Emergency
Dropped desktop hard drive
If your desktop hard drive was dropped it, the most useful thing on this page is above this paragraph, and it is free. What follows is what the fault usually turns out to be, how recoverable this class of failure is, and what it would cost, including the cases we would tell you to take elsewhere.
What this usually turns out to be
A bare SATA drive from a desktop. No enclosure to fail means a fault here is usually the drive itself rather than the thing it was plugged into.
Head assembly displaced or damaged
The likeliest serious outcome when a drive is dropped while running. Powering on afterwards is what turns it into surface damage.
Platter damage from head contact at impact
Where the heads struck the surface during the fall, leaving scoring already present before any power-up.
Nothing at allbetter news
Drives are designed to survive substantial shock while parked and idle. A drop onto carpet while switched off very often does no damage whatsoever.
Cracked solder joint or connector damagebetter news
Common on USB sticks and phones, where the impact is taken by the connector rather than any storage. The memory itself is usually intact.
How recoverable this is
Governed almost entirely by one question: was it running when it fell? A parked, powered-off drive dropped a short distance frequently survives with nothing wrong at all. A drive dropped while spinning is the harder case, and it gets harder every time it is powered on afterwards. Flash devices and phones fare much better: with no moving parts, a drop usually damages the connector or the board rather than the storage.
What moves it, for your device specifically:
- Whether the device was powered on and spinning at the moment of impact
- How many times it has been powered on since
- Whether the impact displaced the heads or damaged the platter surface
- For flash devices, whether the damage is confined to the connector or reaches the memory
We will not give you a percentage for your device, and you should be wary of anyone who does. Nobody can know what is recoverable until the media has been imaged and read. What is above describes this class of failure; your drive gets its own answer after an assessment, in writing, at no cost.
What it costs
Assessed free, then referred at no charge
Cleanroom mechanical work
Clicking, seized or head-crashed drives need internal mechanical work in a controlled environment. We don't have one, so we assess it, tell you what we found in writing, and refer it on. That referral costs you nothing here.
Nothing is charged until you have seen a fixed quote for your actual device and agreed to it, and the assessment that produces it is free.
Not quite your situation?
Pick the device and what it is doing, and this gives you the same answer for that combination instead.
