Years of a Bad Socket, Then One Long Tone.
This Backup Plus had been awkward for years: its micro-USB socket held only if you lift the plug a little and lean it left
, and a folded cigarette packet propping up the cable had become a fixture on the workshop bench. Then the sound changed. Light on, one flat tone that never stopped, and nothing in the Henley-on-Thames workshop would see the drive. A shop in town offered to reflow the socket; he rang us first.

In everyday terms.
The socket had years of credit as the thing that goes wrong here, which is exactly what made it dangerous. A worn connector interrupts: copies that halt part-way, a disk that vanishes and comes back, files that arrive damaged. What it cannot do is stall a motor, since a poor contact interrupts rather than obstructs. One flat, unbroken tone is a spindle straining against something that will not turn, and in a portable disk that is nearly always heads which have settled onto the platters and stuck fast. The fault had moved out of the connector and into the mechanism, and reflowing the connector would have mended the half that no longer mattered.
What the bench used here.
How a job is handled →| Tool | Why we used it | What it brings |
|---|---|---|
| ACE Lab PC-3000 Express | Told the years-old connector fault apart from the stall that had just started | Reaches the vendor-specific commands that ordinary ATA has no way of issuing |
| PC-3000 Data Extractor | Copied the bare disk over SATA, with the enclosure left out of it | The PC-3000's imaging module, working under firmware-level control |
| UFS Explorer Professional Recovery | Opened the finished image and took the restoration archive off it complete | Reads the awkward filesystems others stumble over: APFS, ReFS, XFS, ZFS, Btrfs |
The lab work.
Two faults, considered apart
A current-limited supply settled it inside two minutes: current climbing steadily, the motor labouring against something it could not shift, then the drive conceding and going quiet. A stall, unambiguously. His connector complaints were real enough and had no bearing on any of it, and since the enclosure was coming apart regardless, the socket left the job at that point.
Lift the heads off, leave the case behind
Opened under clean air, the heads were found resting on the platters, nowhere near the ramp they should have parked on. They came off, went under magnification, and the surface they had been lying against showed no marking at all. The disk then went onto an ordinary SATA port, which is the moment all those years of propping up a cable stopped being part of the story. The socket was never touched.
One pass, on a connection that holds
Turning freely again, it copied from first sector to last in a single overnight pass: no device dropping off and returning, no bus resets, none of the stop-start its owner had lived with. Very probably the cleanest run the drive ever made, and certainly its last.
How the job closed.
A decade of the workshop came back verified: each restoration photographed at every stage, the scanned manuals, the invoices for parts. It sits on two disks now, one at home and one left with his brother. The folded cigarette packet has been allowed to become rubbish again.

Does any of that match your case?
Nothing needs deciding until the diagnosis is back: switch the device off, send it in, and let the findings settle it.
