External media recovery: get back what can be saved, without putting the media at risk

· 4 min read

An SD card formatted by mistake in the camera, a USB stick that suddenly shows an empty folder, an external drive where part of your files has vanished: these situations are common and often fixable, as long as you act methodically. MacNeat's recovery feature is built for these external media. It scans their contents, finds deleted files that are still recoverable and restores them always to a different location than the original media.

It does not perform miracles and does not pretend to: depending on the type of media and what happened after the loss, some data is simply gone. This page explains what the tool does, how it does it and where its abilities end.

Which media, which situations

Recovery works on the media you connect to your Mac:

  • External hard drives and SSDs (USB, Thunderbolt), formatted as APFS, Mac OS Extended, exFAT or FAT32.
  • USB flash drives, usually exFAT or FAT32.
  • SD and microSD cards, through a built-in reader or an adapter.
  • Cameras that mount as a storage volume, or their card inserted into a reader.

Typical cases: files deleted in the Finder and the Trash emptied, an accidental quick format, a card removed mid-write, a volume that became unreadable after a power cut. The feature does not apply to files erased from the Mac's internal drive: for those, protection has to happen beforehand, with MacNeat's data protection and your backups.

How a recovery runs

  1. Pick the media: MacNeat lists the connected external volumes and you select the one to examine.
  2. Read-only scan: the tool goes through the existing contents and looks for deleted files whose data is still readable. Nothing is written to the media during this step.
  3. Review the results: files found are grouped by type (photos, videos, documents, archives) with their size and, when possible, a preview so you can check they are usable.
  4. Restore elsewhere: you choose a destination on the Mac's drive or on another disk. MacNeat refuses to restore to the media being scanned.

The scan is free: you see what can be recovered before committing to anything. Restoring is one of the actions that require a license (7-day trial included).

Why files are never restored to the source media

A deleted file is usually not wiped right away: the space it occupied is simply marked as free. As long as nothing is written over it, its data remains readable. Writing to the media, including restoring other files to it, can overwrite exactly what you are trying to save.

Hence two rules that MacNeat enforces and reminds you of:

  • Stop using the media as soon as you notice the loss: no more photos on the card, no more copying to the stick, no reformatting.
  • Always restore to another location, with enough free space for the recovered files.

Our guide on recovering data from external media covers what to do, and what to avoid, in the first few minutes.

The limits, plainly stated

No serious tool can guarantee a result. Here is what reduces or prevents recovery:

  • SSDs and TRIM: on most SSDs, the TRIM command tells the controller which blocks are free, and it often erases them very quickly. A file deleted from an external SSD can become unrecoverable within moments.
  • Encrypted APFS: on an encrypted volume, deleted data can only be read if the volume is unlocked with its password, and even then freed blocks are rarely readable.
  • Phones: an iPhone or Android phone does not expose its raw storage to the Mac. MacNeat can only read accessible files (visible photos and videos), not deleted items.
  • Overwriting: the more the media was used after the loss, the lower the chances.
  • Hardware failure: a drive that clicks, overheats or is no longer detected needs a specialist lab, not software.

We do not publish any success rate: it depends entirely on your situation.

MacNeat's principles apply here too

  • Local processing: scanning and restoring happen on your Mac. No file is sent to our servers.
  • Nothing deleted: recovery removes nothing. If you tidy up afterwards, everything goes through the Trash and can be undone.
  • Apple Silicon and Intel: the feature runs on both architectures, on the macOS versions MacNeat supports.
  • Clear permissions: accessing an external volume may require the "Removable Volumes" permission; MacNeat explains it when needed.

Frequently asked questions

Can I recover files erased from my Mac's internal drive?
No, this feature is dedicated to external media. On the internal drive (an SSD with TRIM, often encrypted with FileVault), recovery after deletion is rarely possible. The reliable answer is the Trash, Time Machine and MacNeat's secure trash.
My SD card was formatted in the camera. Is there a chance?
Often yes after a quick format, provided nothing else is saved to the card. Take it out, put it in a reader and run the scan: you will see for free what can be recovered.
Why won't MacNeat restore to the same USB stick?
Because every write to the original media can overwrite files that are still recoverable. Choose a folder on the Mac or another disk with enough free space.
Does it work with my iPhone?
Only to read accessible files, such as visible photos and videos. A phone does not give access to its raw storage, so deleted items cannot be recovered this way.
Are my files sent anywhere?
No. Scanning and restoring take place entirely on your Mac.
