I Was Told I Need a Clean Room

The My Passport is "connected to the laptop" but "does not show up", and makes "strange whirring/clicking sounds". She had been advised she would need a "clean room" for it, and mentioned in passing that a grandchild may have "stood on it". Both pieces of information point the same way, and the advice she was given was sound. A crush is an impact like any other — a portable drive under somebody's weight takes a shock through a head assembly flying nanometres above the platter, and the heads come off worse than the case does. The whirring is the platters turning; the clicking is the heads unable to read them. That combination is opened under a laminar-flow hood or not at all.

The decode

It is worth confirming the earlier advice rather than talking round it, because people are often told they need a clean room and then quietly suspect they are being softened up for a bill. They are not. A drive that whirs and clicks has a head fault, and a head fault is dealt with by opening the drive and replacing the head assembly. That has to happen in filtered air under laminar flow, because a single particle of household dust is many times larger than the gap the heads fly in, and a particle on the platter becomes an abrasive the moment things start turning.

The crush explains it neatly. People think of drops, but standing on a portable drive delivers a comparable shock in a different direction, and the drive does not much care which. Portable units have very little internal protection — they are a bare 2.5-inch mechanism in a plastic shell — so a foot on a drive lying on a carpet is entirely sufficient to knock a head assembly out of true.

The photographs themselves are in the least dramatic position of anyone involved. They are recorded on the platters, the platters are still turning, and the fault is above them. The one thing that would genuinely endanger them is continuing to plug the drive in to see whether it appears this time. She said there was no great urgency, which is the ideal answer: the drive goes in a padded box exactly as it is, and the free diagnostic tells her what she is dealing with inside 2 working days of it arriving.

On the bench

It was not plugged in again. Taken out of its enclosure and set on a current-limited bench supply, the whirring and the clicking were characterised without letting the drive run on. It was opened in filtered air under laminar flow, and the head assembly and platter surfaces were examined under a stereo microscope with particular attention to the area where a crush would have loaded the heads onto the surface. Matched donor heads were fitted, the alignment set, and imaging ran on DeepSpar behind PC-3000 UDMA in controlled passes, with the photographs located in R-Studio and rendered.

// the outcome

The outcome

Head assembly replaced in filtered clean air, the drive imaged, and the family photographs put onto fresh media. The diagnostic cost nothing; the figure that followed was fixed, written and inclusive of VAT. Because the drive had to be opened, 50% of that figure was payable in advance against the donor parts and the bench time, with the balance falling due only once the pictures were proven back. Whoever gave her the original advice deserves the credit for the outcome, since the drive arrived unplugged and unmolested.

A whirring, clicking drive somebody has told you needs clean air

Take the advice — it is not a sales line. Whirring plus clicking means the platters are turning and the heads are not reading, and the only route to your photographs is to open the drive and fit a matched head assembly under laminar flow, where the air is filtered finely enough that nothing settles on the surface. What you should not do in the meantime is keep connecting it to see whether it appears, because each attempt drags failing heads across the recording surface. And if something heavy went over it, say so when you ring, even if the case looks perfectly fine: a portable drive is a bare mechanism in a plastic shell, and being stood on does the same job as a drop from a table.

Something similar sitting on your desk? Every job on this site begins the same unhurried way: a diagnostic that costs nothing, done within 2 working days of the parcel landing on the bench, and then a single written figure that does not move afterwards. Logical faults carry no fix, no fee. Where a drive has to be opened, or its board rebuilt after impact, an electrical fault, water or fire, 50% of the quote falls due first and the rest only on success. Ransomware, CCTV recorders, BitLocker volumes and other forensic-classed jobs are settled in advance and in full. Where the data sits inside a laptop, a desktop, a Mac or a server, take the drive or SSD out and send that by itself: we do not remove internal drives from machines, and memory soldered onto a logic board (Apple Silicon Macs and the like) sits outside what we take. If it unplugs or unscrews, it is our sort of work. Post it tracked and insured to Cambridge Data Recovery, Compass House, Vision Park, Chivers Way, Cambridge CB24 9AD, use a courier you book and pay for yourself, or hand it over the desk there — there is no collection service.
