A Repair Place Said It's Mechanical

A Seagate that wouldn't work, taken to a repair facility, diagnosed as having a mechanical failure, and they suggested sending it to a lab instead of attempting to fix it themselves. Both of those were correct and worth noting, because the alternative way of telling the same story would end much worse. A mechanical failure means that something in the sealed case (the heads, the arm holding them, or the spindle motor) went bad, but the data remains intact on the platters under the heads. To access the data you need to open the drive using matched donor parts (this is generally beyond what most repair shops can accomplish, and also should not be attempted by them). If a repair shop can run the diagnostic tests, read the results accurately and stop, then they've completed their helpful portion of the job.

// case at a glance
MediaSeagate hard drive, mechanically failed. Diagnostics run by a repair shop, which advised laboratory recovery rather than attempting the work.
Reported situationSeagate drive · broken · a repair place ran diagnostics · found mechanical failure · advised taking it to a lab · recovery sought.
Fault classMechanical failure inside the sealed casing. The heads or the spindle motor have failed, so the drive cannot read. The platter data is normally intact and is reached by working the drive under laminar flow with matched donor parts. The shop's diagnosis and its refusal to open the drive were both correct.
Equipment usedDiagnosis confirmed independently on a bench supply with the current limited behind PC-3000 UDMA, the fault localised to heads or motor · opened under laminar flow in filtered air, with the head stack and the platter surfaces examined at magnification, the failed heads or motor replaced with matched donors, or the platters moved across to a matched donor base, alignment set afterwards · imaged on DeepSpar, data located and validated in R-Studio.

The decode

Failure in mechanics isn't just one issue; it's a whole family. Narrowing this down affects how the job is done, as well as what the costs will be. Heads fail the most often (and usually make their presence known by clicking or a repeating rhythm). When an arm fails, the drive spins normally but reads nothing. A seized spindle produces complete silence, heat and excessive current draw. The donor part needed for each is different along with the order of the steps involved.

They have something in common, in that all of their platters are below them, unaltered. No mechanical failure will erase any data. Data recorded remains where it was written; what is required is getting the drive able to read it again for long enough to create a full copy of it.

A laboratory is chosen over a workshop not out of snobbery about tools but primarily due to particulate contamination. A magnetic head travels across a platter at a height of nanometres. Ordinary indoor dust would appear as large specks in these dimensions. If a particle got under a head during operation, it would act like a machete cutting into the platter surface.

So the shop stopping was the customer's good fortune. The common alternative is somebody opening the casing on a workbench to have a look, which contaminates the platters permanently and converts a routine head swap into a partial salvage. A drive that arrives unopened, switched off and undisturbed is the best possible starting condition, and that is exactly how this one arrived.

On the bench

The shop's findings were confirmed as opposed to being relied upon. The drive was connected to a bench power supply with the current restricted behind PC-3000 UDMA; prior to opening anything, the failure was traced to either the heads or the motor based upon behaviour and current draw. Once it was opened, it was examined using a microscope at high magnification. A matching donor replacement for the failed part was installed (heads and their arm assembly, or the motor, or where the spindle itself had gone, the platters moved across onto a matched donor base) and the alignment was set. Data was captured from the drive with DeepSpar and compiled into an image. The image was then imported into R-Studio, where the data was assembled and verified.

// the outcome

The outcome

The mechanical fault repaired on the bench, then the drive was imaged, and the recovered information was placed back onto new media. There were no charges for assessment; there was only one charge, a single fixed written price including VAT, given prior to opening the case. Since the physical work used donor components, as well as consumed many bench hours, half the cost was paid before that stage, and the remainder was due only on the result. It should be noted plainly that the repair facility did contribute to the process: they ran the test(s), properly interpreted the results, refused to open it at their location, and sent the unit on with it switched off. This combination is what made this a routine repair and not a challenging repair.

A drive a repair place found mechanically failed

Take their word for it. If the unit fails mechanically, the sealed casing will need to be opened by a laboratory equipped with a matching set of donor parts, something that can never happen on a work bench. Do not allow anyone to open it first just to "take a gander", even if they assure you they will be extremely careful when opening it. Contamination on a platter is permanent, and is the number one reason why you may get all of your data back, or only part of it. Never turn it back on to test whether the repair shop made the correct diagnosis. If the diagnosis is mechanical, any attempts to do so are damaging. Get a quote before posting us anything. Then post the bare drive itself (switched off) and securely packaged so it cannot move (or bring it into our Edinburgh lab, Monday to Friday, 9am to 5:30pm, no appointment needed). Be sure to mention which repair shop performed the diagnostics, along with their findings. A repair shop's diagnostics save time and get checked rather than duplicated.

The item you're reading this about may be sitting on your desk today. The same process applies to everything we've outlined: a complimentary assessment (completed within 2 working days of the unit arriving at our bench), followed by one written price which never goes up afterwards. For all forms of logical fault, in most cases you only pay if we recover your data. If the housing requires disassembly or the internal components require repair due to a drop, flood, electrical surge or fire damage, one-half of the quoted amount is due up front and the remaining balance only if we recover your data. Any items deemed "forensic" such as ransomware, camera and DVR recorders, BitLocker volumes etc. are always paid for in full, in advance. If the files reside within a piece of equipment (laptop, computer, server, desktop, Mac), simply remove the hard drive or solid state drive and post it separately to us. From a server, every disk should be sent, each labelled with its respective bay. A single external drive including its power adapter and cable should be sent complete. We do not dismantle computers nor do we accept flash memory permanently soldered to a logic board (such as T2 and Apple Silicon Macs); we also do not accept mobile devices such as smartphones and tablets. If you're unsure what type of device you have, contact us before sending anything. Simply unscrew or unplug and we will accept it. First obtain a quote either over the telephone or via the free online diagnostic tool, then send the unit tracked and insured to Edinburgh Data Recovery, 4 Redheughs Rigg, Westpoint, South Gyle, Edinburgh EH12 9DQ. Alternatively, arrange and pay for a delivery company of your own. You may also bring it to our premises located at Edinburgh Data Recovery, 4 Redheughs Rigg, Westpoint, South Gyle, Edinburgh EH12 9DQ, Monday to Friday, 9am to 5:30pm, with no appointment needed. No device is ever retrieved from a client. Packing notes and the shipping form sit here.

Each file below comes from a genuine enquiry taken from households and firms across Aberdeen, Aberdeenshire and the wider north-east, anonymised so nobody can be identified. Each one sets out how the fault was reasoned through, what was done about it, and which equipment did the work.

Recognise your own drive in this one?

The assessment is complimentary and will take no longer than 2 working days after receipt of your drive. Once this is done, the figure of cost will be fixed in writing. In the event that the work being completed is logical, in most cases you only pay if we recover your data. Begin online or call us.
