Back Up Your Data Regularly
It’s critically important to back up your data regularly to avoid permanent data loss if your SSD fails or needs to be erased. The best way to back up a Mac is using Apple’s Time Machine software. Time Machine automatically saves hourly backups of your files to an external hard drive or network location. This lets you restore your entire system or individual files if needed.
You can also manually back up important files and folders to external drives, cloud storage services like iCloud, or tools like Carbon Copy Cloner. Backing up to multiple destinations provides redundancy. For example, use Time Machine for hourly backups plus a weekly manual backup to an external drive stored offsite.
Set up a regular backup schedule appropriate for your usage. Frequently changing files may need daily or hourly backups. Files that rarely change can be backed up weekly or monthly. The key is having current backups available so you can fully restore your data if your SSD fails or needs to be erased for any reason.
Understand SSDs vs HDDs
SSDs (solid state drives) and HDDs (hard disk drives) store data differently, which impacts their performance and cost. HDDs rely on platters, spindle motors, and read/write heads to access data mechanically. This makes them slower and more prone to failure from shock or vibration. SSDs use integrated circuits to store data electronically with no moving parts, allowing much faster read and write speeds. However, SSD storage costs significantly more per gigabyte compared to HDDs. Generally, SSDs provide faster boot times, application launches, and data transfers, while HDDs offer more storage capacity for the price (Source).
Move Data to a New Drive
If your Mac’s SSD is getting full or you want to back up your data, you’ll need to move files to a new external drive. Here are some steps for moving data off your Mac’s SSD:
Using Disk Utility:
- Connect the external drive to your Mac using a USB, Thunderbolt, or FireWire cable.
- Open Disk Utility on your Mac. You can find it by searching in Spotlight or going to Applications > Utilities.
- Select your Mac’s SSD on the left side of Disk Utility.
- Click the “Restore” tab at the top.
- Drag the icon for your external drive to the “Destination” field.
- Check the boxes to replace existing data on the destination drive.
- Click “Restore” and your Mac’s SSD will be cloned to the external drive.
Using migration software:
- Apps like Carbon Copy Cloner allow you to selectively copy files or folders to an external drive.
- Open Carbon Copy Cloner and select the folders or files you want to copy.
- Select your external drive as the destination.
- Schedule or start the copying process. The software will only copy your selected data.
This migration software makes it easy to free up space on your SSD by moving specific files, folders, or apps over to an external drive.
Access Data After SSD Failure
If your SSD has completely failed and you can no longer access the data, you have a few options to try to recover your files:
Professional data recovery services – There are companies like CleverFiles and iBoysoft that specialize in data recovery from failed drives. They have sophisticated tools and clean room facilities to physically repair drives and extract data. However, these services can cost $500-3000+ depending on the extent of the drive damage.
DIY data recovery software – Software like Wondershare Recoverit provides an affordable DIY option to scan and extract data from failed drives. While cheaper than professional services, the success rate depends on the severity of SSD failure. Physical damage may prevent software-based recovery.
If the SSD is not physically damaged, DIY software provides a more affordable way to access data. But with a completely dead SSD, professional recovery likely offers the highest chance for data retrieval. Just be prepared for high costs and no guarantees.
Remove and Reinstall SSD
If your SSD has failed or is no longer functioning properly, you may need to physically remove it and replace it with a new SSD. Here are the steps to safely remove and reinstall an SSD in your Mac:
1. Shut down your Mac and unplug all connected cables and devices.1
2. Place your Mac on a flat, stable surface and ground yourself by touching a metal part of the computer’s frame. This prevents static discharge which could damage components.
3. Remove the bottom case of your Mac to access the SSD using the appropriate screwdriver. Refer to Apple’s service manuals for your specific Mac model.
4. Locate the SSD module and gently remove it from the logic board slot. Do not pull it out at an angle.
5. Insert the new SSD module into the same slot, pressing down carefully until it clicks into place.
6. Replace the bottom case and screw it back on securely.
7. Reconnect devices and cables, then restart your Mac. The new SSD should be detected.
Following proper electrostatic discharge procedures is critical to avoid permanently damaging your Mac’s logic board or components. If you are uncomfortable performing these steps, seek help from Apple Support or a qualified technician.
