Nothing Wrong With the Disk.
In 2012, a surveyor in Goole decided to close his practice and store all of his scanned client records onto an Iomega hard drive that was approximately 12 months old. The drive continues to receive power. The light is on and I can hear it spinning
, he said. However, the drive cannot be located on any computer. A shop had a look and could do nothing with it.
So he left having settled on the worst possible answer to why he couldn't access his data, and he was quite sure of it: the disc inside it has shattered

What causes it.
That plastic case contains two items and each item will deteriorate at a separate rate. The SATA disk at the rear is standard issue like those found in most desktop towers. In front of that is a very low-cost circuit board designed to convert SATA to USB. That circuit board does not get any cooling. Therefore, if your unit turns on, makes humming noises, but does not show anywhere, you suspect the components in this order: first, the bridge; second, the firmware; third, the mechanical system. A broken platter should be at the bottom of the list. A diagnosis exists to prove or disprove your worst fears.
The tools this one needed.
The steps we follow →| The gear | What this one did | Why we have it |
|---|---|---|
| ACE Lab PC-3000 Express | Interrogated the bare disk at vendor level; nothing in the replies was wrong | Reaches the vendor service commands an ordinary ATA connection cannot |
| RapidSpar | Imaged it — nothing further is called for on a disk this healthy | The gentler of our imagers, for drives that are still answering properly |
| R-Studio Technician | Opened the volume and spot-checked scans right across the archive | Handles almost any file system, and puts RAID sets back together |
The stages.
Undo the screws, put the disk on a port
Four screws later and the Seagate Barracuda was removed and placed on a bench connected via a SATA port. Half a minute of further investigation disproved his theory: the disk spun up; reported its exact make/model number; reported its correct capacity; and responded to vendor commands directly. All he had heard was a standard working drive vibrating through thin plastic casing.
Read the logs before phoning him
Although a disk may seem to be working normally, it may well have already begun to fail. Therefore, nobody called him until the reallocated-sector count and the grown defect list had both been read. Both represented normal values for a device of that type and age that had not experienced heavy usage. Reads across all zones returned successfully during the first attempt; none required retrying.
Image at full rate, then say what broke
The image was extracted cleanly from start to finish using the maximum reading speed of the drive. No attempts were made to coax or retry any areas; no new defects arose during the extraction process. This left one single potential area of fault: the bridge board had aged out, but the disk it was originally intended to support continued functioning flawlessly.
How it finished.
Scans were opened from each year the practice ran, and none of them had anything missing. The recovery went back to him on new media. That old Seagate has been put in a better enclosure and now does light duty as the second copy. Shattered platters did not come up again.
