The LED Was On, the Disc Was Not.
Three winters of scanning gone due to one bump. A man in Anlaby Park had been going through his cine reels a spool at a time and cleaning out the slide boxes tray by tray, and everything was being copied to the same hard disk, until it tipped onto its side, mid-copy
. Since that time: the light still comes on
, there is no noise from it at all
, under a finger there is no vibration, and it does not appear on either computer

What causes it.
That LED is connected to the power rails. That's all it tells you. It doesn't know anything about the disk. Remove the spin-up noise and there are now three possibilities remaining inside the chassis. The heads may have fallen onto the recorded surface and stuck. The spindle bearings could be locked. Or the board simply never issued the motor a start signal. Run it on a bench supply and observe what current it pulls. Each of the three draws a different shape, so a few minutes is enough to tell them apart. He had a spare cable to try next. That would not have mattered.
The tools this one needed.
The steps we follow →| The gear | What this one did | Why we have it |
|---|---|---|
| ACE Lab PC-3000 Express | Current draw and its replies together put the fault in the mechanics | Reaches the vendor service commands an ordinary ATA connection cannot |
| PC-3000 Data Extractor | With the heads free, took the full surface in one unbroken pass | Copying is run at firmware level, with the PC-3000 in charge |
| R-Studio Technician | Rebuilt the folder structure, then tested each file by opening it, not counting it | Handles almost any file system, and puts RAID sets back together |
The stages.
Put a meter on it first
Off the USB lead and on a supply that measured current, it showed something none of your laptops will show you. A steep increase when the motor tried to spin; then a complete stop against whatever had pinned it; then the same pattern repeated on the second run. Failed boards always draw low and steady from start to finish. This didn't do that or anything like that. One reading was sufficient to locate where the failure occurred.
Get the heads off the surface
Once it was open, the mechanical parts confirmed the readings from the meter. Because the tip occurred while writing to a disc, no "park" instruction reached the actuator. The heads had fallen onto the recorded surface and were holding onto the spindle wherever it froze. The read/write heads came off individually, and the strip of platter under each of them was placed under a stereo microscope, as heads left in place will continue grinding their way into the data.
Start it once and copy everything
Freed, the motor spun up at once and the drive reported itself properly. The whole surface then copied in a single run. Nothing was opened en route and nothing was browsed. A mechanism that has jammed once can jam again with no notice at all.
How it finished.
All of the platters were free from marks. This is typical behaviour for a drive that has not been repeatedly tried. Everything was returned: all of the reels he had run through the scanner, as well as slides, verified to new media. The S3 was discarded. Now the films are stored in three different locations and his sister owns one set.
