Hard Drive Shucking Guide 2025
Last updated: December 2025
Shucking is the practice of removing internal hard drives from external enclosures. It's often the cheapest way to get high-capacity NAS-grade drives.
Why Shuck?
External drives are frequently cheaper than their internal equivalents, especially during sales. A 14TB WD Elements might cost $200 while the equivalent WD Red Pro internal costs $300+.
The drives inside are often the same — or even better. Many WD externals contain white-label versions of their enterprise Ultrastar or NAS Red drives.
Best Drives to Shuck (2025)
| External Drive | Usually Contains | Sweet Spot |
|---|---|---|
| WD Elements Desktop | WD White Label (Ultrastar/Red) | 12-18TB |
| WD easystore | WD White Label (Ultrastar/Red) | 14-18TB (Best Buy exclusive) |
| WD My Book | WD White Label | 8-14TB |
| Seagate Expansion | Seagate Barracuda Compute | 8-16TB |
Best value: WD Elements/easystore 14TB+ during Black Friday sales. Often drops to $10-12/TB.
Tools You Need
- Plastic spudger or old credit card — to pry open clips without scratching
- Guitar pick — works great for WD enclosures
- Patience — rushing leads to broken clips and scratches
You do NOT need screwdrivers for most WD externals. They use plastic clips, not screws.
The Process
- Remove rubber feet — some WD models have screws hidden underneath
- Find the seam — usually along the long edge of the enclosure
- Insert spudger/card — work slowly around the perimeter, releasing clips
- Slide out the drive — may have a rubber sleeve or caddy
- Remove USB adapter board — usually held by 4 screws or plastic clips
Total time: 5-10 minutes once you've done it before.
Watch Out: 3.3V Pin Issue
Some shucked WD drives use the SATA 3.3V pin (Pin 3) for power disable, causing them to not spin up in older systems.
Fixes:
- Cover Pin 3 with Kapton tape (easiest)
- Use a SATA power extension with Pin 3 removed
- Use a PSU made after 2017 (many handle this correctly)
- Your NAS/server may not have this issue at all
What's Inside?
WD white-label drives are typically:
- HGST/WD Ultrastar — Helium-filled, datacenter quality
- WD Red equivalents — CMR (not SMR), NAS-rated
- 5400-7200 RPM depending on capacity
- Full 3-year warranty (if you register the external before shucking)
When NOT to Shuck
- You need the warranty: Shucking voids the external warranty. The internal drive has no warranty.
- 8TB or smaller: Price difference usually isn't worth the effort
- Seagate SMR drives: Some Expansion drives contain SMR (Shingled) drives — avoid for NAS use
- Portable 2.5" drives: Usually soldered USB, can't be shucked
Identifying the Drive Inside
Before buying, check r/DataHoarder spreadsheets. The community tracks which externals contain which internals.
Key identifiers on WD white labels:
- WD140EDGZ — 14TB, likely Ultrastar DC HC530
- WD180EDGZ — 18TB, likely Ultrastar DC HC550
- WD80EMAZ — 8TB, WD Red equivalent
Bottom Line
Best time to buy: Black Friday, Prime Day, or random Best Buy sales on easystore.
Sweet spot: 14-18TB WD Elements or easystore at $10-12/TB.
Avoid: 8TB or smaller (not worth it), Seagate Expansion (SMR risk), anything without community reports.
