How to Recover Crashed Hard Drive on Mac?

A crashed drive does not always mean the files are gone. The right approach depends on whether the problem is logical, physical, or simply a broken macOS installation.

Quick answer

Stop using the affected drive first. If it remains visible in Disk Utility without clicking or disconnecting, create a byte-to-byte image with Disk Drill, then scan that image. Use a professional lab when the drive makes unusual noises or vanishes from every Mac.

Do not erase, initialize, repartition, or reinstall onto the crashed drive before recovering your files. Stop powering it on if you hear clicking, grinding, or repeated spin-up cycles. Extra attempts can turn limited physical damage into permanent loss.

When Software Should Not Scan a Crashed Mac Drive

Do not start a deep scan when a hard drive clicks, grinds, disappears during reads, or becomes unusually hot. Scanning places sustained demand on the device, which is a bad trade if its mechanical parts are failing.

A drive that suffered a fall, power surge, or liquid spill belongs with a recovery lab. Keep it powered off, note what happened, then avoid well-meant experiments.

Top 5 Methods to Recover a Crashed Hard Drive on Mac

01

Create a Disk Image and Scan It With Disk Drill

Best first move when the drive still appears in Disk Utility without severe physical symptoms

~30–120 min
Difficulty Easy
You need Disk Drill plus healthy storage
Works for Internal or external Mac drives

Use this route if macOS can still detect the crashed drive, even when it will not mount or open. Disk Drill can create a byte-to-byte image, scan the image for recoverable files, then preview results before recovery. (reddit.com)

  1. Stop saving files, installing apps, or repeatedly restarting from the damaged drive.
  2. Connect a healthy external disk with more free space than the amount of data you expect to recover. Install Disk Drill on that healthy disk or another Mac, not on the crashed drive.
  3. Open Disk Drill, select Byte-to-byte Backup, choose the problem drive, then save its image to healthy storage.
  4. Return to Storage Devices, attach the new disk image, then select Search for lost data.
  5. Filter the results by file type or date. Preview several important files to check whether they open correctly.
  6. Select the files you need, click Recover, then save them to a different physical drive.

Run Disk Utility First Aid From macOS Recovery

Useful for directory or file-system trouble rather than mechanical drive failure

~10–45 min
Difficulty Easy
You need macOS Recovery
Works for Mac startup disks plus external drives

First Aid checks formatting plus directory structures, fixing certain logical errors that stop a disk from mounting or starting macOS. It cannot repair failing hardware, so do not keep rerunning it on a drive that clicks, disappears, or reports imminent failure. (support.apple.com)

  1. Shut down the Mac. Disconnect unneeded USB devices while leaving the affected external drive attached, if applicable.
  2. Start macOS Recovery. On Apple silicon, hold the power button until startup options appear. On an Intel Mac, turn it on while holding Command-R .
  3. Choose Disk Utility, then select View > Show All Devices.
  4. Run First Aid on each volume first, followed by each container, then the physical device at the top of the hierarchy.
  5. Restart the Mac if First Aid reports that the disk is OK or was repaired. Copy valuable files to another disk immediately.
i If First Aid fails, prioritize file recovery before erasing, repartitioning, or reinstalling macOS.

03

Copy Files Through Share Disk or Target Disk Mode

A practical option when the failed Mac will not boot but its storage remains readable

~20–90 min
Difficulty Moderate
You need Second Mac plus compatible cable
Works for Boot failures with readable storage

A Mac that cannot load macOS may still expose its internal storage to another Mac. Apple silicon Macs use Share Disk in Recovery, while many Intel models support Target Disk Mode.

  1. Connect the failed Mac to a working Mac with a compatible Thunderbolt or USB cable.
  2. On Apple silicon, enter macOS Recovery, choose Utilities > Share Disk, select the internal volume, then click Start Sharing.
  3. On a compatible Intel Mac, start it while holding T to enter Target Disk Mode.
  4. On the working Mac, open Finder, locate the shared or attached disk, then copy the most valuable folders first.
  5. Save everything to the working Mac or a separate external disk. Open a sample of copied photos, documents, plus videos before assuming the transfer worked.
i A FileVault-protected disk may require the account password or recovery key before its files become accessible.
04

Restore the Mac From a Time Machine Backup

The safest route when a usable backup predates the hard-drive crash

~1–6 hr
Difficulty Easy
You need Time Machine backup
Works for Replacement or repaired startup disks

Time Machine can return personal files, apps, plus account settings after the disk has been replaced or macOS has been reinstalled. Apple directs users to reinstall macOS first when a flashing question mark shows that no usable startup system is available. (support.apple.com)

  1. Connect the Time Machine backup disk to the Mac.
  2. If the original storage failed physically, replace it or have the Mac serviced before continuing.
  3. Start macOS Recovery, choose Reinstall macOS, then follow the installer without erasing any potentially recoverable disk unless your files are already safe.
  4. During setup, choose the option to transfer information from a Mac, Time Machine backup, or startup disk.
  5. Select the latest healthy backup from before the crash, choose the data categories, then begin the transfer.
  6. After setup finishes, check recent work separately. Files created after the final backup will need another recovery method.
i Do not overwrite the only surviving copy of a backup while troubleshooting the original drive.

05

Send the Drive to a Data Recovery Lab

The right choice for clicking, impact damage, failed electronics, or an undetected device

~3–14 days
Difficulty Easy to submit
You need Recovery budget plus secure packaging
Works for Physically failed HDDs or inaccessible SSDs

Software cannot recover a disk that no longer communicates reliably with the Mac. A specialist may work around damaged heads, electronics, firmware, or media, though no lab can promise that every file will survive.

