Odd Noises, Then It Stopped

The decode

Odd noises before stopping are a mechanical fault. That the drive made odd noises and then stopped points at a mechanical fault, because the parts that move — the motor that spins the platters and the heads that read them — make unusual sounds as they begin to fail, and when they can no longer run, the drive stops. The noises were the mechanism giving warning, the stopping where it failed, rather than the data being gone. His data is usually still on the platters, reached by working the drive in clean air. Odd noises before stopping are a mechanical fault, not lost data.

The platters usually survive it. That the mechanism failed does not mean the platters did, because the platters that hold the data are separate from the motor and heads, and a mechanical fault that stops those parts usually leaves the recording surfaces intact — unless the drive was run on through the noises and failing heads touched them. So the data is generally safe where the drive was not forced after it began to sound wrong: the fault is in the mechanism, and the platters behind it hold their recording, read once the mechanism is repaired or the platters moved to a working base. His data is reached from those platters, the mechanism addressed around them. The platters usually survive it.

It's worked in clean air, the data written out. Because the fault is mechanical, the drive is opened in clean air — the failed part addressed and alignment set, then imaged, so the data is read once it turns cleanly and written to fresh media, which a drive he supplies serves to hold as well as one provided. And a mechanically failing drive run on can score its platters, so it is not run. The free diagnostic establishes the state of the platters, and one fixed quote goes in writing before you owe a penny.

The honest prognosis rests on the platters. If the mechanism is the fault over intact platters — the usual case for a drive set aside once it sounded wrong — clean-air work lets it image and the data come back, often in full. If the platters were scored by running on, recovery narrows to the intact regions, confirmed before anything is agreed.

On the bench

The drive was not run on given the noises. It was taken from its enclosure and profiled on a current-limited bench supply, the mechanical fault localised. It was opened in clean air under laminar flow, the motor, heads, and platters inspected under stereo microscope, the failed part addressed — matched donor heads fitted or the motor freed, or the platters transferred to a matched base, alignment set. It was imaged on DeepSpar behind PC-3000 UDMA, the data located in R-Studio and written to fresh media.

The outcome

The mechanical fault addressed in clean air, the drive imaged, and the data written to fresh media. The diagnostic stage is free and reports back within two working days of the media arriving; after it you hold one written quote, fixed with VAT included. Opening a drive commits donor stock and clean-air bench time, so half the quoted figure is payable before that stage begins, and the remaining half falls due only once the recovery has succeeded — if it fails, the rest is never billed. The decode: odd noises before a drive stops point to a mechanical fault — worked in clean air, the platters usually spared. Worked with sound platters, your data comes back.
