A Report That Was Right at the Time
His enquiry arrived with documentation, which almost none do. A 500GB external drive with the click of death, sent to a laboratory in 2009 and returned unrecovered because the quote was more than he could justify — and he has kept their written evaluation ever since. It identified failed read/write heads, noted minimal contact with the platter surface, and put the chance of a successful recovery at eighty-five per cent. Fifteen years later he would like to know what it would cost now. That report is a competent assessment and every word of it is about a drive that no longer exists in that condition.
| Media | 500GB external hard drive with head failure — professionally evaluated in 2009, recovery declined on cost, drive retained and stored since |
| Reported situation | Drive failed with audible clicking · assessed by a recovery laboratory in 2009 · head replacement identified as required · minimal platter contact reported · recovery declined on cost · drive stored unrecovered for approximately fifteen years · costing sought now |
| Fault class | Documented head failure compounded by prolonged dormancy — original diagnosis sound; donor availability and storage effects now the governing constraints |

The decode: what the report still tells us, and what it cannot
Why the old evaluation is genuinely valuable: it is a professional assessment of the mechanism, made when the fault was fresh, by people who had the drive open. It identifies the failure as the read/write heads and records that contact with the platter surface was minimal. That second point is the good news in the document — extensive contact scores the surfaces permanently, while minimal contact means the recording layer was largely intact at the time. Arriving with that is worth a great deal, and he should send a copy.
One phrase worth decoding: the report described the head contact as having damaged the file system. That wording confuses people, because "file system" sounds like a software problem. In this context it means the physical damage fell in an area holding filing structures rather than that anything was logically corrupted — the distinction between a surface defect and a software fault, described in a way that reads as the latter.
What the eighty-five per cent figure meant: an experienced estimate of the likelihood of a substantially complete recovery, given the drive as it was on the bench that week, with parts then readily available. It was not a guarantee and it was not a permanent property of the drive. It was a snapshot.
What fifteen years of storage changes, and this is the honest part. A drive that has been opened, closed and stored has three things working against it that the report could not account for. Lubricant migrates and thickens, so a spindle that turned freely then may not now. Heads resting against a surface can adhere simply from remaining in contact for years. And any contamination introduced during the original evaluation has had a decade and a half to settle. None of that is fatal, and all of it means the drive now needs assessing on its own terms rather than on the strength of a historical document.
What has actually become the binding constraint: not the fault — the parts. Replacing heads requires a donor drive of the same model, firmware family and manufacturing batch, and for a 500GB drive from the late 2000s those are no longer manufactured, no longer stocked, and available only from the second-hand supply that recovery firms maintain. So the question that decides this case is not whether the drive can be repaired but whether a matched donor can still be found. That is established first, before anything is quoted, because a figure for work that cannot be sourced helps nobody.
Why it is still worth asking: the fault is well understood, the original assessment was encouraging, and donor availability for that era is thin rather than absent. It is worth finding out.
On the bench
The prior evaluation was taken into account before assessment — a professional report describing head failure with minimal platter contact narrows the picture considerably and tells the bench what to look for first. Donor availability was established before any work was quoted, since matched heads for a drive of that era are the governing constraint rather than the fault itself. Inspection ran under the laminar flow bench with attention to storage effects and prior handling — lubricant condition, head adhesion and contamination settled since the original opening — and imaging followed on the PC-3000 Express under Data Extractor.
The outcome
The historical evaluation used to narrow the assessment, donor availability established before any figure was given, and the mechanism inspected on its present condition. Free assessment, one fixed written figure including VAT, 50% of parts and labour upfront with the balance only on successful recovery. The decode, for anyone holding an old evaluation: send it, because a professional report identifying the fault and the extent of platter contact is genuinely useful. But understand what it cannot cover — years of storage thicken lubricant, let resting heads adhere, and allow any contamination to settle. And for a drive of that age the binding constraint is donor availability rather than the fault, which is why that is checked before anything is quoted.
Old drive with an evaluation you never acted on
Send the report — it's worth having. A professional assessment identifying the fault, and particularly one recording how much contact the heads made with the platters, tells whoever looks at it next exactly what to expect and saves duplicated work. Minimal contact is genuinely good news, because heavy contact scores the surfaces permanently. But be aware of what the years have added that no report could cover: lubricant thickens in storage, heads resting on a surface can stick to it, and any contamination introduced when it was first opened has had a long time to settle. And for an older drive the real question isn't the fault at all — it's whether matched donor parts still exist, since heads must come from the same model, firmware family and batch. Ask about parts availability first.
