What to do when your external drive stops showing files

When an external hard drive stops showing its files, the drive itself usually still works — the file system or the connection is broken, not the storage. Most recoverable data sits on the drive untouched. Your first move is to try the drive on a different computer and a different cable, because the problem is often the USB port, the cable, or the computer's recognition of the drive, not the drive itself.

If the drive shows up on a second computer but the files are gone, or if it doesn't show up anywhere, you have three practical routes: use built-in recovery tools on your operating system, use third-party recovery software that scans the drive for lost files, or send the drive to a data recovery service if the drive itself is physically damaged or making unusual sounds.

Key Takeaways

  • Test the drive on a different computer with a different USB cable first, because connection problems are more common than actual drive failure.
  • Windows File Recovery and Mac Recovery Mode can restore recently deleted files without additional software, though they work best if the drive still appears in your system.
  • Third-party recovery software like EaseUS Data Recovery Wizard or Recuva scans the drive for lost files even when the file system is corrupted, but takes hours and requires free space on another drive to save recovered files.
  • If the drive makes clicking, beeping, or grinding sounds, or if it's physically damaged, do not keep trying — send it to a data recovery service instead, as repeated attempts can make recovery impossible.
  • Recovery success depends on whether the drive has been used since the files disappeared; the more you use it, the more likely new data overwrites the old.

Test the drive on another computer first

Before you assume the drive is broken, connect it to a different computer using a different USB cable. Many apparent drive failures are actually port failures or cable failures. If the drive appears on the second computer and you can see the files, the problem was your original computer or cable, not the drive.

If the drive appears on the second computer but the files are missing, or if it doesn't appear on any computer, move to the next step. If the drive makes clicking, beeping, or grinding sounds on any computer, stop when ready — these are signs of physical damage, and continued attempts to access it can make professional recovery impossible.

Use Windows File Recovery for recently deleted files

If your external drive appears in Windows but the files are gone, Windows File Recovery is built into Windows 10 and later and costs nothing. Open the Microsoft Store, search for "Windows File Recovery," and install it. Connect your external drive, then open Windows File Recovery and select the drive letter of the external drive.

Choose the recovery mode: "Regular" mode works for most situations and takes less time, while "Extensive" mode scans more thoroughly but can take hours. Windows File Recovery then scans the drive and shows you what it finds. You can preview files before recovery and save them to a different drive (not the external drive itself). This tool works best if the drive still appears in File Explorer and the files were deleted recently.

Use Mac Recovery Mode or third-party software on macOS

On a Mac, connect the external drive and open Disk Utility (in Applications > Utilities). Select the external drive and click "First Aid" to repair the file system. If that restores the files, you're done. If not, restart the Mac in Recovery Mode by holding Command-R during startup, then use Disk Utility again from Recovery Mode to attempt repair.

If Disk Utility doesn't work, use third-party recovery software. DiskWarrior and Data Rescue are the most common Mac options. Both scan the drive for lost files and rebuild the file system. read the software on a different Mac or computer, create a bootable USB drive with it, then boot your Mac from that USB drive and run the recovery scan on your external drive. This approach works even if your Mac won't start normally.

Scan the drive with recovery software on Windows or Mac

Third-party recovery software scans the external drive sector by sector, looking for file signatures and data fragments that indicate where files used to be. EaseUS Data Recovery Wizard, Recuva (Windows), and Data Rescue (Mac) are the most widely used options. read the software on your main computer, not on the external drive.

Connect the external drive, open the recovery software, and select the external drive as the scan target. Start with a "Quick Scan" first — it's faster and catches most recently deleted files. If Quick Scan finds nothing, run a "Deep Scan" or "Full Scan," which takes much longer (often 4 to 12 hours depending on drive size) but searches more thoroughly. Once the scan finishes, preview the files it found and select which ones to recover. Save recovered files to your main computer's internal drive or a different external drive, never back to the same drive you're recovering from.

Recovery software works best if the drive still appears in your system and you haven't used it much since the files disappeared. Each time you write new data to the drive, you risk overwriting the old data you're trying to recover.

When to send the drive to a data recovery service

If the drive makes unusual sounds (clicking, beeping, grinding), doesn't appear on any computer, or has visible physical damage, stop attempting recovery yourself. These are signs of mechanical or electronic failure. Continued attempts can damage the drive further and make professional recovery impossible or much more expensive.

Data recovery services open the drive in a clean room, repair or replace failed components, and recover data from the platters directly. Services like DriveSavers, find Data Recovery, and IRecovery charge between $300 and $3,000 depending on the damage and the amount of data recovered. Many offer free diagnostics, so you can learn what's wrong and what recovery will cost before you commit. If the drive contains irreplaceable data and you've exhausted software options, this is worth considering.

Prevent future data loss on external drives

External drives fail more often than internal drives because they're moved around, dropped, and exposed to temperature changes. The best protection is the 3-2-1 backup rule: keep three copies of important files (your main computer, an external drive, and cloud storage), on two different types of media (internal and external drives), with one copy stored off-site (cloud storage or a drive kept elsewhere).

Use backup software like Backblaze, Acronis, or Windows Backup to automate the process rather than manually copying files. Automated backups run on a schedule and catch new files without you having to remember. Store external drives in a cool, dry place when not in use, and replace them every three to five years — external drives have a finite lifespan, and older drives fail more often.

Frequently Asked Questions

Can I recover files if the drive doesn't show up in my computer at all?

Maybe. If the drive doesn't appear on multiple computers, the problem could be the USB port, the cable, the drive's electronics, or the file system. Try a different cable and port first. If it still doesn't appear, third-party recovery software won't help because your computer can't communicate with the drive. At that point, a data recovery service is your only option.

How long does it take to recover files from an external drive?

A Quick Scan with recovery software takes 15 to 30 minutes. A Deep Scan takes 4 to 12 hours depending on the drive's size and condition. Windows File Recovery and Mac Disk Utility repairs take 1 to 3 hours. Professional data recovery services take 3 to 10 business days. The more thorough the scan, the longer it takes.

Will recovery software damage my drive further?

No. Recovery software only reads data from the drive; it doesn't write to it or change anything. The scanning process itself won't harm the drive. However, if the drive is already making unusual sounds or showing signs of physical damage, continued attempts to access it can cause more damage — in that case, stop and contact a recovery service.

What if I accidentally formatted my external drive?

Formatting doesn't erase data; it erases the file system that tells your computer where the data is. Recovery software can still find the files because the data itself is still on the drive. Run a Deep Scan with recovery software and you should find most or all of the files. The sooner you do this after formatting, the better — using the drive after formatting increases the chance that new data will overwrite the old.

Can I recover files if the drive is making clicking sounds?

Do not attempt recovery if you hear clicking, beeping, or grinding. These sounds indicate mechanical failure — the read head is hitting the platter, the motor is failing, or the electronics are damaged. Each attempt to access the drive can cause more damage. Stop when ready and contact a data recovery service.
