I pulled an old HFS-formatted Mac hard drive from storage, but it won’t mount properly and I need to recover photos and documents from it. I’m looking for reliable HFS recovery software for macOS or Windows that can scan an older Mac drive without making the data loss worse.
If the data matters, don’t treat the drive like something you’re trying to “fix.” Treat it like something you’re trying to copy data off of before anything gets worse. That means no formatting, no repeated First Aid runs, no saving new files to it, and don’t install recovery software onto that same drive.
With HFS and HFS+ drives, deleted files often still exist for a while. The file system usually just marks that space as free, so the real danger is new data being written over it. That can apply after deleting files, emptying the Trash, and sometimes even after a quick format. External drives can be a little more forgiving than internal ones because macOS usually isn’t constantly writing system files to them.
Before running a scan, I’d do a quick sanity check:
- See whether the drive shows up in Disk Utility with the right capacity.
- If it keeps dropping out, try a different cable, USB port, or Mac.
- Check SMART status if the enclosure actually passes that info through.
- If the drive freezes, disconnects, throws read errors, or SMART looks bad, make a disk image first and scan the image instead of hammering the original drive.
For HFS recovery, Disk Drill is usually the first tool I’d point people to. It handles HFS and HFS+, works with Mac internal and external drives, and can scan a device even when Finder won’t mount the volume, as long as the disk still appears with the correct size. The previews and recovery-chance indicators are useful too, since you can check whether the files are actually readable before committing to the recovery.
The basic workflow is:
- Install Disk Drill on your Mac, not on the HFS drive you’re recovering from.
- Connect the old external drive.
- Open Disk Drill and select the physical disk if you can, not just the visible volume.
- Run Search for Lost Data with Universal Scan.
- Wait for the scan to finish, then go to Review Found Items.
- Look through Deleted or Lost and Reconstructed.
- Preview the important files, especially photos, documents, and videos.
- Select what you want and click Recover.
- Save the recovered files to another healthy drive.
Do not recover files back onto the same HFS disk. That can overwrite other recoverable data that hasn’t been copied out yet.
If the drive is old and acting flaky, I’d use Disk Drill’s disk image feature before doing the normal scan:
Create the image on a separate drive with enough free space, then attach that image in Disk Drill and scan the copy. It won’t repair the original hard drive, but it reduces how much stress you put on failing hardware.
Also check the simple stuff first. Look in the Trash, since external drives can have hidden Trash folders too. If Time Machine has a backup from before the files went missing, use that before recovery software. TestDisk can be useful if the whole HFS partition was lost or deleted, but it’s text-based and easier to mess up. I’d think of it more as a partition-recovery tool than the best option for restoring one deleted folder.
A quick format does not always mean the data is gone. It often replaces file-system metadata while leaving a lot of the old file content sitting on the disk. The big factor is what happened afterward. If the drive was used a lot after formatting, recovery chances drop. You may also lose original file names and folder paths, especially when the software has to rebuild files by signatures instead of using intact HFS records.
One warning if you plug the drive into Windows: Windows does not natively read HFS+, so it may call the disk RAW and ask to format it. Don’t do that. Cancel the prompt. Some recovery tools on Windows may still scan it, but a Mac-based scan usually has a better shot at keeping the original structure.
I’d stop trying DIY recovery if the drive:
- clicks, grinds, buzzes, or keeps spinning up over and over
- vanishes from Disk Utility
- disconnects every few seconds
- freezes the Mac
- scans painfully slowly because of constant read errors
- has irreplaceable data and this is the only readable copy left
Those are signs of possible physical failure, not just deleted files or HFS corruption. Software can’t fix bad heads, damaged electronics, firmware problems, or badly degraded platters. At that point, repeated scans can make things worse, and a recovery lab is the safer route.
For a normal accidental deletion on a healthy old HFS external drive, the short version is: stop using the drive, check Trash and Time Machine, scan with Disk Drill, preview the files, and recover everything to a different disk. If the drive is unstable, image it first. If it clicks, disappears, or acts seriously damaged, stop powering it on and consider a lab.

Clone first, browse later. If this is a truly old HFS or HFS+ disk, the annoying bit is that some newer Macs and recovery apps may see the device but still do a poor job with the original folder tree, especially if the catalog file is damaged. Disk Drill is a reasonable first try if the drive is stable, but I would judge it by previews, not by the number of “found files” it reports. Lots of recovered JPGs with random names may be better than nothing, but it is not the same as a clean recovery. If you have access to an older Mac that can read the drive more normally, try that before doing a big recovery run on Windows. And do not let Windows “initialize” or “repair” anything it does not understand.
Expect the first scan to give you a pile of partial results, not a neat copy of the old desktop exactly as you remember it. HFS recovery is often limited by how much of the catalog is still readable, so I’d care less about which app finds the biggest number and more about whether it preserves names, folders, and previews the files you actually want. Disk Drill is fine for that first pass, but if it only gives you “reconstructed” files, try a second tool before paying or doing a huge recovery, because another scanner may read the directory records differently. And if this is a really old drive in a USB adapter, don’t overlook the adapter itself. A bad bridge board can make a healthy disk look like corrupted junk.
Check whether it’s actually HFS “Mac OS Standard” or HFS+ before you spend money on anything. A lot of people say HFS when they mean HFS+, but some very old drives really are plain HFS, and support for that can be patchier. If the software only advertises HFS+ or “Mac drives” in a vague way, don’t assume it will handle an OS 8/OS 9 era volume cleanly.
Disk Drill is a reasonable first swing, but I’d treat the free scan as the test, not the brand name. If it shows the old folder names and lets you preview the specific photos/docs, great. If it mostly gives you file000123.jpg type results, that may still save the photos, but your document organization is probably gone or only partly recoverable. Before paying, I’d compare with something like R-Studio or UFS Explorer if the directory tree matters.
Small annoyance people forget: old Mac disks can have Apple Partition Map, weird filename encoding, and old resource-fork stuff. For normal JPEGs, PDFs, Word docs, etc., that usually isn’t a big deal. For ancient Mac application files or classic Mac documents, recovery may look “successful” but the files may not open correctly unless the tool preserves Mac metadata. So previewing a few recovered files is more useful than trusting a big recovered-file count. And yes, if Windows pops up asking to initialize or format it, close that window like it’s trying to rob you.
