How Podcasters Can Recover a Failed Drive (Our Real-World Rescue Story)

Podcasters live and die by their recordings. Losing raw interviews, DAW session files, or a full season of edited episodes can set you back weeks — or permanently erase irreplaceable content.

We learned this the hard way. An older transfer drive of ours failed with live data on it, and the backup copy turned out to be corrupted. The drive would still mount, but transfers slowed to a crawl and eventually it would drop off mid-copy. Normal methods just didn’t work.

Thankfully, with the help of GNU ddrescue and some patience, we got everything back. This post shares that recovery process, the requirements for attempting it, and what podcasters should do to avoid being in this situation at all.

1. Recognizing the Signs of Drive Trouble

Our drive didn’t make the dreaded “click of death.” It mounted normally, and the file tree looked fine. But:

  • Transfers slowed to near-zero.

  • The drive would disconnect mid-copy.

  • A “backup” we tried to fall back on turned out to be unreadable.

👉 Takeaway: Even a drive that looks fine can be failing. If you see extreme slowdowns, failed copies, or unmounting — stop using it immediately.

2. What We Did First (and What You Shouldn’t Do)

  • We didn’t run Disk Utility First Aid (Mac) or chkdsk (Windows). These can write changes that make recovery harder.

  • We didn’t reformat or initialize the drive.

  • Instead, we disconnected it and researched recovery methods that don’t write anything back to the failing drive.

3. The Recovery Process That Worked

Here’s how we saved our podcast files:

  1. Cloned the failing partition with ddrescue → created a sector-by-sector .img file. It took days to accomplish this. Be prepared!

  2. Used a map file → ddrescue kept track of good vs. bad areas, so we could pause/resume without losing progress.

  3. Wrote the image back to a healthy drive → this gave us a clean copy of the original.

  4. Mounted the image → from there, we copied files normally at full speed.

Result: 100% of our data recovered. Thankfully, we took note of the file sizes before the transfer, so we knew exactly how much data was on the drive. Once we finished with ddrescue, we were able to verify the file sizes.

4. Our Rescue Script

This is the script we used.

What it does:

  • Reads from the failing partition (/dev/disk2s2 in this example).

  • Clones it into an image (drive.img).

  • Uses a map file (drive.map) to track progress and retries.

⚠️ You must change DISK_NUM, SLICE, and file paths for your system.

#!/usr/bin/env bash
set -euo pipefail
# — Paths to your image and map file —
IMG=“/path/to/recovery/drive.img”
MAP=“/path/to/recovery/drive.map”# — Device info (change for your system) —
DISK_NUM=2 # external shows up as disk2
SLICE=2 # partition number (e.g., s2)
DEV=“/dev/disk${DISK_NUM}s${SLICE}# — Partition size (bytes, example: 1.5TB) —
TOTAL=1500000000000

# — Core ddrescue command —
sudo ddrescue -r1 $DEV $IMG$MAP

5. Requirements (Besides a Healthy New Drive)

If a podcaster wanted to try this approach, here’s what they’d need:

  • Computer: macOS or Linux with Terminal access.

  • GNU ddrescue installed:

    • macOS → brew install ddrescue

    • Ubuntu/Debian → sudo apt install gddrescue

  • Enough free space → as large as the entire partition (e.g., 1.5TB partition = 1.5TB free space). If you need a reliable storage solution, consider our recommended multi-use, multi-drive NAS.

  • Correct partition identification → run diskutil list (macOS) or lsblk (Linux).

  • Sudo privileges → raw disk access requires admin rights.

  • Time & patience → recovery can take hours or days.

Optional but helpful: a good USB/SATA dock, smartctl for health checks, and a UPS to avoid power cuts mid-run.


6. When This Works (and When It Doesn’t)

This method is best if:

  • The drive still spins and mounts.

  • File copies fail, but the partition is visible.

  • You need everything cloned, not just a few cherry-picked files.

It won’t help if:

  • The drive is clicking, grinding, or not recognized at all.

  • The electronics are dead.

  • The data is on an encrypted partition without the password.

Those cases require professional clean-room recovery.


7. The Lessons We Learned

  • A drive can “look fine” but still be in serious trouble.

  • Standard copy methods often choke on bad sectors.

  • ddrescue’s mapfile-based approach was the key to full recovery.

  • A bad backup is as bad as no backup — test them regularly.

  • The only real protection is redundancy (3-2-1 backup rule), which is why we recommend a multi-drive setup for redundancy.


Conclusion: Recovery vs. Prevention

Recovering our failed transfer drive with ddrescue was a relief, but it also showed how fragile podcast production workflows can be. If you’re a podcaster, think of recovery as your last resort — and backups as your insurance policy.

Because when you’re in the middle of a season, the last thing you want is to be Googling “how to rescue a failed drive” at 2 a.m.
