A New Rattle, Then Nothing on Screen.
The Expansion had been riding all season in her van's door pocket (it lives in the van, site to site
) and, having taken a bumpy ride over rural farm roads around the Teign valley for a week, it picked up a rattle when it spins
. She kept using it, and after a few more days it disappeared entirely: gone from Disk Management as well
, on both her laptop and her husband's, and a new lead changed nothing
either.

In plain English.
Nothing moves freely in a healthy hard drive other than those parts intended to move: platters on their bearing, heads on their pivot. Thus when there is rattling during the spin-up of a hard drive, there is something breaking that rule (i.e., a fragment is loose in the housing, or a fastener has come undone, or the head assembly has some degree of movement), and each subsequent rotation offers the loose object one additional opportunity to encounter a platter. All her own checks had already accomplished what she needed them to do in terms of sorting out the problem: two laptops, a new lead, complete quietness everywhere, and this narrowed the source of the problem down to within the enclosure before she ever began packing the parcel.
The tools this job took.
See how your case runs →| System | The part it played | Why we rate it |
|---|---|---|
| PC-3000 Data Extractor | Commanded the read after the rebuild, surface by surface, on a short leash | The PC-3000's imager, taking its orders from the firmware side |
| DeepSpar Disk Imager 4 | Its head map drew the line between five clean surfaces and one scored | Images by head map — timeouts, resets and power-cycling managed per head |
| UFS Explorer Professional Recovery | Raised the NTFS volume from the image with its folder tree standing | Handles the harder filesystems well — APFS, ReFS, XFS, ZFS and Btrfs |
On the bench.
Trace the rattle to its part
Once the drive was open, the cause of the noise was very evident: the crash stop of the actuator had broken off and its stub was loose in the case; the head stack had also picked up some additional travel that it was never intended for (one of the suspensions had bent slightly). The platters were placed straight under the stereo microscope, since if there is movement in a head stack when seeking, you could potentially get contact with a surface at any point during a seek.
Rebuild the mechanism first, then survey every surface
The first action taken after reassembly, with a matched donor assembly in place of the damaged stack and the broken stop, was a survey, instead of a copy. The head map revealed an accurate picture: five surfaces read clean; the sixth surface had a score line along its outer band, evidence of the days that unit had kept on being called upon to do its job.
One guarded pass, and then retirement for good
It all happened in one go, during that one long session. First we banked the clean surfaces; lastly, we read the scored band with great care and slow speed, while the imager waited patiently. Donor heads are only loaned, they are not fitted for life: the drive got used only once and was then retired forever.
How it ended.
We got all five clean surfaces back intact. The scored one lost some files from a single garden's folder (each lost file is identified by name in the report). Now her archives reside on two separate drives, neither of which is in the van.
