What you can do when a hard drive stops working

If your hard drive has failed but you can still hear it spin or see it recognized by your computer, file recovery is often possible — even if the drive won't boot or open normally. The key is stopping when ready and not overwriting the drive with repeated restart attempts or repair software. Your chances depend on whether the failure is logical (corrupted files or deleted data) or physical (mechanical damage, head crash, or electronics failure). Logical failures you can sometimes handle yourself. Physical failures almost always require a professional recovery service.

The first step is diagnosis: connect the drive to another computer as an external drive using a USB adapter or enclosure, and see whether it appears in the file system at all. If it shows up but won't open, or if files are missing, you have options. If the drive makes clicking sounds, won't spin, or isn't recognized by any computer, stop and contact a recovery service — opening the drive yourself will destroy any chance of recovery.

Key Takeaways

  • Stop using the drive when ready if it makes clicking or grinding sounds, as continued operation causes physical damage that only a professional can reverse.
  • If the drive appears in your file system but won't open, recovery software can often retrieve files without professional help.
  • Professional recovery services cost $300 to $3,000 depending on damage severity, but they are the only option for mechanical failures or drives that aren't recognized by any computer.
  • Connect the failed drive to another computer as an external drive before attempting any recovery method, to avoid damaging your working system.
  • Keep backups going forward — recovery is possible but not may provide, and prevention is far cheaper than repair.

Connecting the drive to another computer safely

Before you run any recovery software, you need to access the drive without booting from it. The safest way is to connect it to a working computer as an external drive. You have two options: a USB adapter (a small device that lets you plug a bare drive into a USB port) or a drive enclosure (a case that holds the drive and connects via USB). Both cost $15 to $40 and are worth buying rather than attempting recovery on your own machine.

Remove the failed drive from your computer following your manufacturer's instructions — usually this means powering down, unplugging, and removing a few screws. Connect it to the working computer using the adapter or enclosure. If the drive appears in File Explorer or Finder as a new drive, even if it won't open normally, you can proceed to recovery software. If it doesn't appear at all, the drive has a physical failure and needs professional service.

Do not attempt to repair the drive by opening the case, cleaning contacts, or freezing it. These methods destroy more data than they save and will void any chance a professional service has of helping you later.

Using recovery software for logical failures

If the drive appears in your file system but files are missing, deleted, or the drive won't open, recovery software can often retrieve them. Common programs include EaseUS Data Recovery Wizard, Recuva (free), R-Studio, and DiskDigger. These scan the drive for file fragments and rebuild them based on file signatures — they work because deleted files usually remain on the drive until new data overwrites them.

Install the software on your working computer, not on the failed drive. Connect the failed drive as external, launch the software, and select the failed drive as the scan target. Let it run a full scan, which can take hours depending on drive size. The software will show you what it found. Preview files before recovery to confirm they're intact. Once you're satisfied, recover them to a different drive — never back to the same drive you're recovering from.

Recovery software works best on drives that were recently wiped, drives with corrupted file systems, or drives where files were deleted but not overwritten. It works poorly on drives with physical damage, drives that have been running with errors for months, or drives where new data has already overwritten the old. If the software finds very little, the drive likely has physical damage.

When to stop and call a professional

Professional data recovery services use specialized tools, clean rooms, and replacement parts to recover data from physically damaged drives. They can replace failed circuit boards, repair mechanical damage, and extract data from drives that no computer will recognize. This costs $300 to $3,000 depending on damage severity — a straightforward circuit board replacement might be $300, while a head crash requiring platter replacement might be $1,500 or more.

You need professional service if any of these explore: the drive makes clicking, grinding, or beeping sounds; the drive doesn't spin or makes no sound at all; the drive isn't recognized by any computer even when connected as external; recovery software finds almost nothing; or the data is critical enough that you can't risk further damage. Do not open the drive case, do not attempt to clean contacts, and do not run recovery software repeatedly — each attempt reduces your chances of professional recovery.

Find a service by searching "data recovery" plus your city name, or ask your computer repair shop for a referral. Most services offer free diagnostics — they'll tell you what's wrong and what recovery costs before you commit. Get quotes from at least two services. Avoid services that may provide recovery or charge upfront before diagnosis; legitimate services charge only if they succeed.

Recovery software options and what they cost

Recuva is free and works well for straightforward deletions on Windows drives. It's a good first step if you have no budget. EaseUS Data Recovery Wizard costs $70 to $100 for a license and handles more complex failures, including formatted drives and drives with corrupted file systems. R-Studio costs $80 to $200 and is more powerful but has a steeper learning curve. DiskDigger is free for basic recovery and $30 for the full version.

Most of these offer a free scan so you can see what they find before you pay. Run the free scan first — if it finds your files, you know recovery is possible. If it finds almost nothing, the drive has physical damage and software won't help. Buy a license only if the free scan shows promise and you're comfortable waiting several hours for a full recovery.

Preventing data loss on your current drives

Hard drives fail without warning. A drive that works perfectly today can fail tomorrow. The only protection is backup — ideally two backups, one local and one off-site. Local backup means copying important files to an external drive you keep at home; this protects against accidental deletion but not against theft or fire. Off-site backup means cloud storage like Google Drive, OneDrive, or Backblaze; this protects against physical loss but requires internet bandwidth.

Set up automatic backup so you don't have to remember. Windows includes File History (built-in, free) and Backup and Restore. Mac includes Time Machine (built-in, free). Both work with an external drive and run automatically on a schedule you set. For cloud backup, Backblaze costs $7 per month for unlimited storage and runs in the background. For most people, local backup plus cloud backup of critical files is the right balance.

Check your backups occasionally — a backup that's never been tested is just a drive taking up space. Restore a few files to confirm they actually work. If you don't have backups and your drive fails, you'll face the choice between paying for recovery or losing the data. Prevention is always cheaper.

Frequently Asked Questions

Can I recover files if the drive makes clicking sounds?

No — clicking usually means the read head is hitting the platter, and each click causes more damage. Stop using the drive when ready and contact a professional recovery service. Running recovery software or continuing to use the drive will make the damage worse and may make recovery impossible.

How long does data recovery take?

Recovery software can take 4 to 12 hours depending on drive size and damage. Professional services usually take 3 to 7 business days. Some services offer rush service for an extra fee. Ask about timeline when you contact them.

Will recovery software work on a Mac or Linux drive?

Yes, most recovery software works across file systems. EaseUS and R-Studio handle Mac drives (HFS+), Windows drives (NTFS and FAT32), and Linux drives (ext4). Recuva works primarily on Windows but can sometimes read Mac drives. Check the software's specs before buying.

What if I recovered files but they're corrupted or won't open?

Partial recovery is common — the software found the file but not all of it, or the file system was too damaged to rebuild it completely. Try opening the file anyway; some files are partially readable. If it won't open, the file is too damaged. If you have a backup, use that instead.

Is it worth paying for professional recovery if I don't have backups?

That depends on what the data is worth to you. If it's family photos, business records, or anything irreplaceable, professional recovery is worth the cost. If it's software you can reinstall or files you can recreate, it probably isn't. Get a free diagnostic quote first — you'll know the cost before you decide.
