Data Recovery Case File · DIY Interventions · The Home Head Swap

The deepest anyone's gone before writing in: an amateur head transplant, audited under filtered air — and what survived it

This archive's DIY chapter has documented board swaps, chip transfers, and heads nudged back into their parks. This enquiry brought its boldest entry yet, reported with complete candour: after an electrical surge killed his 2TB IronWolf, "I had a friend who's done this type of thing before open up the drive and swap out the heads — but to no avail. I decided it's time to get the pros involved." His expectations were already calibrated — "I'm sure some hardware (board and/or heads) will need replaced from a donor" — and his practicality extended to the parcel: an empty 2TB external included for the recovered data, hoping to offset the cost. Pictures mostly, some music, documents. The audit his candour earned, and the recovery it permitted, follow — along with the honest accounting of what a home head swap risks, written for everyone whose capable friend is reaching for a screwdriver right now.

The audit — what a home head swap is up against, and what this one left behind

The honest ledger of amateur head work, itemised because his friend genuinely knew more than most: a head swap performed outside filtered air exposes surfaces engineered for particle-free flight to a room's worth of dust; it proceeds without the alignment tooling and protective combs that carry heads across platters untouched; and — the subtlest trap — it depends on generation-level donor matching that model labels don't reveal, so "compatible" heads from a similar drive routinely aren't. Any one of those can end a case; his audit, under laminar airflow, found the middle outcome this page reports without varnish. The fitted heads were indeed mismatched — the swap had never had a chance of taking — and the platters carried the light fingerprints of amateur handling at their edge territory: real, bounded, survivable. Two further findings shaped the plan. The original fault had never been treated at all: the surge had shorted the drive's board — the friend had transplanted heads onto a patient whose electronics were still dead, a wrong-organ diagnosis this archive's electrical cases explain — so board-level repair with the ROM preserved came first. And his supplied destination drive got its plain answer: yes, welcomed — return media is an itemised line in any honest quote, and supplying your own removes it.

The recovery

The rebuild ran in the order the audit dictated: the surge-shorted board repaired at component level, identity chip intact; the mismatched heads retired and a precision-matched donor stack fitted under the filtered air the first swap never had; and the drive — electronics alive and mechanism correctly voiced for the first time since the surge — imaged head by head on the PC-3000 at post-intervention tempo. Coverage closed in the mid-to-high ninety-nines, the honest shortfall mapping, as the audit predicted, to the edge territory the home handling had marked — itemised in the report, and landing (by geography's mercy) lightly among the pictures that were the drive's heart. The photo collection, the music, the documents: verified by opening them across the set, and delivered on the very drive he'd posted along for the purpose.

Outcome

Substantial recovery from a drive that had survived a surge and a home surgery — an outcome reported as the near-miss it is, not the endorsement it isn't. The accounting for his friend's tribe, capable people with steady hands and a dead drive in front of them: the head swap is this trade's signature operation precisely because everything around it — the filtered air, the combs, the generation-matched donors, the diagnosis of what actually failed — is the operation; the transplant itself is the visible tenth. This case ended well because the handling was careful, the disclosure complete, and the platters forgiving — three variables, only one of them chosen. The chosen one is the page's takeaway: whatever's been done, say all of it, as he did, and send everything — old parts, the friend's account, the lot. Candour converted his fourth-hand patient into a plan. The screwdriver's best contribution was stopping.
