It Clicks and Won't Be Recognised

The decode

Clicking is the heads failing to read. That the drive has started clicking points at a head fault — the read/write heads float just above the spinning platters and read the data, and when they cannot, they reset and retry, and that repeated reset is the clicking. So the sound is the fault made audible: the heads are failing to read and resetting, which is the click, rather than the recording being gone. Her data is usually still on the platters, behind those failing heads, reached by replacing them in clean air. Clicking is the heads failing to read, not lost data.

No recognition follows from the heads not reading. That the drive is no longer recognised follows from the same fault, because a drive presents itself to the computer only once its heads read the information that lets it report, so heads that cannot read leave the drive unable to identify itself, and the computer sees nothing to recognise. So the two symptoms are one fault: the heads can't read, which is both the clicking and the lack of recognition, rather than two separate problems. Her data is reached once the heads are replaced and read again. No recognition follows from the heads not reading.

The heads are replaced in clean air, not run on. Because the fault is in the heads, the drive is opened in clean air — the heads and platters inspected under magnification, the heads replaced with matched donors, alignment set, and the drive imaged, so the data is read once the heads read again. And because a clicking drive run on lets the failing heads touch and score the platters, it must not be powered further, as each attempt risks the surface where the data lives. Her data is reached from the platters, by clean-air head replacement, which is how a clicking drive is recovered. The free diagnostic confirms the platters, and one fixed quote goes in writing before you owe a penny.

The honest prognosis rests on the platters. If the heads are the fault over intact platters — likely if the drive is caught early and not run repeatedly through the clicking — clean-air head replacement lets the drive image and the data come back, often in full. If it was run on and the platters were scored, recovery narrows to the intact regions. Which applies is determined by inspection under magnification, with the recoverable extent confirmed before you decide — the data usually recoverable where the platters were spared.

On the bench

The drive was not run on given the clicking. It was taken from its enclosure and profiled on a current-limited bench supply, the head behaviour assessed. It was opened in clean air under laminar flow, the heads and platters inspected under stereo microscope, matched donor heads fitted, alignment set. It was imaged on DeepSpar behind PC-3000 UDMA, the filesystem parsed in R-Studio and the data validated.

The outcome

The head fault addressed in clean air, the drive imaged, and the data recovered onto 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 and quoted against the fault actually found. 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: clicking with no recognition is a head fault — addressed in clean air, so the drive must not be run on. Addressed with sound platters, your data comes back.