Encrypt SSD Before Disposal
It’s important to securely wipe your SSD before disposing of it to prevent sensitive data from falling into the wrong hands. When you delete files on your Mac, the data isn’t actually erased – only the directory of where the data is stored is removed. This means someone could potentially still recover your deleted files from the SSD using data recovery software.
To prevent this, you should encrypt your SSD before disposal. Here are the steps to securely wipe an SSD on a Mac (MacObserver):
- Launch Disk Utility
- Select the disk (boot SSD)
- Select “Unlock” from the File menu
- Enter the password you set up previously
- Click “Erase” and select a secure erase option like multi-pass erase to thoroughly wipe the SSD
After securely erasing, your data will be cryptographically erased and irrecoverable. You can then dispose of or reuse your old SSD without worry that sensitive files could be accessed.
Troubleshoot Slow SSD Issues
If you notice your SSD running slower than expected, there are several troubleshooting steps you can take to try and restore full performance:
First, make sure your Mac is updated with the latest software updates. Go to the App Store app and click on Updates to install any available macOS and app updates. Software updates often include bug fixes and performance improvements that can help speed up an SSD.
Next, clear out caches and temporary files that may be slowing things down. Open the Disk Utility app and click “Clean up” on the SSD to remove unnecessary cached and temporary files [1].
Check for file system errors or corruption that could hamper performance. In Disk Utility, select the SSD drive and click “First Aid” to verify and repair the file system [2]. This can fix SSD issues caused by unexpected shutdowns or disconnects.
Finally, if you’re connecting your SSD externally, try replacing cables and using different USB ports. Faulty or slow cables can bottleneck SSD speeds. Use the fastest USB port available on your Mac, and make sure to use a high-speed USB 3 cable designed for SSDs.
Maximize SSD Lifespan
To extend the lifespan of your Mac’s SSD and avoid premature failure, there are several tips you can follow:
- Enable TRIM – Enabling the TRIM command allows the SSD to more efficiently handle garbage collection and rewrites, reducing wear. TRIM is enabled by default on modern versions of macOS, but you can verify it is active by checking System Information. Source
- Limit unnecessary writes – Avoid constantly writing and rewriting data unnecessarily, as this causes extra wear on SSD cells. Instead, plan batch file operations and limit auto-saving features in apps.
- Control heat – Excessive heat can reduce the lifespan of an SSD. Place your Mac in a well-ventilated area and use a cooling pad if needed.
- Enable Power Nap – Power Nap allows SSD maintenance like garbage collection to run while your Mac is sleeping. Keep this feature active to maintain your SSD.
- Manage temporary files – Temporary files like caches can fill up an SSD and require more writes when deleted. Regularly clear caches and temporary files using the built-in Storage Management tool.
- Avoid overfilling SSD – Keeping too much data on your SSD reduces available spare area and requires more write amplification. Maintain at least 10-20% free space.
Following best practices like these can significantly extend the usable lifespan of a Mac SSD before replacement is required.
Recover Deleted Files
If you’ve accidentally deleted files from your Mac SSD, there are utilities that may be able to recover them. One option is a free tool like Photorec, which scans the drive and attempts to reconstruct deleted files. However, Photorec does not recover filenames or folder structures – it simply grabs all recoverable data it can find. You would need to go through the recovered files manually to find what you need.
When using any data recovery tool, it’s critical to avoid writing new data to the SSD before recovering files. Any new writes can easily overwrite deleted data, making it unrecoverable. So once you realize files are missing, stop using the SSD right away.
For the best results, make a bit-for-bit clone image of the SSD before attempting recovery. This preserves your only copy of the deleted data intact. You can then run data recovery tools against the clone rather than risking the original drive. Tools like dd or Apple’s asr can be used to create clone images.
If you need to recover highly important or large amounts of lost data, consider seeking help from a professional recovery service. They use specialized tools in a controlled lab environment to give you the best chances.
When to Seek Professional Help
For complex drive issues or valuable data, professional assistance recommended. Data recovery firms like Ontrack, DriveSavers, and Kroll Ontrack employ data recovery experts with specialized tools to retrieve data from severely damaged drives. Though expensive, their services may be warranted for irreplaceable data like family photos/videos, important documents, or business records. They use techniques like chip-off, microscopic repair, and clean room recovery to salvage data from drives with mechanical, logical, or physical failures. For valuable personal or business records, the high recovery success rates and security controls of professional firms may merit the premium cost.
