Recover the Hard Drive Corrupted by Mounty Mac Software

If Mounty NTFS made your files vanish on a Mac, you’re probably dealing with file system errors, not instant permanent loss. I’ve been there. This fix is for anyone whose NTFS drive stopped showing files after using Mounty. You’ll learn the quickest recovery step that often works, when it won’t, and what I’d do next so you don’t make the damage worse.

One evening, after a long day, I plugged in an old NTFS drive to my Mac and thought, fine, I’ll save a few bucks and use Mounty instead of paid software. Bad idea. The drive mounted, I moved things around, and then some of my files just stopped showing up. Cold little panic in the stomach. Proper awful.

The annoying part is this usually looks worse than it is. In many cases, the files are still on the drive, but the file system metadata is damaged, so the drive can’t point to them properly anymore. That means your first job is simple. Don’t write anything new to the disk.

What probably happened

Mounty has been a popular workaround for writing to NTFS drives on macOS, but these NTFS-on-Mac hacks have always been a bit shaky. Apple doesn’t natively support full NTFS write access in the way most people expect. So if something goes wrong during writing, unplugging, remounting, or a messy shutdown, the result can be missing files, corrupted folders, or a drive that acts half-dead.

I used to think, yaar, it’s just a tiny utility, how bad can it be? Turns out pretty bad if that drive has your only copy of important data.

The first fix I’d try on Windows

If your drive is NTFS, the cleanest first step is to connect it to a Windows PC and run CHKDSK. Windows understands NTFS properly, so it has the best chance of repairing basic file system errors.

If you don’t have a Windows machine, borrow one if possible. On older Intel Macs, Boot Camp may still be an option. On newer Apple Silicon Macs, that’s not the simple route anymore, so using a real Windows PC is usually easier.

Steps to repair the drive with CHKDSK

1. Connect the NTFS drive to a Windows PC.

2. Open the Start menu, search for Command Prompt, then run it as administrator.

3. Type this command and press Enter:

   chkdsk G:

   Replace G: with your actual drive letter.

4. Let Windows scan the drive. If it reports errors, run:

   chkdsk /f G:

5. Wait for the repair process to finish fully. Don’t unplug the drive halfway through, even if it feels stuck.

6. Open the drive in File Explorer and check whether your files are back in their original folders.

Quick reference

Task	Command	What it does
Scan the drive	chkdsk G:	Checks the NTFS file system for errors
Fix file system errors	chkdsk /f G:	Repairs logical file system issues
Advanced scan for bad sectors	chkdsk /r G:	Looks for physical disk problems, takes much longer

Best for: Drives that suddenly show missing files, broken folders, or weird NTFS behavior after using Mounty.

Skip if: The drive is making clicking sounds, disconnecting constantly, or not being detected properly. That points more to hardware trouble than a simple file system issue.

If CHKDSK doesn’t bring the files back

Sometimes CHKDSK fixes the structure but not the visible file list. Sometimes it repairs what it can and leaves recovered fragments in hidden folders like FOUND.000. And sometimes the damage is beyond a basic repair.

If that happens, don’t keep experimenting with random tools. That’s how people turn recoverable data into actually lost data.

What I’d do next

• Stop writing to the drive completely.
• Try a proper data recovery tool on Windows.
• If the data is truly important, clone the drive first before recovery.
• If the drive has physical issues, consider a professional recovery service.

I’m not going to pretend every free method works. It doesn’t. If CHKDSK fails, you may need a paid recovery tool. That’s still cheaper than losing years of photos or client files because of one “free” shortcut.

Common mistake that makes this worse

The big mistake is continuing to use the disk after files disappear. People reconnect it to the Mac, copy new data, try more write operations, or run random “repair” apps they found in a forum thread from 2017. Please don’t.

Deleted or missing data is often still recoverable until it gets overwritten. Once new data lands on those sectors, your chances drop fast.

Why I don’t recommend Mounty for important drives anymore

I used to recommend free NTFS tools to people who only needed a quick transfer. I don’t anymore. Here’s why. The savings are tiny compared to the risk if the drive holds important work, family photos, project archives, or your only backup.

Mounty may still work fine for some people. Fair enough. But if your setup matters, “works for some people” is not a standard I’d bet my data on.

Safer options going forward

You’ve got two sensible paths now.

Option	Good for	Main downside
Use a paid NTFS driver for Mac	People who must keep the drive in NTFS and regularly write from macOS	Costs money, and you still need to trust third-party software
Reformat the drive to exFAT	People who use both Mac and Windows and want broad compatibility	Requires backing up and erasing the drive first
Keep NTFS as Windows-only	People who mainly use Windows and only read files on Mac occasionally	Not convenient for two-way file editing on Mac

Best for most people: exFAT, if you need one external drive to work on both Mac and Windows.

Skip if: You rely on NTFS-specific permissions, Windows system use cases, or large workflows that are already tied to NTFS.

What I’d actually do

If this was my drive and the data mattered, I’d connect it to Windows first, run chkdsk /f, and check the file structure. If that failed, I’d stop immediately and move to recovery. After getting the files back, I’d back everything up and reformat the drive to exFAT unless I had a very specific reason to stay on NTFS.

Final word

If your files disappeared after using Mounty NTFS, don’t panic yet. This kind of issue is often repairable, and CHKDSK is the first thing I’d try because it’s simple and it works more often than people think.

But honestly, I wouldn’t trust Mounty again for any drive that matters. Recover the data, back it up properly, and switch to a setup that won’t give you this same headache next month in the middle of a rainy night.
