How to Recover Files from an HFS+ Drive

TL;DR:

To recover files from a corrupted, formatted, or deleted HFS+ drive, immediately stop all write operations to the disk, run a read-focused scan using a tool like Recoverit Mac Data Recovery, and strictly save the retrieved data to a completely separate storage device.

● Do not run Disk Utility First Aid on clicking, freezing, or disconnecting drives before data is secured, as repair attempts can alter metadata and push unstable hardware into total failure.
● Create a disk image or clone to scan from if the drive is physically unstable, but note that FileVault-encrypted HFS+ drives will still strictly require the correct password or recovery key for access.
● If recovered files lack their original names or folder structures due to damaged HFS+ directory records, locate your specific data by sorting the scan results by file type, size, modified date, and using the preview function.

Files can often be recovered from an HFS+ drive if the drive is no longer being used for writes and the file system damage is limited. HFS+ recovery usually works best after deletion, formatting, lost directory records, or minor corruption. Recovery becomes less likely after overwrite, severe physical failure, encryption issues, or repeated repair attempts on the same disk.

Step 1
Stop using the HFS+ drive immediately. Avoid saving new files, running repairs, formatting, or reinstalling macOS on the same disk because new writes can overwrite recoverable data.
Step 2
Check how the drive appears in Disk Utility. If the HFS+ drive is detected but not mounting, note the reported size, file system status, and any error messages before taking further action.
Step 3
Create a disk image or clone if the drive shows errors, slow reads, disconnects, or unusual noises. Working from a copy reduces the risk of more file system or hardware damage during Mac HFS+ data recovery.
Step 4
Run a read-focused scan with an HFS+ recovery tool on the drive, clone, or disk image. Review found files by path, name, file type, size, date, and preview where available before restoring anything.
Step 5
Recover files to a different storage device. Never save recovered files back to the same HFS+ drive, especially after deletion, formatting, or directory corruption.

Common Issues and Fixes

Drive does not mount: likely cause is file system corruption, catalog damage, or hardware instability; fix by scanning the drive or clone in a read-focused workflow before attempting repairs.
Files appear with missing names or folders: likely cause is damaged HFS+ directory records; fix by sorting results by file type, size, modified date, and preview.
Scan finds few or no files: likely cause is overwrite after deletion, formatting, SSD TRIM, or encryption; fix by stopping all writes and rescanning from a disk image if possible.
Drive disconnects during scan: likely cause is failing hardware, unstable enclosure, weak cable, or power issue; fix by using a stable connection and cloning the drive first if it remains readable.
Recovered files will not open: likely cause is partial recovery, corruption, or missing file fragments; fix by trying alternate scan results and checking earlier versions or backups.

Quick Tips

HFS+ recovery may still be possible after accidental formatting if the new file system has not heavily overwritten old data.
First Aid can sometimes worsen access to unstable drives by stressing weak hardware or changing metadata. Recovery first is often safer when the drive clicks, freezes, or disconnects.
FileVault-encrypted drives require the correct password or recovery key. Without decryption access, meaningful file recovery may fail.
External drives with physical damage, liquid exposure, burn marks, or repeated mounting failure may need professional diagnosis.
After recovery, replace or reformat the affected drive only after recovered files are verified on separate storage.

💡Protip:

For HFS+ recovery, avoid repairing the volume before securing the files. Clone or image the drive if possible, scan the copy, recover important data to another disk, and only then decide whether First Aid, reformatting, or drive replacement is appropriate.
