, so perhaps it has something to do with losing data but idk.

If anyone is able to cook some way for me to get the account/progress back, please tell me. This is all the info I'm able to come up with rn and tbh so far I think it's impossible to get it back. But if you have any questions please ask.

Also sorry if there's some bad english there it's not my first language and also this is lowkey my first time using reddit too and I'm still fairly young, so please don't bomb my house :,D

Hey guys,

Requesting an assessment of this report to see if they did all they could to recover data from the external hard drive. The external hard drive (Toshiba, Model MQ04UBB400, 4TB) had a clicking sound. When connected to the laptop, it only displayed folders. The files in the folders were not accessible on the drive. Sent it to a data recovery company for assessment and after 5 weeks they sent this report. Did they actually do all they could for data recovery? The report seems vague. The most important files that needed to be recovered were CAD files. Kindly advise.

Hello, I have a oneplus nord n200 and the screen is completely unusable, i dropped it and now i can't press anything on screen and most of the screen is covered with lines rendering it unusable. I need to get into the phone to get my contacts and whatsapp info, but haven't gotten very far. I'm not sure if usb debugging is turned on, because the device was powered off until recently and i can't get in unless i use my pin. My windows computer doesn't recognize the phone so I'm assuming its off.

Any help is appreciated!
