Data Recovery Case File · Portable Drives · What He Did Immediately After
The Right Instinct at the Right Moment
His enquiry was mostly a technical description and ended with a sentence worth more than the rest of it. A 2TB second drive in a laptop: "the drive started making noises and Windows could not see it. Disk Management only sees the SSD and the same in the BIOS. Can you recover a drive like this, and what would I be looking at price-wise and turnaround with the Christmas holidays? I'm off out now, so please email. Going to go and get another external drive to back up the SSD." That last line is the reason this case is in the archive. He has just lost one drive and his immediate next action is to protect the one that still works — which is the correct response and one that almost nobody has while the shock is fresh.
| Media | 2TB secondary laptop hard drive — audible mechanical noise on power; absent from the operating system, its disk utility and system firmware; system SSD unaffected |
| Reported situation | Secondary drive failing abruptly with audible noise · not enumerated by the operating system, disk management or firmware · primary SSD functioning normally · owner immediately arranging a backup of the surviving drive |
| Fault class | Mechanical failure with no enumeration — head or motor fault requiring intervention; primary storage unaffected |
| Equipment used | No further power-up · laminar flow bench inspection of heads and surfaces before power · matched donor parts as indicated · PC-3000 Express with Data Extractor prioritised head-mapped imaging |
The decode: the technical picture, and why his next move matters
What the symptoms establish: a drive that makes noise and appears nowhere — not in the operating system, not in its disk utility, not in the firmware — has failed below every level software can reach. Firmware absence is the decisive observation: it means the drive is not completing the basic identification that precedes everything else, so this is not a filesystem problem, a driver problem or a partition problem. It is mechanical, and the noise says so.
Why the noise should be described precisely: a beep is the spindle motor straining against a stack that will not turn, usually heads adhered to a surface or a stiffened bearing. A click is the head assembly failing to position over platters that are turning. A squeal or grind suggests contact. Each points at different work, and reporting which he hears is worth more than any other description he can give.
Why stopping matters here specifically: a drive that appears nowhere gives a computer nothing to work with, so there is no diagnostic value in reconnecting it — and every attempt runs the mechanism through whatever is failing. On mechanical faults the number of power-ups is one of the largest determinants of what comes back.
Now the sentence that matters. Almost everybody in this position focuses entirely on the failed drive: they retry it, research it, and wait to hear what can be done. Meanwhile the machine's other drive — the one holding the operating system and, usually, most of their working files — carries on with no protection at all, in a laptop that has just demonstrated that storage fails without warning. He did the opposite, immediately, before the recovery question was even answered. That is the single most valuable habit this archive can encourage: the moment one drive fails is the moment to copy the others, because it is the only moment when the risk feels real enough to act on.
Why the timing is also fortunate: a second drive failing while the system drive is healthy is the good version of this. Had the SSD gone instead, he would have lost the machine and its working data together — and would have been reading this page about that instead.
On the seasonal question: a fair one. Turnaround should be confirmed in writing against his actual dates rather than estimated, and if anything on the drive is needed by a particular day, saying so allows imaging to be sequenced accordingly.
On the bench
The drive was not powered again, since a device absent from firmware offers a computer nothing further to establish and every attempt runs a failing mechanism. It was opened under the laminar flow bench and its head assembly, platter surfaces and spindle inspected before anything was switched on, with any scoring located and measured against the intact area. Matched donor parts were fitted where the findings required, and imaging ran on the PC-3000 Express under Data Extractor — head-mapped and prioritised, in one supervised session — with the timescale confirmed in writing against his dates.
The outcome
The mechanism inspected before power, serviced and imaged in one supervised session, with turnaround confirmed in writing. Free assessment, one fixed written figure including VAT, 50% of parts and labour upfront with the balance only on successful recovery. The decode, and the thing he got right: when one drive fails, copy the others immediately — the moment of failure is the only moment when the risk feels real enough to act on, and almost everyone spends it focused on the drive that has already gone; a drive absent from firmware as well as the operating system has failed below anything software can reach, so it is mechanical and reconnecting achieves nothing; and describe the noise precisely, because a beep, a click and a grind mean different things.
One drive has failed and you still have others
Back up the surviving drives today, before you do anything about the failed one. This is the single most useful habit going, and hardly anyone manages it — when a drive fails, all the attention goes to the one that's gone while the others carry on unprotected in a machine that has just proved storage fails without warning. Buy the external drive now, copy your system drive and anything else that matters, and then deal with the recovery. As for the failed drive: if it makes noise and appears nowhere, including in your machine's firmware, it has failed below anything software can reach, so stop reconnecting it — there's nothing more to learn and each attempt runs a failing mechanism. Note precisely what you hear, because a beep, a click and a grinding noise point at different faults.
