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.

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.

Mac Hard Drive Crash Recovery Questions

What should I do first after a Mac hard drive crashes?
Stop writing to the drive. If it makes unusual noises or keeps disconnecting, shut it down rather than testing it repeatedly.
How can I tell whether the hard drive failure is logical or physical?
Logical failures often leave the device visible in Disk Utility, though its volume may not mount. Clicking, grinding, no spin, burning smells, or frequent disconnections point toward physical or electronic trouble.
Can Disk Drill recover files from a Mac that will not boot?
Yes, if the storage can still be detected. Connect the drive to another Mac, boot from separate storage, or scan a byte-to-byte image rather than installing recovery software on the affected disk.
Should I run Disk Utility First Aid before using recovery software?
Create a backup image first when the files are valuable plus the disk is unstable. First Aid changes file-system structures, so recovery before repair is the more cautious order for a badly damaged volume.
Does Disk Utility First Aid delete files?
First Aid is designed to repair directory plus formatting errors, not delete personal data. Still, any repair on a damaged file system carries some risk, which is why a current backup or disk image matters.
Can I recover files if the drive does not appear in Finder?
Possibly. Check Disk Utility with Show All Devices enabled. A disk visible there may still be scanned or imaged even if Finder cannot mount its volume.
What if the crashed drive does not appear in Disk Utility?
Test another cable, port, power adapter, or enclosure if it is external. If no Mac detects the physical device, software is unlikely to help, so consider a professional lab.
Can I recover a FileVault-encrypted Mac drive?
Recovery usually requires the login password or FileVault recovery key. Without either credential, recovered encrypted sectors will not produce readable personal files.
Is it safe to reinstall macOS after a hard-drive crash?
Reinstalling may help when macOS files are damaged, but recover important data first. Never erase the drive unless your files are backed up or you have accepted their loss.
Will reinstalling macOS remove my personal files?
Apple’s standard reinstall process is intended to preserve apps plus personal data, but storage damage can make the outcome less predictable. Back up or recover files before starting whenever possible. (support.apple.com)
Can Time Machine restore everything after replacing the drive?
It can restore data included in the selected backup, including user files, apps, plus account information. Anything created after that backup needs another recovery source.
Where should I save recovered files?
Use a healthy physical disk, never the source drive. Saving onto the crashed disk may overwrite other recoverable data.
Why should I create a byte-to-byte disk image?
An image preserves readable sectors in one pass, letting you scan the copy instead of repeatedly stressing the original device. It also gives you a fixed recovery source if the drive deteriorates later.
Can an SSD be recovered the same way as a hard drive?
Some steps overlap, but SSD recovery can be complicated by TRIM, encryption, soldered storage, plus controller failure. Deleted files may disappear quickly once TRIM clears their blocks.
How long does a Mac hard drive recovery scan take?
A healthy small drive might finish within an hour. Large, slow, or damaged drives can take many hours, while repeated stalls suggest that imaging or professional help may be safer.
Why are some recovered files corrupted?
Part of the file may have been overwritten, unreadable, or missing from damaged sectors. A visible filename does not guarantee that every block belonging to the file survived.
When is professional Mac data recovery worth the cost?
Use a lab for irreplaceable work, family media, financial records, or other files whose value exceeds the recovery quote. It is also the proper route for clicking drives, failed electronics, impact damage, plus undetected storage.
