Repeated Attempts to Reach Speed Mean the Motor Is Trying and Not Succeeding
His enquiry reports a physical sensation rather than a sound, which is unusually precise. An external drive that stopped working after a routine shutdown, where "I can feel it trying to spin a few times but then stops" — and he is candid that if the cost is high he will not pursue it. Feeling the attempts through the casing establishes something a sound could not: the motor is receiving power and the platters are not reaching speed.

The decode: what the sensation establishes, and why the price question matters
Why touch is a better instrument than hearing here: spin-up is a vibration before it is a sound. A drive attempting to turn transmits it through the casing whether or not it produces anything audible, and an enclosure damps sound more than movement.
What feeling the attempt proves: power reaches the motor. The board is functioning to the extent of driving the spindle, which excludes a dead board and a failed supply stage.
What the repetition tells us: the drive is trying and checking. A drive that fails to reach speed retries, typically a fixed number of times, and then stops — the pattern he describes exactly.
Why stopping after several attempts is designed behaviour: continuing would damage the motor. A drive gives up rather than driving indefinitely against resistance, which protects the mechanism.
What prevents a drive reaching speed: two things principally. Heads resting on the surface and adhering to it, or a spindle bearing that has stiffened — both mechanical, and both requiring the drive to be opened.
Why the normal shutdown is worth noting: nothing unusual preceded it. A drive that failed to start after an ordinary power cycle failed at rest rather than through an event, which points at adhesion or bearing wear rather than damage.
Why the recording is not implicated: the failure occurs before anything is read. Platters that never reached speed were never touched by moving heads, so the surfaces are in the state they were left in.
Why further attempts are the wrong response: each one drives a motor against resistance. Repeated attempts on adhered heads can damage them or the surface beneath, turning a good case into a poor one.
Now his other point, which deserves a straight answer: he has said he will not spend heavily. A mechanical fault requiring the drive to be opened sits at the higher end, and he should be told that before rather than after an assessment.
Why saying so is better than encouraging him: he has set a threshold and is entitled to a realistic bracket against it. A free assessment establishes the fault precisely, and he can decide with real information — but the honest expectation should be set now.
On the bench
Vibration through the housing was accepted as evidence of powered spin-up attempts — spin-up being a vibration before it is a sound, transmitted through the casing even where an enclosure damps the audible component, which establishes that power reaches the motor and excludes a dead board or failed supply stage. Drives retry a fixed number of times and stop rather than driving indefinitely against resistance. Failure before rotation leaves surfaces untouched. Inspection ran under the laminar flow bench.
The outcome
Vibration accepted as evidence of powered attempts, further connection stopped, and draw measured across the spin-up cycle. Free assessment, one fixed written figure including VAT, 50% of parts and labour upfront with the balance only on successful recovery — with the realistic bracket given before any commitment, since you have set a limit. The decode: feeling it is a better observation than hearing it. Power is reaching the motor and the platters are not reaching speed, which means the surfaces have never been touched.
A drive you can feel trying to start
Stop connecting it, because each attempt drives the motor against whatever is resisting it, and repeated attempts on heads that have adhered can damage them or the surface beneath. What you're feeling is useful: it proves power reaches the motor, which rules out a dead board, and the repetition is the drive retrying a fixed number of times before giving up to protect itself. Two things stop a drive reaching speed — heads resting and adhering, or a stiffened spindle bearing. Both need the drive opened, so ask for the bracket up front.
