How do I recover my broken Macbook hard drive?

What causes a Macbook hard drive to break?

There are several potential causes for a Macbook hard drive failure:

  • Physical damage – If the Macbook is dropped, experiences a liquid spill, or is exposed to extreme temperatures, the hard drive components can become damaged.
  • Logical corruption – Errors in the file system or directory structure can prevent the drive from being read by the operating system.
  • Bad sectors – Over time, parts of the drive platter can fail, leading to bad sectors that cannot reliably store data.
  • Mechanical failure – Problems with the motor, heads, or other internal components can cause the drive to stop working.
  • Power surge – Sudden power interruptions can fry the drive’s circuitry or electronics.

Macbook hard drives are fragile and can fail unexpectedly. Making regular backups is crucial to avoid permanent data loss when a drive fails.

How can I diagnose a failed Macbook hard drive?

Here are the common symptoms of a failed or failing Macbook hard drive:

  • The Mac won’t turn on or boot up
  • You hear clicking or beeping noises from the hard drive
  • Files and data cannot be accessed or opened
  • Everything runs slowly as the drive has difficulty reading files
  • SMART tool shows errors or bad sectors
  • The flashing question mark folder appears at startup
  • Frequent crashes, freezes, or application errors

If you are experiencing any of these issues, it likely indicates a problem with the Macbook’s hard drive. Running Apple’s built-in diagnostics or Disk Utility can help confirm the drive is faulty.

How can I recover data from a damaged Macbook hard drive?

If the drive is physically damaged or has mechanical failure, you will need professional data recovery services. However, if the drive has logical corruption or bad sectors, you may be able to recover data yourself using recovery software or by repairing the drive. Here are some options:

  • Data recovery software – Programs like Disk Drill and Stellar Data Recovery can scan the drive and recover retrievable files.
  • Repair the drive – Disk Utility can fix simple filesystem errors. More advanced repair tools like Alsoft DiskWarrior can rebuild directories.
  • Send to data recovery pros – For physical damage or complex logical failures, professional recovery can physically repair drives in a dust-free cleanroom to extract data.
  • Salvage still-working parts – If only certain sections of the drive are damaged, you may be able to mount it as an external drive and copy data from any still-readable sectors.

The best recovery method depends on the extent and type of damage. If DIY software scanning does not recover enough data, professional recovery services may be warranted, despite their higher cost.

How can data recovery services access my data?

Professional data recovery services use specialized techniques and tools to attempt restoring data from failed drives:

  • Imaging – The drive is cloned byte-by-byte to create a full forensic copy. All recovery work is done on the clone, not the original.
  • Clean room – Recovery is done in an ESD-controlled cleanroom, necessary for mechanical drive repairs.
  • Head swaps – The drive’s read/write heads are swapped from identical donor drives to bypass head crashes.
  • Logical reconstruction – Filesystem corruption is repaired and directories rebuilt to make files accessible again.
  • Microsoldering – Where needed, ROM chips and PCB controller boards are carefully repaired via microsoldering.
  • Data extraction – Once repaired, custom software extracts every possible bit of data from the repaired drive.

With the right tools and skills, data recovery specialists can often salvage data even from drives with substantial physical damage or corruption. The techniques allow access to retrieve files when the drive does not mount or function normally.

How much does Macbook hard drive recovery cost?

The cost for Macbook hard drive recovery can range considerably based on the severity of damage:

  • Less than $500 – Logical recoveries where the drive still partially works.
  • $500 to $1500 – More complex recoveries requiring electronics repairs.
  • Over $1500+ – Recoveries from severe physical damage like burnt, corroded, or platters that need transplanting.

Here are some factors that influence Macbook hard drive recovery pricing:

  • Type of failure – Logical, mechanical, physical damage all vary in complexity.
  • Extent of damage – More damaged and unresponsive drives are more difficult to recover from.
  • Recovery method needed – Head swaps or platter transplants add more specialized labor.
  • Speed of service – Expedited recoveries within 1-2 days have higher costs.
  • Clean room usage – The overhead of a sophisticated cleanroom adds to the base cost.
  • Return of failed drive – Some companies charge an additional fee to return your old failed drive after the recovery.

Getting quotes from multiple recovery companies is recommended. Look for certified cleanroom facilities and experienced engineers when comparing quality.

Can I DIY a Macbook hard drive recovery?

Doing a DIY recovery of a Macbook hard drive is challenging but can be attempted in certain failure scenarios:

  • Runs free data recovery software like Disk Drill to see if it can read the drive and recover files.
  • Try Disk Utility’s First Aid to check and repair the drive if it mounts at all.
  • Use terminal tools like fsck and data recovery utilities like Testdisk.
  • Remove the hard drive and connect it to another Mac externally via SATA to USB.
  • Research the drive model for specialized repair guides if experienced with electronics.

However, DIY recoveries should be avoided if:

  • The drive has physical damage visible to the naked eye.
  • You hear odd mechanical sounds like clicking or grinding.
  • The drive does not spin up or mount in any computer.
  • Drive has burnt circuit board smell or visible scoring/corrosion.

In these scenarios, you are likely to further damage the drive and lose more data. Let professional engineers handle such drives through proper cleanroom recovery.

How can I avoid Macbook hard drive failures?

You can minimize the chances of a catastrophic Macbook hard drive failure by:

  • Always eject and disconnect drives properly rather than just powering off.
  • Use surge protectors and avoid questionable power sources.
  • Handle laptop carefully and avoid bumps, drops, liquids.
  • Do not move laptop when drive is active/reading.
  • Keep up to date with macOS and software updates.
  • Monitor drive health and replace when over 3 years old.
  • Maintain backups! – CrashPlan, Time Machine, cloud storage.

Catching drive problems early is also beneficial. Tools like SMART scanners and data recovery software can often fix developing issues before failure.

But ultimately hard drives are mechanical devices with finite life spans. Having recent backups and recovery options ready for when failure eventually occurs is wise.

Can lost data be recovered after replacing the failed Macbook drive?

Once a failed Macbook hard drive is replaced or the OS is reinstalled, recovering any lost files becomes much more difficult, but is still possible in some scenarios:

  • The old drive is still intact – A professional recovery company can still extract data from it.
  • You have a recent Time Machine backup – Files can be restored from the backup.
  • Copies of lost files exist on other devices – Sync services may have copies stored in the cloud.
  • Deleted files are recovered with undelete tools – Until overwritten, disk space can sometimes be scanned for deleted files.
  • Lost partition is recovered – If the drive was repartitioned, the old partition might still retain recoverable data.

However, if no backups or secondary copies exist, and no recovery attempt was made from the original failed drive before replacement, the lost files are likely unrecoverable. This demonstrates the crucial need for backups.


Recovering lost data from a failed Macbook hard drive is often possible with the right tools, techniques, backup strategies, and professional help if needed. Following best practices for drive maintenance, monitoring health, avoiding physical damage, and regular backups will minimize risk. But in the event of failure, understanding the options for repairs, recovery services, and DIY software can help your important files be rescued from an unbootable drive.
