My hard drive suddenly stopped showing up on my computer, and I think I lost important work documents, family photos, and personal files. I need help with hard drive data recovery and want to know the safest way to recover files without making the problem worse.
I went through this once with an old 2 TB HDD, and the first mistake I made was poking at it too much. So, first step, stop using the drive now. Do not copy anything onto it. Do not install recovery apps there. Do not keep opening folders to 'check one more thing.' Every write makes recovery worse. If it holds your OS, shut down and hook it up to another computer as a secondary drive if you have the option.
Before you throw tools at it, figure out what kind of failure you have. The fix for deleted files is not the fix for a dying drive.
What I check first:
Logical trouble. Deleted files, accidental format, broken partition, RAW volume, messed up file system.
Physical trouble. Bad sectors, read errors, head issues, motor issues, weird sounds.
Run a S.M.A.R.T. check and see what the drive reports. On Windows, CrystalDiskInfo is the usual quick check. On Mac, DriveDx does the same kind of job. Look for bad sectors, reallocated sectors, pending sectors, and read error counts.
Stuff I would treat as a bad sign right away:
Repeated clicking or ticking
Grinding or scraping noise
The drive drops out while the PC is running
The whole machine hangs when you open the drive
It spins, but the system does not detect it
If you have any of those, slow down. Repeated scans on a failing mechanical drive are a good way to make it worse. I would stop there if the files matter and look at a lab like DriveSavers or Ontrack. Expensive, yep. Still cheaper than losing stuff you cannot replace.
If the drive is quiet and still shows up, try the boring checks first. People skip these and waste hours.
Look here:
Recycle Bin or Trash
Windows File History
Windows Previous Versions, right click folder, Restore previous versions
Time Machine on Mac
Cloud trash folders in OneDrive, Google Drive, Dropbox, iCloud
Email attachments, sent mail, old chat uploads
If none of those hits, move to recovery software. I’ve had decent results starting with Disk Drill. It’s fine for deleted files, formatted disks, damaged partitions, and RAW volumes. The preview feature matters more than people think. If the previews look broken, the recovery result often is too.
The safe order looks like this:
Install the recovery app on a different drive.
Connect the bad HDD as a secondary disk if possible.
Run a quick scan first.
If quick scan misses stuff, run the deeper one.
Preview files before recovering them.
Save recovered files to another disk, never back onto the same HDD.
Open the recovered files and test them. Photos, docs, videos, all of it.
If the disk has bad sectors, I’d image it first and work off the image. Sector by sector copy, then scan the copy. I learned this late, annoyngly late. If the scan crashes halfway through, you still have the original untouched as much as possible.
When I’d stop trying software:
Loud clicking
No spin-up
Drive vanishes over and over
Software sees the disk but finds nothing even though you know data was there
At that point a recovery lab is the realistic move. Typical pricing lands around $300 to $1500 or more, depending on what failed. They have cleanroom gear and donor parts. Home recovery does not.
If you want the short version, it’s this. Stop using the drive. Check S.M.A.R.T. Try backups and trash folders. Use recovery software from another drive. Recover onto another drive. If it clicks, grinds, or disappears, stop and send it out.
I’d start with the S.M.A.R.T. report first. That usually tells you if this is a file system mess or the disk is on its way out.

If the drive is not showing up at all, I would spend 2 minutes on hardware before scans. Swap the SATA or USB cable. Try a different port. Try a powered enclosure or dock if it is a 3.5-inch HDD. A weak USB port fools people all the time. I disagree a bit with @mikeappsreviewer on starting with S.M.A.R.T. every time, because if the BIOS or Disk Management does not see the drive, you need connection checks first.
Then check where it fails:
BIOS sees it, Windows does not. Likely partition, file system, or letter issue.
Disk Management sees it as unallocated or RAW. Do not format it.
Nothing sees it. More serious.
On Windows, open Disk Management and see if the disk appears with the right size. If it does, do not initialize it. That prompt traps a lot of pepole.
If the drive mounts read-only or half-works, copy the most important files first, smallest irreplaceable stuff first. Docs and photos before huge videos.
For software recovery, Disk Drill is a solid pick if the disk is detected. It handles lost partitions and deleted files well, and the preview helps you avoid wasting hours. Save output to another drive.

One more thing, if this is an SSD, do not keep rescanning it after deletion. TRIM makes old data vanish fast. Different beast.
If the drive ‘suddenly stopped showing up,’ I’d add one thing that neither @mikeappsreviewer nor @techchizkid leaned on enough: check whether this is actually an enclosure/adapter failure before you treat it like a dead hard drive. I’ve seen plenty of external HDDs look dead when the cheap USB bridge board was the real problem. Pop the drive out of the enclosure if you can and connect it directly by SATA, or try a known-good powered dock.
Also, be careful with auto-repair tools. I know people love running chkdsk the second Windows gets weird, but on a flaky drive that can make a mess fast. If the files are important, I would not let Windows ‘fix’ anything yet. Same for clicking ‘Initialize disk’ when prompted. That’s where people panic-click and then regret it.
My order would be:
- Test power, cable, enclosure, and another machine.
- Check if the drive gets warm or spins at all.
- If it appears even briefly, grab a full clone or image first if possible.
- Only then scan the clone, not the original, if the drive seems unstable.
If the drive is readable enough, Disk Drill is a reasonable choice for hard drive data recovery because it’s simple about previews and usually easier for non-tech people than some of the older tools. But I’d only use it after the connection issue stuff is ruled out. Too many pepole jump straight into scans when the USB board is the actual idiot in the room.
If you want a step-by-step Windows hard drive recovery walkthrough, this easy Windows hard drive recovery guide is more useful than a lot of text-only posts.
One thing I slightly disagree on with @techchizkid: copying files individually from a drive that ‘half-works’ is not always best if it’s degrading fast. Sometimes stressing the file system over and over is worse than doing one straight clone pass. Depends how sick the disk realy is.
If the drive is making noise, not spinning, or disconnecting every few seconds, stop DIY stuff. That’s lab territory.
