My external hard drive was working fine, but now a large folder of photos, videos, and work files suddenly disappeared. The drive still shows up on my computer, but the missing files are nowhere to be found, and I’m worried they may have been deleted or corrupted. I need help figuring out whether external hard drive data recovery is still possible and what steps I should take first to avoid making things worse.
If your external drive still mounts and looks normal in Windows, I would not assume the files are gone. I’ve seen this happen after file system damage, where the disk shows up fine but folders look empty.
First thing, stop writing to the drive right now. Don’t format it. Don’t move new files onto it. I would also hold off on CHKDSK until your data is copied out, because repair tools sometimes change the same areas you’re trying to recover.
A few quick things I’d check before doing anything bigger:
- Turn on Hidden items in File Explorer.
- Look at the drive properties and see whether used space is close to what you expect.
- Swap the USB port or cable if the drive has been disconnecting or acting flaky.
If the files still don’t show and you don’t have a backup, I’d go straight to recovery software. I’ve had decent results with Disk Drill. It works with most common file systems, lets you preview what it finds, and one part I like is the option to make a disk image first. If the drive feels unstable, working from an image is safer than scanning the original disk over and over.
What I’d do:
- Install Disk Drill on your main internal drive, not on the damaged external one.
- Open it, pick the external drive, then hit Search for lost data.
- Run Universal Scan. In my experience, it finds more than the narrower scan modes.
- Let it finish. Preview what turns up, then recover everything to a different drive.
On Windows, the free limit is 100 MB. That’s enough for a test run so you can see whether your missing files are still there before you spend time or money.
One more thing. If the drive starts clicking, drops connection every few minutes, stops being detected, or the scan freezes and never completes, I’d stop messing with it. At that point it feels more like hardware failure than file system damage, and pushing it harder makes recovery worse.

If the drive still mounts, your odds are better than if it was dead or clicking. So yes, recovery is still possible.
I agree with @mikeappsreviewer on one big point. Stop using the drive. I’d add two checks he did not mention.
First, search from the root of the external drive with wildcards. Try file names, file types, and date filters. Sometimes a folder entry breaks, but the files still sit elsewhere on the volume. Also check the Recycle Bin on both your PC and the external drive setup, because Windows gets weird with removable storage somtimes.
Second, look in Event Viewer, Windows Logs, System. Filter for Disk, Ntfs, and Kernel-PnP errors around the time the folder vanished. If you see repeated I/O errors or surprise removal events, this points to a bad cable, weak USB power, or early drive failure. That changes what you should do next.
I slightly disagree with skipping checks forever. CHKDSK is risky first, yes. But after you image or recover what matters, run it to see if the file system damage is bigger than one missing folder.
If you need recovery software, Disk Drill is a solid option because it previews results well and handles deleted plus lost partitions in one app. Test scan first, then recover to another disk.

One more thing. If the used space dropped by the same size as the missing folder, it was likely deleted or the directory got damaged. If used space stayed the same, your files are often still there, hidden from the file table. That’s a better scenerio for recovery.
If the drive still mounts, I’m a little more optimistic than panicked. Not saying “relax,” just saying this is often a file table problem, not instant doom.
I agree with @mikeappsreviewer and @stellacadente about not writing anything new to it, but I’d also check whether the folder was moved instead of “vanished.” Sounds dumb, happens all the time. In File Explorer, search the drive by a few exact photo/video filenames if you remember any, and sort the whole drive by Date Modified. Sometimes the parent folder disappears but the files are sitting in some weird nested path.
Also, check this from Command Prompt:
attrib -h -s -r /s /d X:\*.*
Replace X with your external drive letter. If malware or a file attribute glitch hid the folder, that command can sometimes make it visible again. Small warning, only do it on the external drive you’re troubleshooting, not random drives.
One place I slightly disagree with the usual advice: don’t spend too long “checking stuff” if the files matter a lot. Every extra reconnect, rescan, and poke at a flaky drive is a gamble. If the data is important, image it first or scan it with something reputable. Disk Drill is fine for that, esp if you want to preview recoverable files before committing. It’s one of the better options when an external hard drive shows up but files disappeared.
If the folder contains work stuff you really can’t lose, I’d skip DIY pretty fast if the drive starts lagging, disconnecting, or making odd noises. That’s the line where software recovery turns into “stop before you make it worse.”
For a quick walkthrough, this Disk Drill review and file recovery walkthrough is pretty easy to follow.
Short version: yes, recovery is still very possible. But stop using the drive now, check for hidden/relocated files, and if that fails, go straight to Disk Drill or a disk image before the sitaution gets worse.