  1. Power down immediately if the drive clicks, grinds, smells burned, suffered liquid exposure, or repeatedly spins up then stops.
  2. Do not open the drive casing, freeze it, tap it, swap random circuit boards, or run long scans.
  3. Record the Mac model, drive model, symptoms, encryption status, plus the folders that matter most.
  4. Contact a lab that offers an evaluation, a written quote, secure handling, plus a clear policy for unsuccessful recovery.
  5. Pack an external drive in an anti-static bag with firm padding. For a built-in Mac drive, ask whether the whole computer should be shipped.
  6. When the lab returns recovered data, copy it to two separate storage locations before sorting or deleting anything.
i For encrypted storage, the lab may need your FileVault password or recovery key to produce usable files.

Choose the Safest Recovery Route for Your Mac Drive

Creating an image, then scanning it with Disk Drill is the sensible first move when the crashed drive is still detected plus physically stable. First Aid may fix a logical structure problem, while Share Disk can rescue files from a Mac that merely stopped booting.

Use Time Machine when a recent backup already contains what you need. Skip home troubleshooting entirely if the drive clicks, drops offline, or has impact or liquid damage.

Recover irreplaceable files first, save them to a separate physical disk, then verify several files before attempting repairs on the original drive.

Mac Hard Drive Crash Recovery Questions

How do I know if my Mac hard drive actually crashed or just stopped mounting?
Check whether Disk Utility can see the drive. If it appears but will not mount, the issue may be file system damage, not full hardware failure. If it does not show up at all, the problem is more likely hardware related.
What is the first thing I should do after my Mac hard drive crashes?
Stop using the drive right away. Every write can make recovery harder, so avoid reinstalling macOS, running repair loops, or copying new files onto it until you know the damage level.
Can I recover files from a crashed hard drive on a Mac myself?
Yes, if the drive is still detected by the Mac and the damage is logical rather than physical. Start with Disk Utility, then use recovery software or a clone of the drive before trying more advanced repair steps.
Should I use Disk Utility First Aid on a crashed Mac hard drive?
Only if the drive still mounts or at least appears in Disk Utility. First Aid can fix minor directory problems, but on a failing drive it can also stress the disk, so use it carefully.
How do I recover data from an external hard drive that crashed on a Mac?
Connect it directly to the Mac with a known good cable, then check Disk Utility. If it is detected, try copying important files first, then use recovery software if folders are missing or unreadable.
What should I do if my Mac says the disk is unreadable?
Do not initialize or erase it if you still need the files. Cancel the prompt, then inspect the drive in Disk Utility to see whether it can be mounted, repaired, or scanned by recovery software.
Can Time Machine help after a hard drive crash on Mac?
Yes, if your files were backed up before the crash. You can restore whole folders or the entire system from Time Machine, which is usually faster and safer than raw recovery from a failing drive.
How do I clone a failing Mac hard drive before recovery?
Use cloning software that can copy unreadable sectors and skip damaged areas. Clone the failing drive to a larger healthy drive, then run recovery on the clone instead of the original.
Is it safe to keep trying to mount a crashed hard drive on Mac?
A few attempts are usually fine, but repeated mounting can make a weak drive worse. If you hear clicking, grinding, or repeated spin-up failures, stop and move to professional recovery.
What file recovery software works best for a crashed Mac hard drive?
Look for tools that support APFS, HFS+, external drives, and raw scan recovery. Good options can preview files before restore, which helps you avoid wasting time on junk results.
Why does my Mac hard drive show the wrong size after crashing?
That can happen when the partition table or file system is damaged. The disk may still contain recoverable data, but the structure that tells macOS how to read it has become corrupted.
Can I recover data if my Mac hard drive is making clicking sounds?
Sometimes, but this is a strong sign of mechanical failure. Power it off, do not keep rebooting it, and contact a data recovery lab if the files are important.
How much does Mac hard drive recovery usually cost?
Software recovery can be inexpensive if the drive is still readable enough to scan. Professional cleanroom recovery costs much more, especially if the drive has physical damage or requires part replacement.
What is the difference between logical failure and physical failure on a Mac hard drive?
Logical failure means the drive works physically but the data structure is damaged. Physical failure means the hardware itself is failing, such as a dead motor, bad heads, or electronics damage.
Can I recover deleted files from a crashed Mac hard drive?
Sometimes, but only if the deleted data has not been overwritten. If the drive is unstable, avoid installing recovery software on it and run scans from another Mac or an external boot drive.
How do I get files off a Mac hard drive that will not boot?
Boot from another macOS drive, recovery mode, or an external installer, then connect the failed drive as a secondary disk if possible. If the Mac still detects it, you may be able to copy files directly or use recovery tools.
Should I erase a crashed hard drive on Mac before trying to recover it?
No. Erasing destroys the structure recovery tools need, which can wipe out file traces that might still be recoverable. Only erase after you have copied everything you can save.
What if Disk Utility cannot see my Mac hard drive at all?
Try a different cable, port, or enclosure first if it is an external drive. If the drive still does not appear, the issue is likely hardware level, which often needs professional service.
Are SSD recovery steps different from hard drive recovery on a Mac?
Yes. SSDs can fail in ways that make recovery harder because data can disappear fast once the controller or memory chips fail. Also, TRIM can reduce the chances of recovering deleted files.
What is the safest way to prevent another Mac hard drive crash after recovery?
Keep a current backup with Time Machine plus at least one extra copy on another drive or cloud service. Also watch for early warning signs like slow transfers, beachballs, unexpected disconnects, or repeated errors so you can replace the drive early.
